iMX51: introduce IMX_GPIO_NR
Currently, to define a GPIO number, we're using something like :
#define EFIKAMX_PCBID0 (2*32 + 16)
to define GPIO 3 16.
This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :
#define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16)
v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR

This reverts commit
e0fdace10e75dac67d906213b780ff1b1a4cc360.
On-list discussion seems to suggest that the robustness fixes for printk
make this unnecessary and DaveM has also agreed in person at Kernel Summit
and on list.
The main problem with this code is once we hit a lockdep splat we always
keep oops_in_progress set, the console layer uses oops_in_progress with KMS
to decide when it should be showing the oops and not showing X, so it causes
problems around suspend/resume time when a userspace resume can cause a console
switch away from X, only if oops_in_progress is set (which is what we want
if an oops actually is in progress, but not because we had a lockdep splat
2 days prior).

tpm: Autodetect itpm devices
Some Lenovos have TPMs that require a quirk to function correctly. This can
be autodetected by checking whether the device has a _HID of INTC0102. This
is an invalid PNPid, and as such is discarded by the pnp layer - however
it's still present in the ACPI code, so we can pull it out that way. This
means that the quirk won't be automatically applied on non-ACPI systems,
but without ACPI we don't have any way to identify the chip anyway so I
don't think that's a great concern.

af_unix: limit recursion level
Its easy to eat all kernel memory and trigger NMI watchdog, using an
exploit program that queues unix sockets on top of others.
lkml ref : http://lkml.org/lkml/2010/11/25/8
This mechanism is used in applications, one choice we have is to have a
recursion limit.
Other limits might be needed as well (if we queue other types of files),
since the passfd mechanism is currently limited by socket receive queue
sizes only.
Add a recursion_level to unix socket, allowing up to 4 levels.
Each time we send an unix socket through sendfd mechanism, we copy its
recursion level (plus one) to receiver. This recursion level is cleared
when socket receive queue is emptied.

inet sockets corresponding to passive connections are added to the bind hash

__inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas
___inet_inherit_port() does not increment them. This results in both of these
going to -ve values.

tcp: restrict net.ipv4.tcp_adv_win_scale (#20312)
tcp_win_from_space() does the following:
if (sysctl_tcp_adv_win_scale <= 0)
return space >> (-sysctl_tcp_adv_win_scale);
else
return space - (space >> sysctl_tcp_adv_win_scale);
"space" is int.
As per C99 6.5.7 (3) shifting int for 32 or more bits is
undefined behaviour.
Indeed, if sysctl_tcp_adv_win_scale is exactly 32,
space >> 32 equals space and function returns 0.
Which means we busyloop in tcp_fixup_rcvbuf().
Restrict net.ipv4.tcp_adv_win_scale to [-31, 31].
Fix https://bugzilla.kernel.org/show_bug.cgi?id=20312
Steps to reproduce:

Btrfs: setup blank root and fs_info for mount time
There is a problem with how we use sget, it searches through the list of supers
attached to the fs_type looking for a super with the same fs_devices as what
we're trying to mount. This depends on sb->s_fs_info being filled, but we don't
fill that in until we get to btrfs_fill_super, so we could hit supers on the
fs_type super list that have a null s_fs_info. In order to fix that we need to
go ahead and setup a blank root with a blank fs_info to hold fs_devices, that
way our test will work out right and then we can set s_fs_info in
btrfs_set_super, and then open_ctree will simply use our pre-allocated root and
fs_info when setting everything up. Thanks,

Btrfs: fix fiemap
There are two big problems currently with FIEMAP
1) We return extents for holes. This isn't supposed to happen, we just don't
return extents for holes and then userspace interprets the lack of an extent as
a hole.
2) We sometimes don't set FIEMAP_EXTENT_LAST properly. This is because we wait
to see a EXTENT_FLAG_VACANCY flag on the em, but this won't happen if say we ask
fiemap to map up to the last extent in a file, and there is nothing but holes up
to the i_size. To fix this we need to lookup the last extent in this file and
save the logical offset, so if we happen to try and map that extent we can be
sure to set FIEMAP_EXTENT_LAST.
With this patch we now pass xfstest 225, which we never have before.

ALSA: hda - Use ALC_INIT_DEFAULT for really default initialization
When SKU assid gives no valid bits for 0x38, the driver didn't take
any action, so far. This resulted in the missing initialization for
external amps, etc, thus the silent output in the end.
Especially users hit this problem on ALC888 newly since 2.6.35,
where the driver doesn't force to use ALC_INIT_DEFAULT any more.
This patch sets the default initialization scheme to use
ALC_INIT_DEFAULT when no valid bits are set for SKU assid.

x86, perf, nmi: Disable perf if counters are not accessible
In a kvm virt guests, the perf counters are not emulated. Instead they
return zero on a rdmsrl. The perf nmi handler uses the fact that crossing
a zero means the counter overflowed (for those counters that do not have
specific interrupt bits). Therefore on kvm guests, perf will swallow all
NMIs thinking the counters overflowed.
This causes problems for subsystems like kgdb which needs NMIs to do its
magic. This problem was discovered by running kgdb tests.
The solution is to write garbage into a perf counter during the
initialization and hopefully reading back the same number. On kvm
guests, the value will be read back as zero and we disable perf as
a result.

[S390] nmi: fix clock comparator revalidation
On each machine check all registers are revalidated. The save area for
the clock comparator however only contains the upper most seven bytes
of the former contents, if valid.
Therefore the machine check handler uses a store clock instruction to
get the current time and writes that to the clock comparator register
which in turn will generate an immediate timer interrupt.
However within the lowcore the expected time of the next timer
interrupt is stored. If the interrupt happens before that time the
handler won't be called. In turn the clock comparator won't be
reprogrammed and therefore the interrupt condition stays pending which
causes an interrupt loop until the expected time is reached.
On NOHZ machines this can result in unresponsive machines since the
time of the next expected interrupted can be a couple of days in the
future.
To fix this just revalidate the clock comparator register with the
expected value.
In addition the special handling for udelay must be changed as well.

OMAP2+: PM/serial: hold console semaphore while OMAP UARTs are disabled
The console semaphore must be held while the OMAP UART devices are
disabled, lest a console write cause an ARM abort (and a kernel crash)
when the underlying console device is inaccessible. These crashes
only occur when the console is on one of the OMAP internal serial
ports.
While this problem has been latent in the PM idle loop for some time,
the crash was not triggerable with an unmodified kernel until commit
6f251e9db1093c187addc309b5f2f7fe3efd2995 ("OMAP: UART: omap_device
conversions, remove implicit 8520 assumptions"). After this patch, a
console write often occurs after the console UART has been disabled in
the idle loop, crashing the system. Several users have encountered
this bug:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg38396.html
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36602.html
The same commit also introduced new code that disabled the UARTs
during init, in omap_serial_init_port(). The kernel will also crash
in this code when earlyconsole and extra debugging is enabled:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36411.html
The minimal fix for the -rc series is to hold the console semaphore
while the OMAP UARTs are disabled. This is a somewhat overbroad fix,
since the console may not be located on an OMAP UART, as is the case
with the GPMC UART on Zoom3. While it is technically possible to
determine which devices the console or earlyconsole is actually
running on, it is not a trivial problem to solve, and the code to do
so is not really appropriate for the -rc series.
The right long-term fix is to ensure that no code outside of the OMAP
serial driver can disable an OMAP UART. As I understand it, code to
implement this is under development by TI.
