drop wd lock in wdstart1() before calling the ata_bio hook; when called
from ata thread context, that can still need to sleep for wdc attachments
in wdcwait()

fix use-after-free for ata xfer on bio submission found by KASAN
driver ata_bio hooks read parts of the xfer after ata_exec_xfer()
call in order to determine return value, change so that the hook
doesn't return any value - callers do not care already,
as all I/O requests are asynchronous

this problem was uncovered by recent change for wd(4) to not hold
wd mutex during ata_bio call, the interrupt for the xfer might
thus actually fire immediately

adjust also ata_exec_command driver hooks similarily - remove all
completion and waiting logic from drivers, upper layer ata code
using AT_WAIT/AT_POLL changed to call ata_wait_cmd() itself

Fix kernel freeze for wdc(4) variants with ATAC_CAP_NOIRQ:

(1) Change ata_xfer_ops:c_poll from void to int function. When it returns
    ATAPOLL_AGAIN, let ata_xfer_start() iterate itself again.
(2) Let wdc_ata_bio_poll() return ATAPOLL_AGAIN until ATA_ITSDONE is
    achieved.

A similar change has been made for mvsata(4) (see mvsata_bio_poll()),
and no functional changes for other devices.

This is how the drivers worked before jdolecek-ncq branch was merged.
Note that this changes are less likely to cause infinite recursion:

(1) wdc_ata_bio_intr() called from wdc_ata_bio_poll() asserts ATA_ITSDONE
    in its error handling paths via wdc_ata_bio_done().
(2) Return value from c_start (= wdc_ata_bio_start()) is checked in
    ata_xfer_start().

Therefore, errors encountered in ata_xfer_ops:c_poll and c_start routines
terminate the recursion for wdc(4). The situation is similar for mvsata(4).

Still, there is a possibility where ata_xfer_start() takes long time to
finish a normal operation. This can result in a delayed response for lower
priority interrupts. But, I've never observed such a situation, even when
heavy thrashing takes place for swap partition in wd(4).

stop timeout handler while scheduling another part of partial I/O,
to avoid race between the timeout and I/O submission; the I/O
submission can sleep with xfer while waiting for the controller to
be ready once it gets to thread context, and timeout might cause
the xfer to be freed, leading to crashes due to use-after-free

Merge jdolecek-ncqfixes branch

- ata_xfer's are dynamicall allocated as needed using a pool, no longer
  limited to number of possible openings supported by controller; dump
  and recovery paths use dedicated pre-allocated storage
- moved callouts and condvars from ata_xfer to queue or channel, so that
  ata_xfer does not need special initialization
- slot allocation now done when xfer is being activated, uncoupled
  from memory allocation; active slots are no longer tracked by controller
  code
- channel and drive reset is done always via the atabus thread, and
  now executes with channel locked the whole time
- NCQ recovery moved to shared function, and run via the thread also
- added some workarounds for buggy error recovery AHCI emulation in QEMU
  and Parallels

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

reintroduce ATACH_IRQ_WAIT flag for attachments using wdcintr(), only
process the interrupt when the flag is set - this fixes spurious interrupt
during post-reset drive setup in wdc_ata_bio_start(), and wdc_atapi_start()

while those functions set WDCTL_IDS, this seems to be ignored by certain
(maybe all) PCI-IDE controllers; usually the implicit KERNEL_LOCK() would
prevent the interrupt anyway, but not when the start routine is started
from the atabus thread, which doesn't take it

Merge support for SATA NCQ (Native Command Queueing) from jdolecek-ncq branch

ATA subsystem was changed to support several outstanding commands, and use
NCQ xfers if supported by both the controller and the disk, including NCQ
error recovery. Set NCQ high priority for BPRIO_TIMECRITICAL xfers
if supported. Added FUA support.

Done some work towards MP-safe, all ATA code tsleep()/wakeup() replaced
by condvars, and switched most code from spl* to mutexes (separate
wd(4) and ata channel lock).

