allow pcu_save() and pcu_discard() to be called on other threads,
ptrace needs to use it that way.

KNF

Rebase to HEAD as of a few days ago.

Add __NO_FIQ to prevent testing of the PSR FIQ bit
Use VALID_R15_PSR(pc, spsr) instead of testing explicitly

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

sync with head

Merge armv7 support from HEAD, specifically support for the BCM5301X
and BCM56340 evbarm kernels.

Remove __HAVE_PROCESS_XFPREGS and add the extra parameter for the size
  of the fp save area to all the process_read_fpregs() and
  process_write_fpregs() functions.
None of the functions have been modified to use the new parameters.
The size is set for all the writes, but some of the arch-specific reads
  just pass NULL.
The amd64 (and i386) need variable sized fp register save areas in order
  to support AVX and other enhanced register areas.
These functions are rarely called - so the extra argument won't matter.

Fix size parameter to memset. Found by gcc 4.8.

sync with head

Reap LWP_VFPUSED and use PCU internal tracking.
Add bool vfp_used_p(void);

Move parts of cpu.h that are not needed by MI code in <arm/locore.h>
Don't include <machine/cpu.h> or <machine/frame.h>, use <arm/locore.h>
Use <arm/asm.h> instead of <machine/arm.h>

Make sure the enable bit is not set when restoring the VFP context since
that has special meaning to the VFP PCU code.

ARMFPE hasn't compiled since NetBSD 4.  Remove it.
Complete support for FPU_VFP.
fpregs now contains vfpreg.
XXX vfpreg only has space for 16 64-bit FP registers though VFPv3 and later
have 32 64-bit FP registers.

Merge improved arm support (especially Cortex) from HEAD
including OMAP and BCM53xx support.

Rename process_frame to lwp_trapframe

sync with head

Use lwp_getpcb() on ARM (and acorn26/32), clean from struct user usage.

KNF, same object code generated.

Commit is split, to avoid a "too many arguments" protocol error.

Update haad-dm branch to haad-dm-base2.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

Now that process_frame() is a macro (done "unannounced" in arm's
include/frame.h), don't try to define an inline function with the
same name and same contents.

Drop redundant (and wrong) cast.

Declare the second arg of process_write_{fp,}regs() to be const.
This permits sh5 to continue to re-use those functions in cpu_setmcontext()
with the recent change to Makefile.kern.inc (revision 1.62).

Fix the sync with head I botched.

Fix Frank Lancaster's broken license (after consulting with him).
Pointed out by wiz.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Merge the nathanw_sa branch.

No longer need to pull in lwp.h; proc.h pulls it in for us.

Sync kqueue branch with -current.

Catch up to -current.

Move the ARM, Ltd. floating point emulator to arch/arm.

Add 26-bit and 32-bit types.h files, which indicate the programming
model in use for a given platform (__PROG26 vs __PROG32), then pulls
in <arm/types.h>.  Change each ARM port to pull in <arm/arm26/types.h>
or <arm/arm32/types.h> as appropriate.  Change all references to PROG26
and PROG32 to __PROG26 and __PROG32.  Eliminate the opt_progmode.h
header file.

Machine-dependent kernel mods for scheduler activations on
32-bit ARM processors.  Kernel boots multi-user on an XScale,
but upcalls not yet tested.

Sync the thorpej-mips-cache branch with -current.

PCB convergence, part the first:
Move the pointer to the current user trapframe from struct mdproc to struct
pcb (as on arm26).  Only tested by compiling kernels on arm32 and
hpcarm (dnard seems to be incomplete anyway).  Someone should try running one.

opt_armfpe.h isn't arm32-specific any more.

<arm/armreg.h> isn't arm26-specific any more.

Stop using #ifdef arm32, since future NetBSD/arm ports are likely
not to provide it.

For things which are historical oddities of NetBSD/arm26, use #ifndef arm26.
For things which are inherently dependent on the size of program space in use,
use #ifdef PROG32 (and include opt_progmode.h).

This file doesn't need <machine/cpus.h>.

Shared ARM ptrace(2) implementation.  Mostly the same as the arm32
version, but with some #ifdefs for arm26.

Also, don't define PT_STEP, since we don't implement it.  This should
reduce code size a little.
