This adopts the same change as r291936 for UFS.
Directly clear IN_ACCESS or IN_UPDATE when user supplied the time, and
copy the value into the inode.
This keeps the behaviour cleaner and is consistent with UFS.

or pte-v6.h in files which needs it.
There are quite internal definitions in pte-v4.h and pte-v6.h headers
specific for corresponding pmap implementation. These headers should be
included only in very few files and an intention is to not hide for
which implementation such files are.
Further, sys/arm/arm/elf_trampoline.c is an example of file which
uses armv4 like pmap implementation for both armv4 and armv6 platforms.
This is another reason why pte.h which includes specific header
according to __ARM_ARCH is not created.
Create new pmap.h which includes specific header according to
__ARM_ARCH.
Note that <machine/pmap.h> is included from <vm/pmap.h> so one common
<machine/pmap.h> must exist.
- Add definitions for Timing Advertisement and Control Wrapper frames.
- Refresh ieee80211_mgt_subtype_name and ieee80211_ctl_subtype_name
arrays.
- Count Timing Advertisement frames as discarded management frames in all
modes.

r274560 modified kqueue_register() to only test the event condition if the
corresponding knote is not disabled. However, this check takes place before
the EV_ENABLE flag is used to clear the KN_DISABLED flag on the knote, so
enabling a previously-disabled kevent would not result in a notification for
a triggered event. This change fixes the problem by testing for EV_ENABLED
before possibly checking the event condition.
This change also updates a kqueue regression test to exercise this case.

This also uses a trick suggested by sjg@ to still read them in when

edit in the future could cause problems (though given the nature of
this specific code, the problems quite likely would be some variation
of "most direct access SCSI storage devices won't attach," which is
unlikely to go unnoticed).

Import portions of the PowerPC OF PCI implementation into
new file "ofw_pci.c", common for other platforms. The files ofw_pci.c and
ofw_pci.h from sys/powerpc/ofw no longer exist. All required declarations
are moved to sys/dev/ofw/ofw_pci.h.
This creates a new ofw_pci_write_ivar() function and modifies
ofw_pci_nranges(), ofw_pci_read_ivar(), ofw_pci_route_interrupt() methods.
Most functions contain existing ppc implementations in the majority
unchanged. Now there is no need to have multiple identical copies
of methods for various architectures.

Provide bus_get_bus_tag() for sparc64, powerpc, arm, arm64 and mips
nexus and its children in order to return a platform specific default tag.
This is required to ensure generic correctness of the bus_space tag.
It is especially needed for arches where child bus tag does not match
the parent bus tag. This solves the problem with ppc architecture
where the PCI bus tag differs from parent bus tag which is big-endian.
This commit is a part of the following patch:

as noted by royger.
Old spinlock based txdesc list is still kept around, so we could have
a safe fallback.
