e99c09e2dc Eliminate global cons_unavailable flag and replace it by the status 
bit maintained on a per-device basis. Single variable is inadequate
on machines running with multiple consoles enabled.

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.)

3db6450423 Reconfigure the runq macros to use the 64 bit ffs/bsf routines instead 
of doing a loop and taking two 32 bit passes at the runqueue bits.  All
the 64 bit platforms should probably do this since there are 64 run queues.

42f5377536 Revert some amd64 changes that cached curthread and converge back to the 
i386 version.  The curthread special case in pcpu.h solves my complaint
about the verbose macro expansion in this case.  Note that the i386
version still has some OBE comments, I didn't re-add them back again.