Introduced new option WD_CHAOS_MONKEY to facilitate testing of error
handling, fixed several uncovered issues. Also fixed several problems
with kernel dump to wd(4) disk.

Tested with ahcisata(4), mvsata(4), siisata(4), piixide(4) on amd64,
with and without port multiplier, both disk and ATAPI devices; other
drivers and archs mechanically adjusted and compile-tested. NCQ is
supported for ahcisata(4) and siisata(4) for any controller, for
mvsata(4) only Gen IIe ones for now. Also enabled ATAPI support in
mvsata(4).

Thanks to Matt Thomas for initial ATA infrastructure patch, and
Jonathan A.Kollasch for siisata(4) NCQ changes and general testing.

adjust reset channel and dump paths
- channel reset now always kills active transfer, even on dump path, but
  now doesn't touch the queued waiting transfers; also kill_xfer hook is
  always called, so that HBA can free any private xfer resources and thus
  the dump request has chance to work
- kill_xfer routines now always call ata_deactivate_xfer(); added KASSERT()s
  to ata_free_xfer() to expect deactivated xfer
- when called during channel reset before dump, ata_kill_active() drops
  any queued waiting transfers without processing
- do not (re)queue any transfers in wddone() when dumping
- kill AT_RST_NOCMD flag

This should also hopefully fix the 'polled command has been queued' panic

We have three sets of DTYPE_ constants in the kernel:
	altq		Drop 		Type
	disklabel	Disk 		Type
	file		Descriptor	Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

Add sata Port MultiPlier (PMP) support to the ata bus layer,
as described in
http://mail-index.netbsd.org/tech-kern/2012/06/23/msg013442.html
PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
  probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
  really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
  ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()

propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).

Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
  with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
  University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
  when SATA cable move was needed

The loongon2f+cs5526+jmicron PATA->SATA bridge cause an interresting issue:
1) because the CS5536 is not associated with a x86 CPU, interrupts are not
  ack'ed as it expects so interrupts cannot configured as edge-triggered
  (as is expected for a PCIIDE in compat mode)
2) the PATA->SATA bridge ignores the WDC_IDS (interrupt disable bit) so
  the PATA IRQ line gets asserted when resetting or running some polled
  commands. It also wrongly asserts IRQ when the (nonexistent) slave
  device is selected
2) wouldn't be an issue with edge-triggered interrupt because we would
   get a spurious interrupt and continue operation, a new interrupt only shows
   up when the PATA IRQ line goes low and high again. But because of 1),
   we get an unclearable interrupt instead, and the system loops on the
   interrupt handler.

To workaround this, introduce a WDC_NO_IDS compile option which runs
all polled commands (including reset) at splbio() and without sleeps,
so that the controller's interrupt is effectively disabled and
won't be reenabled before the interrupt can be cleared.

The conditions triggering this problem are speficic enough to handle
this via a compile-time option; no need for a run-time (e.g. a
config(9), device property or callback to disable interrupts) solution.

Add PIOBM (busmastering transfer using ATA PIO mode) support.
The PIOBM is used by only one driver (will be added later,
stay tuned) and intruduce an attribute "ata_piobm" so that
it will be conditionally compiled in.
The "ata_dma" (busmastering transfer using ATA DMA mode) and
"ata_udma" (busmastering transfer using ATA Ultra DMA mode)
attributes are also added for consistency, but unused for now.

Pull up revision 1.82 (requested by thorpej in ticket #2072):
- When starting an ATA or ATAPI transfer, handle the case where
(*dma_init)()
returns EINVAL, indicating that DMA cannot be done for this
transfer.
Fall back to PIO in this case.
- Add a geodeide_dma_init() routine that checks to make sure that
transfers
start on a 16 byte boundary, returning EINVAL if not.  Works
around a chip
bug that causes a hard system hang.
Problem reported and patch tested by Erik Fair.

