The test was backwards, triggering IRQ autoprobing if the firmware
did not specify an IRQ, instead of triggering it only when the
module force parameter was specified.
Since autoprobing is not enabled on !x86 and the platform device is
currently only used on !x86, or with force, this has gone unnoticed.

In preparation of the modifications to tpm_pcr_extend(), which will
allow callers to supply a digest for each PCR bank of a TPM 2.0,
the TPM 1.2 specific code has been moved to tpm1_pcr_extend().
tpm1_pcr_extend() uses tpm_buf_init() to prepare the command buffer,
which offers protection against buffer overflow. It is called by
tpm_pcr_extend() and tpm_pm_suspend().

In the long term, TPM 1.2 functions in the driver interface will be
modified to use tpm_buf_init().
However, tag and ordinals cannot be passed directly to tpm_buf_init(),
because this function performs CPU native to big-endian conversion of these
arguments. Since TPM_TAG_RQU_COMMAND and TPM_ORD_ are already converted,
passing them to the function will undo the previous conversion.
This patch moves the conversion of TPM_TAG_RQU_COMMAND from the tpm.h
header file in the driver directory to the tpm_input_header declarations
in the driver interface and tpm-sysfs.c.

If a machine reports a RF Button in the communication button device
bitmap, we need to remove it before calling Get Device Status otherwise
it will return the "Undefined device" (0xE2) error code.
Although this may be a BIOS bug, we don't really need to get or set the
RF Button status. The status indicator LED embedded in the button is
controlled by firmware logic, depending on the status of the wireless
radios present on the machine (WiFi || WWAN).
This commit fixes the wireless status indicator LED on the Acer
TravelMate P648-G2-MG, and cleans the following message from the kernel
log: "Get Current Device Status failed: 0xe2 - 0x0".

Notice that the exit code is masked with 255. Thus, be careful if

Now struct spi_master is used for both SPI master and slave controllers,
it makes sense to rename it to struct spi_controller, and replace
"master" by "controller" where appropriate.
For now this conversion is done for SPI core infrastructure only.
Wrappers are provided for backwards compatibility, until all SPI drivers
have been converted.
Noteworthy details:
- SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI
master controllers,
- spi_busnum_to_master() is retained, as it looks up masters only,
- A new field spi_device.controller is added, but spi_device.master is
retained for compatibility (both are always initialized by
spi_alloc_device()),
- spi_flash_read() is used by SPI masters only.

Currently, when looking up a regulator supply, the regulator name
takes priority over the consumer mappings. As there are a lot of
regulator names that are in fairly common use (VDD, MICVDD, etc.) this
can easily lead to obtaining the wrong supply, when a system contains
two regulators that share a name.
The explicit consumer mappings contain much less ambiguity as they
specify both a name and a consumer device. As such prioritise those if
one exists and only fall back to the regulator name if there are no
matching explicit mappings.

The function flush_signals clears all pending signals for the process. It
may be used by kernel threads when we need to prepare a kernel thread for
responding to signals. However using this function for an userspaces
processes is incorrect - clearing signals without the program expecting it
can cause misbehavior.
The raid1 and raid5 code uses flush_signals in its request routine because
it wants to prepare for an interruptible wait. This patch drops
flush_signals and uses sigprocmask instead to block all signals (including
SIGKILL) around the schedule() call. The signals are not lost, but the
schedule() call won't respond to them.

If mddev_suspend() races with md_write_start() we can deadlock
with mddev_suspend() waiting for the request that is currently
in md_write_start() to complete the ->make_request() call,
and md_write_start() waiting for the metadata to be updated
to mark the array as 'dirty'.
As metadata updates done by md_check_recovery() only happen then
the mddev_lock() can be claimed, and as mddev_suspend() is often
called with the lock held, these threads wait indefinitely for each
other.
We fix this by having md_write_start() abort if mddev_suspend()
is happening, and ->make_request() aborts if md_write_start()
aborted.
md_make_request() can detect this abort, decrease the ->active_io
count, and wait for mddev_suspend().
