Will be touching many of these files soon for functional changes.
No functional change intended.

It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.
So there's no need to issue explicit barriers here. The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.

atomic_cas_ulong().
- For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own
MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent
(atomic_cas_uint() on m68k).
- For alpha and sparc64, don't define MUTEX_CAS() in terms of their own
_lock_cas(), which has its own memory barriers; the call sites in
kern_mutex.c already have the appropriate memory barrier calls. Thus,
alpha and sparc64 can use default definition.
- For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas();
atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining
our own MUTEX_CAS() is redundant.

Protect __lwp_getprivate_fast() with _RTLD_SOURCE, _LIBC_SOURCE and
__LIBPTHREAD_SOURCE__.
Include in this namespace <sys/tcl.h> and use __BEGIN_DECLS/__END_DECLS
for the sake of consistency.

ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().
XXX ARM and IA64 implementations of acpi_md_intr_mask() and
acpi_md_intr_unmask() are just stubs for now.

This was a very nice win in my tests on a 48 CPU box.
- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
the IPI bitmask and ci_want_resched.

This was full of definitions that have been obsolete for over a
decade. The file still remains for __HAVE_RW_STUBS but that's all.
Used only internally in kern_rwlock.c now, not by <sys/rwlock.h>.

- Remove all code that should be MI, leaving the bare minimum under arch/.
- Make the required actions very explicit.
- Pass in LWP pointer for convenience.
- When a trap is required on another CPU, have the IPI set it locally.
- Expunge cpu_did_resched().

The macro is dummy for ia64 (the FP register is unknown and can change
freely) and sparc/sparc64 (not stored in struct reg).

Stop mapping _UC_MACHINE_FP() to a register as it is not supported by CPU.
There is need to use in code __builtin_frame_address() inlined in the code
to get the frame pointer.
Return a constant value 0 instead. New value does not pretend to return
a meaningful value.
While there, fix the definition of _UC_MACHINE_SET_PC as it didn't contain
the pc argument in the definition.

also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports
have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3
have lower MAXPHYS)

- For UAREA, arrange layout same as FreeBSD for now to hopefully
ease porting woes. add some related macros
locore.S is incorrectly assuming same layout and seems painful
to change bspstore in startup
- use ia64_init_return same as FreeBSD
- change some "printf" to "panic" for incompleted items
context switching is still broken but maybe less so

This change:
* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.
* Removes the PMC code of ARM XSCALE.
* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.
* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.
* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.
* Removes the pmc_evid_t and pmc_ctr_t types.
* Removes all the associated man pages. The sets are marked as obsolete.

AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".
Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.
Proposed on tech-kern@ on Dec 29.