Pull up revision 1.82 (requested by thorpej in ticket #553):
- When starting an ATA or ATAPI transfer, handle the case where (*dma_init)()
  returns EINVAL, indicating that DMA cannot be done for this transfer.
  Fall back to PIO in this case.
- Add a geodeide_dma_init() routine that checks to make sure that transfers
  start on a 16 byte boundary, returning EINVAL if not.  Works around a chip
  bug that causes a hard system hang.
Problem reported and patch tested by Erik Fair.

There are some cards that map the ATA control and IDE DMA registers
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.

To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.

	bus_space_write_4(tag, handle, offset, value)

becomes

	bus_space_write_4(tag, handles[offset], 0, value)

Reviewed by Manuel Bouyer. Tested on wdc_isa, wdc_pcmcia, viaide, piixide (i386)
and on cmdide (sparc64).

Make the ATA mid-layer appears as atabus, as proposed in
http://mail-index.netbsd.org/tech-kern/2003/09/25/0006.html
This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.

Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.

- DMA code cleanup: pciide_dma_finish() doesn't stop/unload the current DMA op
  if an IRQ was not detected, unless the force flag was given. Use this to
  detect if the IRQ was for us (closer to shared IRQ for controllers which
  don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
  Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
  (wdc_*), so that it's possible to attach an atapibus to something else
  than a wdc/pciide (Hi Lennart :).
  Overload struct scsi_adapter with struct atapi_adapter, defined
  as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
  to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
  Move atapi_softc to atapiconf.h so that it can be used by the underlying
  controller code (e.g. atapi_wdc.c).
  Add an atapi-specific callback *atapi_probedev(), which probe a drive
  in a controller-specific way, allocate the sc_link and fills in the
  ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
  to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
  It should now be possible to use a common ata/atapi routine to set the
  drive's modes (will do later).

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

- Add some debug printf (WDCPROBE) in _wdcreset_wait(), I've needed these
  2 times in the past
- Set up timeout per xfer instead of per interrupt. This helps with
  PIO transfer (we would call timeout()/untimout() several times for a
  transfer).
- If we missed an interrupt for a PIO transfer, reset and restart it
  immedialy, don't try to recover and continue. If we missed an interrupt we
  may have lost a read/write cycle on the IDE bus. If this happens 1) we
  corrupt data and 2) we enter an interrupt loop at the end of the xfer, as
  the drive has some more data to read/write, but the host thinks the xfer is
  done.
This last change fix the (or at last some of the) 'lookup after lost interrupt'
some peoples have been experiencing.

There's no ATA draft where it is required for the drive to set DRDY | DSC when
the disk is ready to transfer data, and in ATA-5 the DSC has been obsoleted.
So only wait for DRQ to transfer data. This can be made conditional on the
ATA version if it's proven to break with some drives (worked with all the
drives I have access to).
While I'm there correct a few typos.

- always call config_found() from wdcattach(), instead of printing our own
  the "not configured" message ourselve. When no atapibus is configured,
  use a fake ata_atapi_attach, else call wdc_atapibus_attach(). This way we
  don't have to include the whole atapi support in an ata-only config.
- the dma_* function pointers take a 'int flags' as last argument, instead
  of an 'int read'. The 2 valid flags are: WDC_DMA_READ (to select read/write)
  and WDC_DMA_POLL, to signal interrupt-less mode (for core dumps).
- Reworked wdcprobe() so look more like the old one. A status of 0xff is
  interpreted as "no drive" (freebsd does this); this this speed up
  the probe for non-IDE machines (a reset timeout has been bumped to 31s,
  to match the specs). The probe set ups the drive flags to either ATA or
  ATAPI (depend on register signature) or OLD (if register signature don't
  match, but a working drive appears to be there). Later the ATA code
  will look at the OLD flag to decide wether there is no drive, or an old
  (ST506) one if WDC_IDENTIFY fails.
- For known PCI chips, don't use the wdcprobe() heuristic to find wether
  a channel is enabled/disabled; use the chip's specific registers for this.
- Clear the command queue when we have a polled command. This allows dumps to
  work even if a command was being handled by the controller at panic time.
- Increase the number of available DMA segments by one, as user requests may
  not be aligned on a page boundary.
