bugzilla: #12363
commit 7cd5b08be3c489df11b559fef210b81133764ad4 added a second regression:
some Dell's and Compaq's lockup on boot. So we revert most of the code.
The ICH9 reboot issue remains in place and will need some more fixing... :-(

bffac3c593eba1f9da3efd0199e49ea6558a40ce has wrong values in the array.
Rather than correct the array, we can just use a bounds check and
perform the calculation specified in the comment. As a bonus, this will
not run off the end of the array if the device specifies an illegal

uids in namespaces other than init don't get a sysfs entry.
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().

ASoC supports both explicit codec drivers for AC97 devices and a simple
driver which uses the standard ALSA AC97 framework for codec support.
When used with the generic AC97 codec support that will provide the
ad hoc AC97 device for drivers like touchscreens to attach to so the
core shouldn't do so.

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.

Added the helper function snd_hda_multi_out_dig_cleanup() to clean up
the digital outputs with multi setup. This call is needed in cases
the codec supports multiple digital outputs as slaves. Otherwise the
slave widgets aren't properly cleaned up.
For a single digital output (e.g. in patch_conexant.c), this call isn't
needed.

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 b8ce33590687888ebb900d09557b8807c4539022, 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.

Change HP dv7 quirk: although reported to work with hp-m4 model
(https://bugzilla.novell.com/show_bug.cgi?id=445321), the original
report doesn't contain info about testing of internal microphone.
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).

Fix the powerpc NUMA reserve bootmem page selection logic.
commit 8f64e1f2d1e09267ac926e15090fd505c1c0cbcb (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.

When a non-wimax interface is looked up by the stack, a bad pointer is
