PAGE_MASK is an unsigned long, so using it to mask physical addresses on
i386 (which are 64-bit wide) leads to truncation.  This can result in
page->private of unrelated memory pages being modified, with disasterous
results.

Fix by not using PAGE_MASK for physical addresses; instead calculate
the correct value directly from PAGE_SIZE.  Also fix a similar BUG_ON().

KVM shadow page tables are always in pae mode, regardless of the guest
setting.  This means that a guest pde (mapping 4MB of memory) is mapped
to two shadow pdes (mapping 2MB each).

When the guest writes to a pte or pde, we intercept the write and emulate it.
We also remove any shadowed mappings corresponding to the write.  Since the
mmu did not account for the doubling in the number of pdes, it removed the
wrong entry, resulting in a mismatch between shadow page tables and guest
page tables, followed shortly by guest memory corruption.

This patch fixes the problem by detecting the special case of writing to
a non-pae pde and adjusting the address and number of shadow pdes zapped
accordingly.

All modern distributions have been setting these options to "y" for ages.
(additionally "n" cases have been obsoleted for few years).  Therefore use
DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer
needed CONFIG_IDEDMA_AUTO).  This fixes DMA support for rare configurations
where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used
to enable DMA support and which were forced to PIO mode by "ide: don't allow
DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch.  There is no
functionality loss because "ide=nodma" kernel option is still available.

For CONFIG_IDEDMA_{ICS,PCI}_AUTO=n and/or "ide=nodma" option the host/device
are not programmed for DMA and it is also explicitly disabled by ide_set_dma()
(->ide_dma_check returns "-1").  However the code responsible for manually
enabling DMA ("hdparm -d 1") has a bug which results in DMA being erroneously
enabled - ide_set_dma() incorrectly passes "0" return value to set_using_dma().
This may work if BIOS/firmware configured the host/device for DMA and chipset
allows independent configuration of DMA/PIO modes but won't work after suspend
and is generally unsafe on many chipsets (possibly including data corruption
if the same registers are used for DMA/PIO timings).

This patch fixes kernel bugzilla bug #8169 (piix host driver fixes for
setting PIO mode exposed the problem described above).  The side-effect of
the fix is that some rare configuration may be forced to PIO mode when DMA
mode was previously used - this is addressed by the next patch which removes
CONFIG_IDEDMA_{PCI,ICS}_AUTO config option completely.

Thanks goes out to Patrick Horn for reporting the issue, narrowing it down
to the specific commit and testing the fix.  Also thanks to Sergei Shtylyov
for help in debugging the problem.

The driver wrongly takes the address setup time into account when calculating
the PIO recovery time -- this leads to slight overclocking of the PIO modes 0
and 1 (so, the prayers failed to help, as usual :-).  Rework the code to be
calculating recovery clock count as a difference between the total cycle count
and the active count (we don't need to calculate the recovery time itself since
it's not specified for the PIO modes 0 to 2, and for modes 3 and 4 this formula
gives enough recovery time anyway in the chip's supported PCI frequency range).

This patch has been inspired by reading the datasheets and looking at what the
libata driver does; it has been compile-tested only (as usual :-) but anyway,
the new code gives the same or longer recovery times than the old one...

I finally found a dual core box, which survives suspend/resume without
crashing in the middle of nowhere. Sigh, I never figured out from the
code and the bug reports what's going on.

The observed hangs are caused by a stale state transition of the clock
event devices, which keeps the RCU synchronization away from completion,
when the non boot CPU is brought back up.

The suspend/resume in oneshot mode needs the similar care as the
periodic mode during suspend to RAM. My assumption that the state
transitions during the different shutdown/bringups of s2disk would go
through the periodic boot phase and then switch over to highres resp.
nohz mode were simply wrong.

Add the appropriate suspend / resume handling for the non periodic
modes.

This bug was seen on ppc64, but it could have occurred on any
architecture with a page size of 64k or above.  The problem is that in
fs/binfmt_elf.c:randomize_stack_top() randomizes the stack to within
0x7ff pages.  On 4k page machines, this is 8MB; on 64k page boxes, this
is 128MB.

The problem is that the new binary layout (selected in
arch_pick_mmap_layout) places the mapping segment 128MB or the stack
rlimit away from the top of the process memory, whichever is larger.  If
you chose an rlimit of less than 128MB (most defaults are in the 8Mb
range) then you can end up having your entire stack randomized away.

The fix is to make randomize_stack_top() only steal at most 8MB, which this
patch does.  However, I have to point out that even with this, your stack
rlimit might not be exactly what you get if it's > 128MB, because you're
still losing the random offset of up to 8MB.

The true fix should be to leave an explicit gap for the randomization plus
a buffer when determining mmap_base, but that would involve fixing all the
architectures.

The current NFS client congestion logic is severly broken, it marks the
backing device congested during each nfs_writepages() call but doesn't
mirror this in nfs_writepage() which makes for deadlocks.  Also it
implements its own waitqueue.

Replace this by a more regular congestion implementation that puts a cap on
the number of active writeback pages and uses the bdi congestion waitqueue.

Also always use an interruptible wait since it makes sense to be able to
SIGKILL the process even for mounts without 'intr'.
