Somehow this select statement managed to squeeze itself between commit
0e152d80507b75c00aac60f2ffc586360687cd52 ("m68k: reorganize Kconfig

95e82747d6e2abc513bfae416e6009968985d05b ("m68k: drop unused Kconfig

The select statement for that symbol is a nop. Drop it.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net into intel
Jeff Kirsher says:
===================
This series contains fixes to e1000e and igb.
The e1000e fix resolves an issue at 1000Mbps link speed, where one of the
MAC's internal clocks can be stopped for up to 4us when entering K1 (a
power mode of the MAC-PHY interconnect). If the MAC is waiting for
completion indications for 2 DMA write requests into Host memory
(e.g. descriptor writeback or Rx packet writing) and the
indications occur while the clock is stopped, both indications will be
missed by the MAC causing the MAC to wait for the completion indications
and be unable to generate further DMA write requests. This results in an
apparent hardware hang. The patch works-around the issue by disabling
the de-assertion of the clock request when 1000Mbps link is acquired (K1
must be disabled while doing this).
The igb fix to drop BUILD_BUG_ON check from igb_build_rx_buffer resolves
a build error on s390 devices. The igb driver was throwing a build error
due to the fact that a frame built using build_skb would be larger than 2K.
Since this is not likely to change at any point in the future we are better
off just dropping the check since we already had a check in
igb_set_rx_buffer_len that will just disable the usage of build_skb anyway.
The igb fix for i210 link setup changes the setup copper link function
to use a switch statement, so that the appropriate setup link function
is called for the given PHY types.
Lastly, the igb fix for a lockdep issue in igb_get_i2c_client resolves
the issue by re-factoring the initialization and usage of the i2c_client.

From the docs:
"IIR can queue up to two interrupt events. When the IIR is cleared,
it will set itself again after one clock if a second event was
stored."
"Only the rising edge of the PCH Display interrupt will cause the
North Display IIR (DEIIR) PCH Display Interrupt even bit to be set,
so all PCH Display Interrupts, including back to back interrupts,
must be cleared before a new PCH Display interrupt can cause DEIIR
to be set".
The current code works fine because we don't get many interrupts, but
if we enable the PCH FIFO underrun interrupts we'll start getting so
many interrupts that at some point new PCH interrupts won't cause
DEIIR to be set.
The initial implementation I tried was to turn the code that checks
SDEIIR into a loop, but we can still get interrupts even after the
loop is done (and before the irq handler finishes), so we have to
either disable the interrupts or mask them. In the end I concluded
that just disabling the PCH interrupts is enough, you don't even need
the loop, so this is what this patch implements. I've tested it and it
passes the 2 "PCH FIFO underrun interrupt storms" I can reproduce:
the "ironlake_crtc_disable" case and the "wrong watermarks" case.
In other words, here's how to reproduce the problem fixed by this
patch:
1 - Enable PCH FIFO underrun interrupts (SERR_INT on SNB+)
2 - Boot the machine
3 - While booting we'll get tons of PCH FIFO underrun interrupts
4 - Plug a new monitor
5 - Run xrandr, notice it won't detect the new monitor
6 - Read SDEIIR and notice it's not 0 while DEIIR is 0
Q: Can't we just clear DEIIR before SDEIIR?
A: It doesn't work. SDEIIR has to be completely cleared (including the
interrupts stored on its back queue) before it can flip DEIIR's bit to
1 again, and even while you're clearing it you'll be getting more and
more interrupts.
Q: Why does it work by just disabling+enabling the south interrupts?
A: Because when we re-enable them, if there's something on the SDEIIR
register (maybe an interrupt stored on the queue), the re-enabling
will make DEIIR's bit flip to 1, and since we'll already have
interrupts enabled we'll get another interrupt, then run our irq
handler again to process the "back" interrupts.
v2: Even bigger commit message, added code comments.

3.9-rc1. This regression has been introduced by switching to

Commit 24542bf7ea5e4fdfdb5157ff544c093fa4dcb536 changed preallocation of
extents to cap the max size we try to allocate. It's a valid change,
but the extent reservation code is also used by balance, and that
can't tolerate a smaller extent being allocated.
__btrfs_prealloc_file_range already has a min_size parameter, which is
used by relocation to request a specific extent size. This commit
adds an extra check to enforce that minimum extent size.

When a value of a vmaster slave control is changed, the ctl change
notification is sometimes ignored. This happens when the master
control overrides, e.g. when the corresponding master control is
muted. The reason is that slave_put() returns the value of the actual
slave put callback, and it doesn't reflect the virtual slave value
change.
This patch fixes the function just to return 1 whenever a slave value
is changed.

Commit 80ab72e1 (usb: musb: omap2430: fix the readiness check
in omap_musb_mailbox) made the check incorrect, as we will lose the
glue/link status during the normal built-in probe order (twl4030_usb is
probed after musb omap2430, but before musb core is ready).
As a result, if you boot with USB cable on and load g_ether, the
connection does not work as the code thinks the cable is off and the
phy gets powered down immediately. This is a major regression in 3.9-rc1.
So the proper check should be: exit if _glue is NULL, but if it's
initialized we memorize the status, and then check if the musb core
is ready.

Currently we use the link register to branch up high in the early MMU on
syscall entry path. Unfortunately, this trashes the link stack as the
address we are going to is not associated with the earlier mflr.
This patch simply converts us to used the count register (volatile over
syscalls anyway) instead. This is much better at predicting in this
scenario and doesn't trash link stack causing a bunch of additional
branch mispredicts later. Benchmarking this on POWER8 saves a bunch of
cycles on Anton's null syscall benchmark here:

when strlen pi->location_code is larger than HVCS_CLC_LENGTH + 1,
original implementation can not let hvcsd->p_location_code NUL terminated.
so need fix it (also can simplify the code)

the dest buf len is 80 (HVCS_CLC_LENGTH + 1).
the src buf len is PAGE_SIZE.
if src buf string len is more than 80, it will cause issue.

This register field is 11 bits wide, not 15 bits wide. Given the way
this value is currently, used, this patch has no practical effect.
However, it's still best if the value is correct.

This fixes the following error while booting the kernel:
smp_twd: clock not found -2
