Fix the x86 instruction decoder to decode bsr/bsf/jmpe with
operand-size prefix (66h). This fixes the test case failure
reported by Linus, attached below.
bsf/bsr/jmpe have a special encoding. Opcode map in
Intel Software Developers Manual vol2 says they have
TZCNT/LZCNT variants if it has F3h prefix. However, there
is no information if it has other 66h or F2h prefixes.
Current instruction decoder supposes that those are
bad instructions, but it actually accepts at least
operand-size prefixes.
H. Peter Anvin further explains:
" TZCNT/LZCNT are F3 + BSF/BSR exactly because the F2 and
F3 prefixes have historically been no-ops with most instructions.
This allows software to unconditionally use the prefixed versions
and get TZCNT/LZCNT on the processors that have them if they don't
care about the difference. "

Linus reported that due to mac80211 failing to register
the device (due to WoWLAN) his machine crashed etc. as
we double-freed the vmalloc() firmware area. His patch
to fix it was very similar to this one but I noticed
that there's another bug in the area: we complete the
completion before starting, so since we're running in
a work struct context stop() could be called while in
the middle of start() which will almost certainly lead
to issues.
Make a modification similar to his to avoid the double-
free but also move the completion to another spot so it
is only done after start() either finished or failed so
that stop() can have a consistent state.

The open recovery code does not need to request a new value for the

The problem is that encode_getfattr_open() will still request an
mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold.
This patch fixes encode_getfattr_open so that it doesn't request an
mdsthreshold when the caller isn't asking for one. It also fixes
decode_attr_mdsthreshold so that it errors if the server returns
an mdsthreshold that we didn't ask for (instead of Oopsing).

The commit (bce492c0 ARM: OMAP2+: UART: Fix incorrect population of
default uart pads) removed default uart pads that where getting populated
and which was making rx pin wakeup capable. If uart pads were used in
different mode by any other module then it would fail since the default
pads took over all the uart pins forcefully. With removal of default pads
the rx_pad wakeup for console uart while waking up from off mode is broken.
Utilise the mux api available to probe the availability of mux pins
in uart mode and probe for availability of uart pin in mux mode0
if uart is available as uart pin itself then configure rx pin
as wakeup capable.
This patch itself doesn't cater to all boards. Boards using uart rx wakeup
mechanism should ensure the usage of omap_serial_init_port by configuring
required uart ports and pass necessary mux data, till then this probing of
uart pins can cater to enabling of rx pad wakeup to most of the boards.
This patch can also throw some boot warning from _omap_mux_get_by_name
if pin is requested for availability is not present while dynamically probing
the uart pins availability such boot warnings can be addressed only when board
files are patched with omap_serial_init_port calls passing the right pads
needed for a given port.
