51af243c63 [ARM] MINI2440: Add missing flash_bbt flat to NAND
The commit 9db41f9edc added
the .flash_bbt flag to the nand set, so add this back into
the mach-mini2440.c file (taken out on initial commit to
allow build).

That's HAVE_PERF_COUNTERS not HAVE_PERF_COUNTER. This was right
initially but I seem to have screwed it up while re-typing it out

b647712f66 [ARM] S3C: Fix S3C24XX build to not include s3c64xx IIS devices
Commit 52da219e96 added IIS
platform devices, but these do not build on s3c24xx systems
and the file depends on SND_S3C24XX_SOC, which is selected
for all S3C64XX/S3C24XX systems.

As a quick fix, make the dev-audio.o file depends on
SND_S3C64XX_SOC_I2S instead.

e4d24ec39c OMAP1: Fix N770 MMC support
Some of the N770's MMC configuration options seem to have been
dropped. This patch adds them back in again.

Note that only the .ocr_mask change was /critical/, but I've added the
.max_freq setting back as well, as the original sources had it. Can
anyone confirm if this is unnecessary?

Secondly, there is support in the original code for a 4wire/higher
speed mode. As I don't have the requisite N770 hardware (I think it
was a rev2 N770?) to test this, I can't really add it back.

optimize the inherit path in the next patch.

Remove the child_counter->atrr.inherit = 1 line because the
only way to get there is if parent_counter->attr.inherit == 1
and we copy the attrs.

f29ac756a4 perf_counter: Optimize perf_swcounter_event()
Similar to tracepoints, use an enable variable to reduce
overhead when unused.

Only look for a counter of a particular event type when we know
there is at least one in the system.

3d906ef10a perf_counter tools: Handle overlapping MMAP events
Martin Schwidefsky reported "perf report" symbol resolution
problems on S390.

Since we only report MMAP, not MUNMAP, we have to deal with
overlapping maps.

We used to simply throw out the old map on the assumption whole
maps got unmapped. This obviously doesn't deal with partial
unmaps. However it appears some dynamic linkers do fancy
partial unmaps (s390), so do something more elaborate and
truncate the old maps, only removing them when they've been
fully covered.

This resolves (part of) the S390 symbol resolution problems.

bfdb4d9f0f timers: Fix timer_migration interface which accepts any number as input
Poornima Nayek reported:

| Timer migration interface /proc/sys/kernel/timer_migration in
| 2.6.30-git9 accepts any numerical value as input.
|
| Steps to reproduce:
| 1. echo -6666666 > /proc/sys/kernel/timer_migration
| 2. cat /proc/sys/kernel/timer_migration
| -6666666
|
| 1. echo 44444444444444444444444444444444444444444444444444444444444 > /proc/sys/kernel/timer_migration
| 2. cat /proc/sys/kernel/timer_migration
| -1357789412
|
| Expected behavior: Should 'echo: write error: Invalid argument' while
| setting any value other then 0 & 1

Restrict valid values to 0 and 1.

971121f271 sh: Fix up more dma-mapping fallout.
commit dbe6f18691
("dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated"
conveniently broke every single SH build.

In the future it would be great if people could at least bother
figuring out how to use grep.

854c879f5a x86: Move init_gbpages() to setup_arch()
The init_gbpages() function is conditionally called from
init_memory_mapping() function. There are two call-sites where
this 'after_bootmem' condition can be true: setup_arch() and
mem_init() via pci_iommu_alloc().

Therefore, it's safe to move the call to init_gbpages() to
setup_arch() as it's always called before mem_init().

This removes an after_bootmem use - paving the way to remove
all uses of that state variable.

2eb2a43682 sh: SH7786 SMP support.
SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.
