Allow the alarm hours/mins/seconds registers to be read/written,
though without any action. This avoids a hypervisor exit when
o/s's access these regs (Linux).
Fix several problems in the new iSCSI stack; this includes interoperability
fix for LIO (Linux target), removing possibility for the target to avoid mutual
CHAP by choosing to skip authentication altogether, and fixing truncated error
messages in iscsictl(8) output. This also fixes several of the problems found
with Coverity.
Fix panic in ktrcapfail() when no capability rights are passed.
While here, correct all consumers to pass NULL instead of 0 as we pass
capability rights as pointers now, not uint64_t.

Implement epoll support in Linuxulator. This is a tiny wrapper around kqueue
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.

Fix 'make installcheck' to check for missing UID/GID as well, broken
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 _.

Disallow cap_enter() in freebsd32 compatibility mode.
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.
Merge in support for PAPR-compliant (Power Architecture Platform
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.
Fix a bug in decoding an instruction that has an SIB byte as well as an
immediate operand. The presence of an SIB byte in decoding the ModR/M field
would cause 'imm_bytes' to not be set to the correct value.
Fix this by initializing 'imm_bytes' independent of the ModR/M decoding.
Add a loader tunable to use only device tree-provided PCI devices. This is
needed on some more fragile systems to avoid machine checks when blindly
probing the PCI bus. Also reduce ofw_pcibus's priority slightly so that it
can be overridden.
Fix bug in busdma: if segs is a preexisting buffer, we memcpy it
into the DMA map. The length of the buffer had not yet been
initialized, however, so this would copy gibberish unless it
happened to be right by chance. This bug mostly only affected
systems with IOMMUs.

Write protect base page after superpage demotion so that it may repromote
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.
Remove zero-copy sockets code. It only worked for anonymous memory,

Remove the cow member of struct vm_page, and rearrange the remaining

In pmap_copy(), when the copied region is mapped with superpage but does
not cover entire superpage, avoid copying. Doing partial copy would
require demotion, which is incompatible with the already held locks.

Use the address of the inpcb rather than the tcpcb to identify TCP
connections. This keeps the tcp provider consistent with the other network
providers.
Add a kernel interface (OF_xref_phandle()) for systems where phandles
used as cross-references in the device tree and phandles as used by the
Open Firmware client interface are in different namespaces. This include
IBM pSeries hardware as well as FDT systems. FDT certainly abuses
ihandles for this purpose and should be modified to use this API
eventually. This changes no behavior on systems where FreeBSD already
worked.

Properly remove c++filt.
The c++filt binary is only installed if ${MK_GCC} == yes && ${MK_CXX} ==
yes. This means that it should be removed if ${MK_GCC} == no ||
${MK_CXX} == no. In its current form, it actually uses a conjunction
instead of a disjunction.
As there is already a separate block for ${MK_CXX} == no listing
c++filt, simply remove the conditional entirely.
drm/radeon: Fix usage of pci_save_state() and pci_restore_state()
Calling those functions with the drmn device as argument causes a panic,
because it's not a direct child of pci$N. They must be called with the
vgapci device instead.
This fix is not enough to make suspend/resume work reliably.
vga_pci_(un)map_bios() takes a vgapci device as argument, not a drmn
one. This fixes a bug where the BIOS couldn't be mapped if the device
wasn't the boot display.

If the last page of the file is partially full and whole valid
portion is invalidated, invalidate the whole page. Otherwise,
partially valid page appears on a page queue, which is wrong. This
could only happen for the last page, because only then buffer which
triggered invalidation could not cover the whole page.
