wl12xx_sdio_power_off() manually powers down the card regardless of the
runtime pm state. If wl12xx_sdio_power_on() is called before the card
was suspended by runtime PM, it will not power up the card.
As part of the HW detection, the chip's power is toggled. Since this
happens in the context of probing sdio, the power reference counter will
be higher than zero. As a result, when wl12xx_sdio_power_off() is
called, the chip will be powered down while still having a positive
power reference counter. If the interface is quickly activated, the
driver might try to transfer data to a powered off chip.
Fix this by ensuring that wl12xx_sdio_power_on() explicitly powers on
the chip in case runtime pm claims the chip is already powered on. To
avoid cases in which it is not possible to determine if the chip was
really powered on (card's power reference counter is positive), operate
on the mmc_card instead of the function.
Also verify that the chip is indeed powered on before powering off, to
avoid wrong reference counter values in error cases.

Commit de1cbee which removed b_file_offset in favor of b_bn introduced a bug
causing xfs_buf_allocate_memory() to overestimate the number of necessary
pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively
every buffer is straddling a page boundary which causes
xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access
which is unnecessary.
Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the
buffer is inserted into the cache only after being fully initialized now.
So just make xfs_buf_alloc() fill in proper block number from the beginning.

An inode in the AIL can be flush locked and marked stale if
a cluster free transaction occurs at the right time. The
inode item is then marked as flushing, which causes xfsaild

reproduced by running xfstests 273 in a loop for an

Check for stale inodes before the flush lock. This marks

FW uses a few memory blocks as a buffer to accumulate FW logs before
transmitting them to the host over SDIO. When FW WatchDog recovery
occurs, the last FW traces are still pending in the buffer. Driver is
to read these FW traces whether log mode is continuous or on demand.
FW memory blocks allocated for the log buffer are handled as a link list:
the first 4 bytes in each memory block contain FW address to the next block.
The end of list condition depends on FW log mode:
- on demand: the list is cyclic, the next address is equal to the first address
- continuous: the address is equal to 0x2000000
Log data resides inside FW memory block with offset depending on
logger mode:
- on demand: 4 bytes (address of the next memory block)
- continuous: 4 bytes and Rx Descriptor structure size
Described FW logger API is backward compatible with previous FW versions.
