2b768b6cdb [ARM] 5391/1: AT91: Enable GPIO clocks earlier
Enable the GPIO clocks earlier in the initialization sequence.  This
allow the board-setup code to read and set GPIO pins.

2af29b7861 [ARM] 5390/1: AT91: Watchdog fixes
The recently merged AT91SAM9 watchdog driver uses the
AT91SAM9X_WATCHDOG config variable, whereas the original version of
the driver (and the platform support code) used AT91SAM9_WATCHDOG.
This causes the watchdog platform_device to never be registered, and
therefore the driver not to be initialized.

This patch:
- updates the platform support code to use AT91SAM9X_WATCHDOG.
- includes <linux/io.h> to fix compile error (same fix as was applied
to at91rm9200_wdt.c)
- fixes comment regarding watchdog clock-rates in at91rm9200.

2acf2c261b ext4: Implement range_cyclic in ext4_da_writepages instead of write_cache_pages
With delayed allocation we lock the page in write_cache_pages() and
try to build an in memory extent of contiguous blocks.  This is needed
so that we can get large contiguous blocks request.  If range_cyclic
mode is enabled, write_cache_pages() will loop back to the 0 index if
no I/O has been done yet, and try to start writing from the beginning
of the range.  That causes an attempt to take the page lock of lower
index page while holding the page lock of higher index page, which can
cause a dead lock with another writeback thread.

The solution is to implement the range_cyclic behavior in
ext4_da_writepages() instead.

For those in the init namespace, while we're waiting to remove
the sysfs entry for the uid the uid is still hashed, and
alloc_uid() may re-grab that uid without getting a new
reference to the user_ns, which we've already put in free_user
before scheduling remove_user_sysfs_dir().

When used with the generic AC97 codec support that will provide the

just issue such requests normally.

3997ad317f timers: more consistently use clock vs timer
While reviewing the manpages, I noticed I'd missed some clock vs timer sites.

Make sure that all timer functions call cpu_timer_sample_group() and not
cpu_clock_sample_group(). This ensures that we enable the process wide timer
in time, and therefore pay the O(n) thread group cost from the syscall.

Not doing it here, will result in the first jiffy tick after setting the timer
doing this, resulting in a very expensive tick (but only once) and a delay in
actually starting the timer.

b13e24644c x86, hpet: fix for LS21 + HPET = boot hang
Between 2.6.23 and 2.6.24-rc1 a change was made that broke IBM LS21
systems that had the HPET enabled in the BIOS, resulting in boot hangs
for x86_64.

Specifically commit b8ce335906, which
merges the i386 and x86_64 HPET code.

Prior to this commit, when we setup the HPET timers in x86_64, we did
the following:

	hpet_writel(HPET_TN_ENABLE | HPET_TN_PERIODIC | HPET_TN_SETVAL |
                    HPET_TN_32BIT, HPET_T0_CFG);

However after the i386/x86_64 HPET merge, we do the following:

	cfg = hpet_readl(HPET_Tn_CFG(timer));
	cfg |= HPET_TN_ENABLE | HPET_TN_PERIODIC |
			HPET_TN_SETVAL | HPET_TN_32BIT;
	hpet_writel(cfg, HPET_Tn_CFG(timer));

However on LS21s with HPET enabled in the BIOS, the HPET_T0_CFG register
boots with Level triggered interrupts (HPET_TN_LEVEL) enabled. This
causes the periodic interrupt to be not so periodic, and that results in
the boot time hang I reported earlier in the delay calibration.

My fix: Always disable HPET_TN_LEVEL when setting up periodic mode.

Recently I received a report about internal mic not working
(https://qa.mandriva.com/show_bug.cgi?id=44855#c193), this must be
related with the forced line in on pin 0x0e done with hp-m4 model. Thus
change the current quirk from STAC_HP_M4 to STAC_HP_DV5, later reported
to be fixed on a provided kernel with this change
(https://qa.mandriva.com/show_bug.cgi?id=44855#c196).

core_initcall routines run before the powerpc topology_init()
startup routine, which is a subsys_initcall, resulting in
failure of ps3_mm_add_memory() when CONFIG_NUMA=y.  When
ps3_mm_add_memory() fails the system will boot with just the
128 MiB of boot memory

06eccea6c3 powerpc/mm: Fix numa reserve bootmem page selection
Fix the powerpc NUMA reserve bootmem page selection logic.

commit 8f64e1f2d1 (powerpc: Reserve
in bootmem lmb reserved regions that cross NUMA nodes) changed
the logic for how the powerpc LMB reserved regions were converted
to bootmen reserved regions.  As the folowing discussion reports,
the new logic was not correct.

mark_reserved_regions_for_nid() goes through each LMB on the
system that specifies a reserved area.  It searches for
active regions that intersect with that LMB and are on the
specified node.  It attempts to bootmem-reserve only the area
where the active region and the reserved LMB intersect.  We
can not reserve things on other nodes as they may not have
bootmem structures allocated, yet.

We base the size of the bootmem reservation on two possible
things.  Normally, we just make the reservation start and
stop exactly at the start and end of the LMB.

However, the LMB reservations are not aware of NUMA nodes and
on occasion a single LMB may cross into several adjacent
active regions.  Those may even be on different NUMA nodes
and will require separate calls to the bootmem reserve
functions.  So, the bootmem reservation must be trimmed to
fit inside the current active region.

That's all fine and dandy, but we trim the reservation
in a page-aligned fashion.  That's bad because we start the
reservation at a non-page-aligned address: physbase.

The reservation may only span 2 bytes, but that those bytes
may span two pfns and cause a reserve_size of 2*PAGE_SIZE.

Take the case where you reserve 0x2 bytes at 0x0fff and
where the active region ends at 0x1000.  You'll jump into
that if() statment, but node_ar.end_pfn=0x1 and
start_pfn=0x0.  You'll end up with a reserve_size=0x1000,
and then call

  reserve_bootmem_node(node, physbase=0xfff, size=0x1000);

0x1000 may not be on the same node as 0xfff.  Oops.

In almost all the vm code, end_<anything> is not inclusive.
If you have an end_pfn of 0x1234, page 0x1234 is not
included in the range.  Using PFN_UP instead of the
(>> >> PAGE_SHIFT) will make this consistent with the other VM
code.

We also need to do math for the reserved size with physbase
instead of start_pfn.  node_ar.end_pfn << PAGE_SHIFT is
*precisely* the end of the node.  However,
(start_pfn << PAGE_SHIFT) is *NOT* precisely the beginning
of the reserved area.  That is, of course, physbase.
If we don't use physbase here, the reserve_size can be
made too large.
