Change slow_clock()/at91_slow_clock() prototype to accept the PMC
base address and one or two RAM controller addresses by parameters.
The r0, r1 and r2 registers are used differently and preserved during
function call.
Those values are defined in pm.c and slow_clock() function is called
from there with its new parameters.
This will allow to have a soc independent pm_slowclock.

One patch fixes an bug in the ARM/MSM IOMMU code which returned sucess
in the unmap function even when an error occured and the other patch

the table but actually translated by the iommu).

SPI bug fixes for v3.3-rc2
Minor SPI device driver changes. A rename of the pch_spi_pcidev symbol
that merely eliminates a modpost warning, and a Kconfig change to allow
the Samsung spi driver to build on EXYNOS.
* tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6:
spi-topcliff-pch: rename pch_spi_pcidev to pch_spi_pcidev_driver
spi: Add spi-s3c64xx driver dependency on ARCH_EXYNOS4
Five fixes
* branch 'akpm':
pcmcia: fix socket refcount decrementing on each resume
mm: fix UP THP spin_is_locked BUGs
drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmax
mm: compaction: check for overlapping nodes during isolation for migration
nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments()
This fixes a memory-corrupting bug: not only does it cause the warning,
but as a result of dropping the refcount to zero, it causes the
pcmcia_socket0 device structure to be freed while it still has
references, causing slab caches corruption. A fatal oops quickly
follows this warning - often even just a 'dmesg' following the warning
causes the kernel to oops.
While testing suspend/resume on an ARM device with PCMCIA support, and a
CF card inserted, I found that after five suspend and resumes, the
kernel would complain, and shortly die after with slab corruption.

Looking at commit 7b24e79882 ("pcmcia: split up central event handler"),
the following change was made to cs.c:
return 0;
}
#endif
-
- send_event(skt, CS_EVENT_PM_RESUME, CS_EVENT_PRI_LOW);
+ if (!(skt->state & SOCKET_CARDBUS) && (skt->callback))
+ skt->callback->early_resume(skt);
return 0;
}
And the corresponding change in ds.c is from:
-static int ds_event(struct pcmcia_socket *skt, event_t event, int priority)
-{
- struct pcmcia_socket *s = pcmcia_get_socket(skt);
...
- switch (event) {
...
- case CS_EVENT_PM_RESUME:
- if (verify_cis_cache(skt) != 0) {
- dev_dbg(&skt->dev, "cis mismatch - different card\n");
- /* first, remove the card */
- ds_event(skt, CS_EVENT_CARD_REMOVAL, CS_EVENT_PRI_HIGH);
- mutex_lock(&s->ops_mutex);
- destroy_cis_cache(skt);
- kfree(skt->fake_cis);
- skt->fake_cis = NULL;
- s->functions = 0;
- mutex_unlock(&s->ops_mutex);
- /* now, add the new card */
- ds_event(skt, CS_EVENT_CARD_INSERTION,
- CS_EVENT_PRI_LOW);
- }
- break;
...
- }
- pcmcia_put_socket(s);
- return 0;
-} /* ds_event */
to:
+static int pcmcia_bus_early_resume(struct pcmcia_socket *skt)
+{
+ if (!verify_cis_cache(skt)) {
+ pcmcia_put_socket(skt);
+ return 0;
+ }
+ dev_dbg(&skt->dev, "cis mismatch - different card\n");
+ /* first, remove the card */
+ pcmcia_bus_remove(skt);
+ mutex_lock(&skt->ops_mutex);
+ destroy_cis_cache(skt);
+ kfree(skt->fake_cis);
+ skt->fake_cis = NULL;
+ skt->functions = 0;
+ mutex_unlock(&skt->ops_mutex);
+ /* now, add the new card */
+ pcmcia_bus_add(skt);
+ return 0;
+}
As can be seen, the original function called pcmcia_get_socket() and
pcmcia_put_socket() around the guts, whereas the replacement code
calls pcmcia_put_socket() only in one path. This creates an imbalance
in the refcounting.
Testing with pcmcia_put_socket() put removed shows that the bug is gone:

In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and
pltfm->als_vmax is 0. This does not make sense. I think what we want
here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV.
Both als_vmin and als_vmax local variables will be set to
pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also
remove a redundant assignment for als_vmin and als_vmax in this patch.

When isolating pages for migration, migration starts at the start of a
zone while the free scanner starts at the end of the zone. Migration
avoids entering a new zone by never going beyond the free scanned.
Unfortunately, in very rare cases nodes can overlap. When this happens,
migration isolates pages without the LRU lock held, corrupting lists
which will trigger errors in reclaim or during page free such as in the
following oops

The "X" in the taint flag means that external modules were loaded but but
is unrelated to the bug triggering. The real problem was because the PFN
layout looks like this
Zone PFN ranges:
DMA 0x00000010 -> 0x00001000
DMA32 0x00001000 -> 0x00100000
Normal 0x00100000 -> 0x01e80000
Movable zone start PFN for each node
early_node_map[14] active PFN ranges
0: 0x00000010 -> 0x0000009b
0: 0x00000100 -> 0x0007a1ec
0: 0x0007a354 -> 0x0007a379
0: 0x0007f7ff -> 0x0007f800
0: 0x00100000 -> 0x00680000
1: 0x00680000 -> 0x00e80000
0: 0x00e80000 -> 0x01080000
1: 0x01080000 -> 0x01280000
0: 0x01280000 -> 0x01480000
1: 0x01480000 -> 0x01680000
0: 0x01680000 -> 0x01880000
1: 0x01880000 -> 0x01a80000
0: 0x01a80000 -> 0x01c80000
1: 0x01c80000 -> 0x01e80000
The fix is straight-forward. isolate_migratepages() has to make a
similar check to isolate_freepage to ensure that it never isolates pages
from a zone it does not hold the LRU lock for.
This was discovered in a 3.0-based kernel but it affects 3.1.x, 3.2.x
and current mainline.

The driver accidentally exchanged the left/right fields for stereo AC'97
mixer registers. This affected only the aux and CD inputs because the
line input bypasses the AC'97 codec and the mic input is mono; cards
without AC'97 (Xonar DS/DG/HDAV Slim, HG2PCI, HiFier) were not affected.

Merge tag 'asoc-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
The only particularly remarkable change here is the one for handling of
the Android suspend ignore code for idle_bias_off CODECs. That one is
actually a regression fix as some of the new power savings that have
been introduced confused the suspend ignore code, making devices that
are active for non-audio reasons look like they are idle causing them to
be suspended instead of being kept active.
This patch fixes a bug in target-core where unsupported WRITE_SAME ops
from a target_check_write_same_discard() failure was incorrectly
returning CHECK_CONDITION w/ TCM_INVALID_CDB_FIELD sense data.
This was causing some clients to not properly fall back, so go ahead
and use the correct TCM_UNSUPPORTED_SCSI_OPCODE sense for this case.

Use IP_FREEBIND socket option so that iscsi portal configuration with
explicit IP addresses can happen during boot, before network interfaces
have been assigned IPs.
This is especially important on systemd based Linux boxes where system
boot happens asynchronously and non-trivial configuration must be done
to get targetcli.service to start synchronously after the network is
configured.
