d03048e853 Fix a typo that resulted in or-ing PTE_UW twice whrn PTE_SW was needed.
Note that setting the PTE_MODIFIED bit based on whether write is possible
is incorrect. We should set PTE_MODIFIED based on whether the access
is a write operation.

53224f018a Extend the KPI to lock and unlock f_offset member of struct file. It
now fully encapsulates all accesses to f_offset, and extends f_offset
locking to other consumers that need it, in particular, to lseek() and
variants of getdirentries().

Ensure that on 32bit architectures f_offset, which is 64bit quantity,
always read and written under the mtxpool protection. This fixes
apparently easy to trigger race when parallel lseek()s or lseek() and
read/write could destroy file offset.

The already broken ABI emulations, including iBCS and SysV, are not
converted (yet).

abb8277b31 Cosmetic display change of Cx states via cx_supported sysctl entries.
Adjust power_profile script to handle the new world order as well.

Some vendors are opting out of a C2 state and only defining C1 & C3.  This
leads the acpi_cpu display to indicate that the machine supports C1 & C2
which is caused by the (mis)use of the index of the cx_state array as the
ACPI_STATE_CX value.

e.g. the code was pretending that cx_state[i] would
always convert to i by subtracting 1.

cx_state[2] == ACPI_STATE_C3
cx_state[1] == ACPI_STATE_C2
cx_state[0] == ACPI_STATE_C1

however, on certain machines this would lead to
cx_state[1] == ACPI_STATE_C3
cx_state[0] == ACPI_STATE_C1

This didn't break anything but led to a display of:
 * dev.cpu.0.cx_supported: C1/1 C2/96

Instead of
 * dev.cpu.0.cx_supported: C1/1 C3/96

1610fb0c22 Add acpi_asus_wmi(4) -- driver for random extras found on WMI-compatible
Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead
of separate ACPI device.

On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN,
Bluetooth, LCD backlight, camera, cardreader and touchpad.

On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth,
Wireless LED, control keyboard backlight brightness, monitor temperature
and fan speed. LCD brightness control doesn't work now for unknown reason,

2c2512f3df For the ports modules building code, clean WRKDIR before building. This is
important for those that use -DNO_CLEAN routinely, since it will prevent
installing stale stuff, and even more important when the port is upgraded
to a newer version. When the user doesn't use -DNO_CLEAN, this will create
an infinitesimal amount of extra work, but won't hurt anything.

This is necessary because the ports tree has flags that prevent the ususal
'update the build if newer source files exist' logic from doing what it
would do in the base.

1e8cef649c ctype_l(3): Note that not all these functions are specified by POSIX.1-2008.
The function isascii_l() is not in POSIX even though isascii() is,
probably because isascii() is marked as obsolete.  The other functions,
like digittoint_l() and ishexnumber_l(), are FreeBSD-specific just like
their non-_l versions.

1a62bb3224 Make geom_mirror more friendly to SSDs. To properly support TRIM,
we need to pass BIO_DELETE requests down to providers that support
it. Also, we need to announce our support for BIO_DELETE to upper
consumer. This requires:

- In g_mirror_start() return true for "GEOM::candelete" request.
- In g_mirror_init_disk() probe below provider for "GEOM::candelete"
  attribute, and mark disk with a flag if it does support BIO_DELETE.
- In g_mirror_register_request() distribute BIO_DELETE requests only
  to those disks, that do support it.

Note that we announce "GEOM::candelete" as true unconditionally of
whether we have TRIM-capable media down below or not. This is made
intentionally, because upper consumer (usually UFS) requests the
attribite only once at mount time. And if user ever migrates his
mirror from HDDs to SSDs, then he/she would get TRIM working without
remounting filesystem.
