While here, correct all consumers to pass NULL instead of 0 as we pass
capability rights as pointers now, not uint64_t.

to implement epoll subset of functionality. The kqueue user data are 32bit
on i386 which is not enough for epoll user data so this patch overrides
kqueue fileops to maintain enough space in struct file.
Initial patch developed by me in 2007 and then extended and finished
by Yuri Victorovich.

since r249893, by adding a separate _installcheck_world and
_installcheck_kernel so the destination targets can be more explicit
on which they are needed for.
installcheck will call both, while installworld only calls
_installcheck_world and installkernel only calls _installcheck_kernel
While here, mark the internal targets as starting with _.

The freebsd32 compatibility mode (for running 32-bit binaries on 64-bit
kernels) does not currently allow any system calls in capability mode, but
still permits cap_enter(). As a result, 32-bit binaries on 64-bit kernels
that use capability mode do not work (they crash after being disallowed to
call sys_exit()). Affected binaries include dhclient and uniq. The latter's
crashes cause obscure build failures.
This commit makes freebsd32 cap_enter() fail with [ENOSYS], as if capability
mode was not compiled in. Applications deal with this by doing their work
without capability mode.
This commit does not fix the uncommon situation where a 64-bit process
enters capability mode and then executes a 32-bit binary using fexecve().
This commit should be reverted when allowing the necessary freebsd32 system
calls in capability mode.

Since iconv was enabled (r254273, August 13), it has been impossible to
installworld using a read-only obj tree. This is common with NFS. Parts of
share/i18n unconditionally rebuild files like mapper.dir during
installation.
This patch ensures the files like mapper.dir are not rewritten with the same
contents.

Requirements) systems from the projects/pseries branch. This in principle
includes all IBM POWER hardware released in the last 15 years with the
exception of POWER3-based systems when run in 64-bit mode. The main
development target, however, has been the PAPR logical partition support
that is the default target in KVM on POWER and QEMU -- mileage may vary
on actual hardware at present. Much of the heavy lifting here was done
by Andreas Tobler.

would cause 'imm_bytes' to not be set to the correct value.
Fix this by initializing 'imm_bytes' independent of the ModR/M decoding.

When clearing the modification status of the superpage, one of the
base pages produced during demotion should be marked as write disabled.
The intention is that subsequent write access may repromote.
In the current implementation this was done wrong as write permission was
granted instead of forbidden.
