5a3ff8473c ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts
The following commit: 2f31b51659
Author: Tero Kristo <t-kristo@ti.com>
Date:   Fri Dec 16 14:37:00 2011 -0700

    ARM: OMAP4: PRM: use PRCM interrupt handler

introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:

[    0.208221] PRCM: failed to allocate irq descs: -12

Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.

[    1.802795] mux: Failed to setup hwmod io irq -22

Fix that by adding 64 more interrupts for OMAP2PLUS config.

4c90d3b303 tcp: fix false reordering signal in tcp_shifted_skb
When tcp_shifted_skb() shifts bytes from the skb that is currently
pointed to by 'highest_sack' then the increment of
TCP_SKB_CB(skb)->seq implicitly advances tcp_highest_sack_seq(). This
implicit advancement, combined with the recent fix to pass the correct
SACKed range into tcp_sacktag_one(), caused tcp_sacktag_one() to think
that the newly SACKed range was before the tcp_highest_sack_seq(),
leading to a call to tcp_update_reordering() with a degree of
reordering matching the size of the newly SACKed range (typically just
1 packet, which is a NOP, but potentially larger).

This commit fixes this by simply calling tcp_sacktag_one() before the
TCP_SKB_CB(skb)->seq advancement that can advance our notion of the
highest SACKed sequence.

Correspondingly, we can simplify the code a little now that
tcp_shifted_skb() should update the lost_cnt_hint in all cases where
skb == tp->lost_skb_hint.

8411371709 x86/PCI: use host bridge _CRS info on MSI MS-7253
In the spirit of commit 29cf7a30f8 ("x86/PCI: use host bridge _CRS
info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by
default on a board that needs it.

This fixes boot failures and oopses introduced in 3e3da00c01
("x86/pci: AMD one chain system to use pci read out res").  The quirk
is quite targetted (to a specific board and BIOS version) for two
reasons:

 (1) to emphasize that this method of tackling the problem one quirk
     at a time is a little insane

 (2) to give BIOS vendors an opportunity to use simpler tables and
     allow us to return to generic behavior (whatever that happens to
     be) with a later BIOS update

In other words, I am not at all happy with having quirks like this.
But it is even worse for the kernel not to work out of the box on
these machines, so...

d5a74afd08 IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
 biggest one. It fixes the calls of the function omap_find_iovm_area() in
 the omap-iommu-debug module which expects a 'struct device' parameter
 since commit fabdbca instead of an omap_iommu handle. The
 omap-iommu-debug code still passed the handle to the function which
 caused a crash.
 The second patch fixes a NULL pointer dereference in the OMAP code and
 the third patch makes sure that the omap-iommu is initialized before the
 omap-isp driver, which relies on the iommu. The last patch is only a
 workaround until defered probing is implemented.

a365fbf354 GFS2: Read resource groups on mount
This makes mount take slightly longer, but at the same time, the first
write to the filesystem will be faster too. It also means that if there
is a problem in the resource index, then we can refuse to mount rather
than having to try and report that when the first write occurs.

In addition, to avoid recursive locking, we hvae to take account of
instances when the rindex glock may already be held when we are
trying to update the rbtree of resource groups.

9e73f571ea GFS2: Ensure rindex is uptodate for fallocate
This patch fixes a problem whereby gfs2_grow was failing and causing GFS2
to assert. The problem was that when GFS2's fallocate operation tried to
acquire an "allocation" it made sure the rindex was up to date, and if not,
it called gfs2_rindex_update. However, if the file being fallocated was
the rindex itself, it was already locked at that point. By calling
gfs2_rindex_update at an earlier point in time, we bring rindex up to date
and thereby avoid trying to lock it when the "allocation" is acquired.

30ce2f7eef perf/hwbp: Fix a possible memory leak
If kzalloc() for TYPE_DATA failed on a given cpu, previous chunk
of TYPE_INST will be leaked. Fix it.

Thanks to Peter Zijlstra for suggesting this better solution. It
should work as long as the initial value of the region is all
0's and that's the case of static (per-cpu) memory allocation.

586c6e7013 While demoing ktest at ELC in 2012, it was embarrassing that the
make_min_config test failed to work because the snowball board I was tesing
 it against had a config that would not build. But the make_min_config
 only tested the testing part and ignored build failures. The end result
 was a config file that would not boot.
 
 This time, for real.

bf1c95abaf ktest: Fix make_min_config test when build fails
The make_min_config does not take into account when the build fails,
resulting in a invalid MIN_CONFIG .config file. When the build fails,
it is ignored and the boot test is executed, using the previous built
kernel. The configs that should be tested are not tested and they may
be added or removed depending on the result of the last kernel that
succeeded to be built.

If the build fails, mark the current config as a failure and the
configs that were disabled may still be needed.

5d031e5b63 drm/i915: Remove use of the autoreported ringbuffer HEAD position
This is a revert of 6aa56062ea.

This was originally introduced to workaround reads of the ringbuffer
registers returning 0 on SandyBridge causing hangs due to ringbuffer
overflow. The root cause here was reads through the GT powerwell require
the forcewake dance, something we only learnt of later. Now it appears
that reading the reported head position from the HWS is returning
garbage, leading once again to hangs.

For example, on q35 the autoreported head reports:
  [  217.975608] head now 00010000, actual 00010000
  [  436.725613] head now 00200000, actual 00200000
  [  462.956033] head now 00210000, actual 00210010
  [  485.501409] head now 00400000, actual 00400020
  [  508.064280] head now 00410000, actual 00410000
  [  530.576078] head now 00600000, actual 00600020
  [  553.273489] head now 00610000, actual 00610018
which appears reasonably sane. In contrast, if we look at snb:
  [  141.970680] head now 00e10000, actual 00008238
  [  141.974062] head now 02734000, actual 000083c8
  [  141.974425] head now 00e10000, actual 00008488
  [  141.980374] head now 032b5000, actual 000088b8
  [  141.980885] head now 03271000, actual 00008950
  [  142.040628] head now 02101000, actual 00008b40
  [  142.180173] head now 02734000, actual 00009050
  [  142.181090] head now 00000000, actual 00000ae0
  [  142.183737] head now 02734000, actual 00009050

In addition, the automatic reporting of the head position is scheduled
to be defeatured in the future. It has no more utility, remove it.
