937f5a8e02 Since we don't use PG_NX yet, don't turn on EFER_NXE quite yet. This needs 
to be done based on the cpuid bits.  AMD says that we should test the cpuid
features bits for certain things, such as this.

dc08ffec87 Device megapatch 4/6: 
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

5162123068 Remove the badsw* INVARIANTS checks. The events that this attempts 
to catch are already nicely caught by trapping the null pointer derefs.
Remove no-longer-used noswitch/nothrow strings.  They were referenced
by the stub cpu_switch() etc functions before they were implemented.
Try something a little different for the lock prefixes.

Prompted by:  bde (the first two items anyway)

048ac395be - Recruit some new ULE users by making it the default scheduler in GENERIC. 
ULE will be in a probationary period to determine whether it will be left
   as the default in 5.3 which would likely mean the rest of the 5.x series.

e4dc8baa84 Provide sysarch(2) prototypes in the MD sysarch.h headers. While I'm 
at it, use the ANSI C generic pointer type for the second argument,
thus matching the documentation.

Remove the now extraneous (and now conflicting) function declarations
in various libc sources.  Remove now unnecessary casts.

a30ec4b99c Make sigaltstack as per-threaded, because per-process sigaltstack state 
is useless for threaded programs, multiple threads can not share same
stack.
The alternative signal stack is private for thread, no lock is needed,
the orignal P_ALTSTACK is now moved into td_pflags and renamed to
TDP_ALTSTACK.
For single thread or Linux clone() based threaded program, there is no
semantic changed, because those programs only have one kernel thread
in every process.

f79f3abcbf - Use pagezero() instead of bzero() in pmap_pinit(). (pagezero() is much 
faster.)
MFi386:
 - Don't bother clearing PG_ZERO on the page table page in
   _pmap_allocpte(); it serves no purpose.
 - Don't bother clearing and setting PG_BUSY on page table directory pages.

925692caa5 - Significantly reduce the number of preallocated pv entries in 
pmap_init().  Such a large preallocation is unnecessary and wastes
   nearly eight megabytes of kernel virtual address space per gigabyte
   of managed physical memory.
 - Increase UMA_BOOT_PAGES by two.  This enables the removal of
   pmap_pv_allocf().  (Note: this function was only used during
   initialization, specifically, after pmap_init() but before
   pmap_init2().  During pmap_init2(), a new allocator is installed.)

such that 'ispcvt' can build.  Unforunately 'ispcvt' is needed in order for
/etc/rc.d/syscons to run.  This fixes the bug where I could not get my
keymap effective at boot.
