Rollback http://mail-index.netbsd.org/source-changes/2018/12/22/msg101629.html

This change breaks module loading due to weak alias being unsupported
in the kernel module linker.

Requested by maxv@ and others as it affects their work.

No immediate decision on a replacement method is available, but other options
suggested include pre-processing, conditional compilation (#ifdef etc) and other
source level methods to avoid linktime decision making.

Introduce a weak alias method of exporting different implementations
of the same API.

For eg: the amd64 native implementation of invlpg() now becomes
amd64_invlpg() with a weak symbol export of invlpg(), while the XEN
implementation becomes xen_invlpg(), also weakly exported as invlpg()

Note that linking in both together without having an override function
named invlpg() would be a mistake, as we have limited control over
which of the two options would emerge as the finally exported invlpg()
resulting in a potential situation where the wrong function is finally
exported. This change avoids this situation.

We should however include an override function invlpg() in that case,
such that it is able to then pass on the call to the appropriate
backing function (amd64_invlpg() in the case of native, and
xen_invlpg() in the case of under XEN virtualisation) at runtime.

This change does not introduce such a function and therefore does not
alter builds to include native as well as XEN implementations in the
same binary. This will be done later, with the introduction of XEN
PVHVM mode, where precisely such a runtime switch is required.

There are no operational changes introduced by this change.

Add accessors for available x86 Debug Registers

There are 8 Debug Registers on i386 (available at least since 80386) and 16
on AMD64. Currently DR4 and DR5 are reserved on both cpu-families and
DR9-DR15 are still reserved on AMD64. Therefore add accessors for DR0-DR3,
DR6-DR7 for all ports.

Debug Registers x86:
 * DR0-DR3  Debug Address Registers
 * DR4-DR5  Reserved
 * DR6      Debug Status Register
 * DR7      Debug Control Register
 * DR8-DR15 Reserved

Access the registers is available only from a kernel (ring 0) as there is
needed top protected access. For this reason there is need to use special
XEN functions to get and set the registers in the XEN3 kernels.

XEN specific functions as defined in NetBSD:
 - HYPERVISOR_get_debugreg()
 - HYPERVISOR_set_debugreg()

This code extends the existing rdr6() and ldr6() accessor for additional:
 - rdr0() & ldr0()
 - rdr1() & ldr1()
 - rdr2() & ldr2()
 - rdr3() & ldr3()
 - rdr7() & ldr7()

Traditionally accessors for DR6 were passing vaddr_t argument, while it's
appropriate type for DR0-DR3, DR6-DR7 should be using u_long, however it's
not a big deal. The resulting functionality should be equivalent so stick
to this convention and use the vaddr_t type for all DR accessors.

There was already a function defined for rdr6() in XEN, but it had a nit on
AMD64 as it was casting HYPERVISOR_get_debugreg() to u_int (32-bit on
AMD64), truncating result. It still works for DR6, but for the sake of
simplicity always return full 64-bit value.

New accessors duplicate functionality of the dr0() function available on
i386 within the KSTACK_CHECK_DR0 option. dr0() is a specialized layer with
logic to set appropriate types of interrupts, now accessors are designed to
pass verbatim values from user-land (with simple sanity checks in the
kernel). At the moment there are no plans to make possible to coexist
KSTACK_CHECK_DR0 with debug registers for user applications (debuggers).

     options KSTACK_CHECK_DR0
     Detect kernel stack overflow using DR0 register.  This option uses DR0
     register exclusively so you can't use DR0 register for other purpose
     (e.g., hardware breakpoint) if you turn this on.

The KSTACK_CHECK_DR0 functionality was designed for i386 and never ported
to amd64.

Code tested on i386 and amd64 with kernels: GENERIC, XEN3_DOMU, XEN3_DOM0.

Catchup with rmind-uvmplock merge.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

- Fix tlbflushg() to behave like tlbflush(), if page global extension (PGE)
  is not (yet) enabled.  This fixes the issue of stale TLB entry, experienced
  early on boot, when PGE is not yet set on primary CPU.
- Rewrite i386/amd64 TLB interrupt handlers in C (only stubs are in assembly),
  which simplifies and unifies (under x86) code, plus fixes few bugs.
- cpu_attach: remove assignment to cpus_running, as primary CPU might not be
  attached first, which causes reset (and thus missed secondary CPUs).

Improve x86 tsc handling:

- Ditch the cross-CPU calibration stuff. It didn't work properly, and it's
  near impossible to synchronize the CPUs in a running system, because bus
  traffic will interfere with any calibration attempt, messing up the
  timings.

- Only enable the TSC on CPUs where we are sure it does not drift. If we are
  On a known good CPU, give the TSC high timecounter quality, making it the
  default.

- When booting CPUs, detect TSC skew and account for it. Most Intel MP
  systems have synchronized counters, but that need not be true if the
  system has a complicated bus structure. As far as I know, AMD systems
  do not have synchronized TSCs and so we need to handle skew.

- While an AP is waiting to be set running, try and make the TSC drift by
  entering a reduced power state. If we detect drift, ensure that the TSC
  does not get a high timecounter quality. This should not happen and is
  only for safety.

- Make cpu_counter() stuff LKM safe.

x86 changes for pcc and LKMs.

- Replace most inline assembly with proper functions. As a side effect
  this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
  smaller amount. Nearly all of the inlines did something slow, or something
  that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
  In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.
