4fd76feafd Fix accounting for hw.realmem on the i386 and amd64 platforms.
sys/i386/i386/machdep.c:
sys/amd64/amd64/machdep.c:
	The value reported by FreeBSD as "real memory" when booting
	doesn't match what is later reported by sysctl as hw.realmem.
	This is due to the fact that the value printed during the
	boot process is fetched from smbios data (when possible),
	and accounts for holes in physical memory. On the other
	hand, the value of hw.realmem is unconditionally set to be
	one larger than the highest page of the physical address
	space.

	Fix this by setting hw.realmem to the same value printed
	during boot, this makes hw.realmem honour it's name and
	account properly for physical memory present in the system.

2191c4bafb - Move CAP_EXTATTR_* and CAP_ACL_* rights to index 1 to have more room
in index 0 for the future.
- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
  CAP_LOOKUP right in them.
- Shuffle the bits around so there are no gaps. This is last chance to do
  that as all moved rights are not used yet.

d8f7bfb8bd The previous code makes a memory allocation in size of
struct mbx_common_read_write_flashrom plus 32KB and caps the actual
transfer size at 32KB.  This is harmless as it is but may confuse
static code analyzer, so allocate a full 32KB instead.

e5056f9882 Introduce allocation cache to store LZ4 compression contexts without kicking
VM subsystem twice for every written record.

Tests on 24-core system show double reduction of CPU time spent on copying
single large well-compressed file.

This patch is not really needed on illumos (while not harm either) since
their memory allocator by default uses caching for all requests up to 128K.

3d271aaab0 x86: Allow users to change PSL_RF via ptrace(PT_SETREGS...)
Debuggers may need to change PSL_RF.  Note that tf_eflags is already stored
in the signal context during signal handling and PSL_RF previously could be
modified via sigreturn, so this change should not provide any new ability
to userspace.

- close cosmetic race in svc_exit();
 - do not set wait timeout for idle threads if we have no use for wakeups;
 - create new requested thread sooner, not only after some another thread
wakeup, that may happen later under constant load.

6fcfd7ab4e When verifying that files we need are present, also check that they don't
have zero length.  Filesystem corruption will tend to truncate files, and
since these are short that's likely to result in them becoming empty.

6171f42c9f Fix (I think!) the scan timeouts on the intel NICs.
This field needs to be (a) set, and (b) greater than the other timeouts
(passive, active, maxquiet, etc.)  It also is in microseconds, not
milliseconds.

I hope this will fix the scan hangs that people are seeing.

20dc9c67c4 Since the doc/ toolchain conversion to docbook 5.0, JADETEX
is no longer a valid option, so remove 'WITHOUT_JADETEX=yes'
from PBUILD_FLAGS.

While here, also remove 'WITHOUT_X11=yes', since it will
cause a dependency conflict by requiring both print/ghostscript9
and print/ghostscript9-nox11.

Switch to OPTIONSNG format (WITHOUT_* -> OPTIONS_UNSET='FOO'),
and unset the FOP option, which requires Java (although it is
disabled by default).  Also unset the 'IGOR' option, since
textproc/igor is a validation tool, not necessarily a dependency
of the doc/ build itself.

While here, reduce the line length of PBUILD_FLAGS.
