Commit a7a20d1039 ("sd: limit the scope of the async probe domain")
make the SCSI device probing run device discovery in it's own async
domain.
However, as a result, the partition detection was no longer synchronized
by async_synchronize_full() (which, despite the name, only synchronizes
the global async space, not all of them). Which in turn meant that
"wait_for_device_probe()" would not wait for the SCSI partitions to be
parsed.
And "wait_for_device_probe()" was what the boot time init code relied on
for mounting the root filesystem.
Now, most people never noticed this, because not only is it
timing-dependent, but modern distributions all use initrd. So the root
filesystem isn't actually on a disk at all. And then before they
actually mount the final disk filesystem, they will have loaded the
scsi-wait-scan module, which not only does the expected
wait_for_device_probe(), but also does scsi_complete_async_scans().
[ Side note: scsi_complete_async_scans() had also been partially broken,
but that was fixed in commit 43a8d39d01 ("fix async probe
regression"), so that same commit a7a20d1039 had actually broken
setups even if you used scsi-wait-scan explicitly ]
Solve this problem by just moving the scsi_complete_async_scans() call
into wait_for_device_probe(). Everybody who wants to wait for device
probing to finish really wants the SCSI probing to complete, so there's
no reason not to do this.
So now "wait_for_device_probe()" really does what the name implies, and
properly waits for device probing to finish. This also removes the now
unnecessary extra calls to scsi_complete_async_scans().

sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl
register bit no. 23:25, with following possibilities
0XX: pll1_clk
10X: sys_synth_clk
110: pll2_clk
111: pll3_clk
Out of several possibilities (h/w wise) to select same clock parent for
sys_clk, current clock implementation was considering just one value.
When bootloader programmed different (valid) value to select a clock
parent then Linux breaks.
Here, we try to include all possibilities which can lead to same
clock selection thus making Linux independent of bootloader selection
values.

The commit 4197aa7bb8 implements 64 bit
per ring statistics. But the driver resets the 'total_bytes' and
'total_packets' from RX and TX rings in the RX and TX interrupt

issue by preventing the resetting of RX and TX ring statistics to

However, dev->transport->get_blocks(dev) (perhaps confusingly) returns

This patch fixes a crash seen when large reads have their exchange
aborted by either timing out or being reset. Because the exchange
abort results in the seq pointer being set to NULL, because the
sequence is no longer valid, it must not be dereferenced. This
patch changes the function ft_get_task_tag to return ~0 if it is
unable to get the tag for this reason. Because the get_task_tag
interface provides no means of returning an error, this seems
like the best way to fix this issue at the moment.

The original pin registers table is derived from u-boot mainline,
but somehow it was found missing some mux functions for USBOTG_ID.
We added it at the bottom by following the exist pin function ids,
then it will not break the exist using of pin function id in dts file.

Occasionally, the PHY can be initially inaccessible when the first read of
a PHY register, e.g. PHY_ID1, happens (signified by the returned value
0xFFFF) but subsequent accesses of the PHY work as expected. Add a retry
counter similar to how it is done in the generic e1000_get_phy_id().
Also, when the PHY is completely inaccessible (i.e. when subsequent reads
of the PHY_IDx registers returns all F's) and the MDIO access mode must be
set to slow before attempting to read the PHY ID again, the functions that
do these latter two actions expect the SW/FW/HW semaphore is not already
set so the semaphore must be released before and re-acquired after calling
them otherwise there is an unnecessarily inordinate amount of delay during
device initialization.

SYNCH bit and IV bit of RXCW register are sticky. Before examining these bits,
RXCW should be read twice to filter out one-time false events and have correct
values for these bits. Incorrect values of these bits in link check logic can
cause weird link stability issues if auto-negotiation fails.

Commit d640113fe8 introduced a regression on SMP
systems where the processor core with ACPI id zero is disabled
(typically should be the case because of hyperthreading).
The regression got spread through stable kernels.
On 3.0.X it got introduced via 3.0.18.
Such platforms may be rare, but do exist.
Look out for a disabled processor with acpi_id 0 in dmesg:
ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled)
This problem has been observed on a:
HP Proliant BL280c G6 blade
This patch restricts the introduced workaround to platforms
with nr_cpu_ids <= 1.
