x86: Split most of pmap.h into pmap_private.h or vmparam.h.
This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.
Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:
1. CPU-specific (different for i386/amd64) definitions used by...
2. common definitions, including Xenisms like xpmap_ptetomach,
further used by...
3. more CPU-specific inlines for pmap_pte_* operations
So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3. Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.
No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.
Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:
VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS
Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

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.

Diff to previous 1.22 (colored)
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.

Fix for i386, functionality intended in: http://mail-index.netbsd.org/source-changes/2018/09/23/msg099357.html This should fix the build for both GENERIC and XEN3PAE_DOM0 This has not been boot tested on native or xen3pae Notes: pmap_changeprot_local() seems to be x86_64 only. I was a bit surprised by this initially, but I suspect that the table protections are enforced via ring0/ring1 fencing rather than page protections the gdt registration code in i386 is still messy. I will leave it as is for now - to avoid a rabbit hole.

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.

Welcome PAE inside i386 current.
This patch is inspired by work previously done by Jeremy Morse, ported by me
to -current, merged with the work previously done for port-xen, together with
additionals fixes and improvements.
PAE option is disabled by default in GENERIC (but will be enabled in ALL in
the next few days).
In quick, PAE switches the CPU to a mode where physical addresses become
36 bits (64 GiB). Virtual address space remains at 32 bits (4 GiB). To cope
with the increased size of the physical address, they are manipulated as
64 bits variables by kernel and MMU.
When supported by the CPU, it also allows the use of the NX/XD bit that
provides no-execution right enforcement on a per physical page basis.
Notes:
- reworked locore.S
- introduce cpu_load_pmap(), used to switch pmap for the curcpu. Due to the
different handling of pmap mappings with PAE vs !PAE, Xen vs native, details
are hidden within this function. This helps calling it from assembly,
as some features, like BIOS calls, switch to pmap_kernel before mapping
trampoline code in low memory.
- some changes in bioscall and kvm86_call, to reflect the above.
- the L3 is "pinned" per-CPU, and is only manipulated by a
reduced set of functions within pmap. To track the L3, I added two
elements to struct cpu_info, namely ci_l3_pdirpa (PA of the L3), and
ci_l3_pdir (the L3 VA). Rest of the code considers that it runs "just
like" a normal i386, except that the L2 is 4 pages long (PTP_LEVELS is
still 2).
- similar to the ci_pae_l3_pdir{,pa} variables, amd64's xen_current_user_pgd
becomes an element of cpu_info (slowly paving the way for MP world).
- bootinfo_source struct declaration is modified, to cope with paddr_t size
change with PAE (it is not correct to assume that bs_addr is a paddr_t when
compiled with PAE - it should remain 32 bits). bs_addrs is now a
void * array (in bootloader's code under i386/stand/, the bs_addrs
is a physaddr_t, which is an unsigned long).
- fixes in multiboot code (same reason as bootinfo): paddr_t size
change. I used Elf32_* types, use RELOC() where necessary, and move the
memcpy() functions out of the if/else if (I do not expect sym and str tables
to overlap with ELF).
- 64 bits atomic functions for pmap
- all pmap_pdirpa access are now done through the pmap_pdirpa macro. It
hides the L3/L2 stuff from PAE, as well as the pm_pdirpa change in
struct pmap (it now becomes a PDP_SIZE array, with or without PAE).
- manipulation of recursive mappings ( PDIR_SLOT_{,A}PTEs ) is done via
loops on PDP_SIZE.
See also http://mail-index.netbsd.org/port-i386/2010/07/17/msg002062.html
No objection raised on port-i386@ and port-xen@R for about a week.
XXX kvm(3) will be fixed in another patch to properly handle both PAE and !PAE
kernel dumps (VA => PA macros are slightly different, and need proper 64 bits
PA support in kvm_i386).
XXX Mixing PAE and !PAE modules may lead to unwanted/unexpected results. This
cannot be solved easily, and needs lots of thinking before being declared
safe (paddr_t/bus_addr_t size handling, PD/PT macros abstractions).

Starting with Xen 3 API, MMU_EXTENDED_COMMAND (tlb flush, cache flush, page pinning/unpinning, set_ldt, invlpg) operations cannot be queued in the xpq_queue[] any more, as they use their own specific hypercall, mmuext_op(). Their associated xpq_queue_*() functions already call xpq_flush_queue() before issuing the mmuext_op() hypercall, which makes these xpq_flush_queue() calls not necessary. Rapidly discussed with bouyer@ in private mail. XEN3_DOM0/XEN3PAE_DOM0 tested through a build.sh release, amd64 was only compile tested. No regression expected.

Prepare for xenamd64: - kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few #ifndef XEN) - move some files that can be shared between i386 and amd64 from xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code) - split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h - use <xen/...> instead of <machine/...> for cpu-independant include files. more work needed here, i386-specific files should got out of arch/xen to arch/xeni386, and more code shared with arch/i386.
