arm64: Tell irq work about self IPI support

2014-10-15T10:29:25+00:00

commit 3631073659d0aafeaa52227bb61a100efaf901dc upstream.

ARM64 irq work self-IPI support depends on __smp_cross_call to point to
some relevant IRQ controller operations. This information should be
available after the call to init_IRQ().

Lets implement arch_irq_work_has_interrupt() accordingly.

libata: Un-break ATA blacklist

2014-10-15T10:29:25+00:00

commit 1c40279960bcd7d52dbdf1d466b20d24b99176c8 upstream.

lib/glob.c provides a new glob_match() function, with arguments in
(pattern, string) order.  It replaced a private function with arguments
in (string, pattern) order, but I didn't swap the call site...

The result was the entire ATA blacklist was effectively disabled.

The lesson for today is "I f***ed up *how* badly *how* many months ago?",
er, I mean "Nobody Tests RC Kernels On Legacy Hardware".

This was not a subtle break, but it made it through an entire RC
cycle unreported, presumably because all the people doing testing
have full-featured hardware.

(FWIW, the reason for the argument swap was because fnmatch() does it that
way, and for a while implementing a full fnmatch() was being considered.)

serial: 8250: Add Quark X1000 to 8250_pci.c

2014-10-15T10:29:24+00:00

commit 1ede7dcca3c4fa15a518ab0473126f9c3e621e4c upstream.

Quark X1000 contains two designware derived 8250 serial ports.
Each port has a unique PCI configuration space consisting of
BAR0:UART BAR1:DMA respectively.

Unlike the standard 8250 the register width is 32 bits for RHR,IER etc
The Quark UART has a fundamental clock @ 44.2368 MHz allowing for a
bitrate of up to about 2.76 megabits per second.

This patch enables standard 8250 mode

driver/base/node: remove unnecessary kfree of node struct from unregister_one_node

2014-10-15T10:29:24+00:00

commit 33ead538f642a33b1d658782a5d14a40b5014d1f upstream.

Commit 92d585ef067d ("numa: fix NULL pointer access and memory
leak in unregister_one_node()") added kfree() of node struct in
unregister_one_node(). But node struct is freed by node_device_release()
which is called in  unregister_node(). So by adding the kfree(),
node struct is freed two times.

While hot removing memory, the commit leads the following BUG_ON():

crypto: caam - fix addressing of struct member

2014-10-15T10:29:24+00:00

commit 4451d494b1910bf7b7f8381a637d0fe6d2142467 upstream.

buf_0 and buf_1 in caam_hash_state are not next to each other.
Accessing buf_1 is incorrect from &buf_0 with an offset of only
size_of(buf_0). The same issue is also with buflen_0 and buflen_1

USB: Add device quirk for ASUS T100 Base Station keyboard

2014-10-15T10:29:24+00:00

commit ddbe1fca0bcb87ca8c199ea873a456ca8a948567 upstream.

This full-speed USB device generates spurious remote wakeup event
as soon as USB_DEVICE_REMOTE_WAKEUP feature is set. As the result,
Linux can't enter system suspend and S0ix power saving modes once
this keyboard is used.

This patch tries to introduce USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk.
With this quirk set, wakeup capability will be ignored during
device configure.

This patch could be back-ported to kernels as old as 2.6.39.

usb: musb: dsps: kill OTG timer on suspend

2014-10-15T10:29:24+00:00

commit 468bcc2a2ca071f652009d2d20d97f2437630cae upstream.

if we don't make sure to kill the timer, it could
expire after we have already gated our clocks.

That will trigger a Data Abort exception because
we would try to access register while clock is gated.

Fix that bug.
