This prepares 'vsock_connectible_recvmg()' to call SEQPACKET receive
loop:
1) Some shared check left in this function, then socket type
specific receive loop is called.
2) Stream receive loop is moved to separate function.

GCC versions >= 4.9 and < 5.1 have been shown to emit memory references
beyond the stack pointer, resulting in memory corruption if an interrupt
is taken after the stack pointer has been adjusted but before the
reference has been executed.

As we are aiming to be able to control whether we enable VHE or
not, let's always drop down to EL1 first, and only then upgrade
to VHE if at all possible.
This means that if the kernel is booted at EL2, we always start
with a nVHE init, drop to EL1 to initialise the the kernel, and
only then
We can now move the initial SCTLR_EL1 setup to be used for both

With llist_head it is possible to avoid the locking (the irq-off region)
when items are added. This makes it possible to add items on a remote
CPU without additional locking.
llist_add() returns true if the list was previously empty. This can be
used to invoke the SMP function call / raise sofirq

Yes, umm. I accidentally *copied* that line a few lines further down
rather than
Testing need_resched() before cond_resched() is not needed as an
equivalent test is done internally in cond_resched(). So drop the
need_resched() test.

This series adds support for UFS found in SM8350 SoC. First we add UFS HC
compatible strings, along with missing one for SM8250. This can go thru SCSI
subssystem.
Then we add binding for UFS phy and new regsiters and nw offsets specific to
SM8350 followed by UFS phy tables. This can go thru phy
Add the compatible strings for the UFS PHY found on SM8350 SoC.

Add the registers for few new registers found in SM8350. Also the UFS
phy used in SM8350 seems to have different offsets than V4 phy, although
it claims it is v4 phy, so add the new offsets with SM8350 tag instead
of V4 tag.

The FEC drivers performs a "hardware reset" of the MAC module when the
link is reported to be up. This causes a short glitch in the RMII clock
due to the hardware reset clearing the receive control register which
controls the MII mode. It seems that some link

Though do_overwritten() follows do_nothing() in source code, the final
memory address order is determined by compiler. We can't always assume
address of do_overwritten() is bigger than do_nothing(). At least the
Clang we are using places do_overwritten() before do_nothing() in
1001 - 1100 of 1134 matches
