ALSA Harmony was resetting the capture position when
preparing the capture substream, which it shouldn't do.
This should fix the problem.Signed-off-by: Stuart Brady
ALSA Harmony should no longer play junk (left in the buffers
from a previous stream) at the start of a new stream.Implement the monitor mixer channel for ALSA Harmony.
Also prevent snd_harmony_volume_get from returning negative values.

Take into account nullified insn and lock functions for profiling
This is needed at the end of functions; it is typical that the return
branch nullifies the next insn, which is in the next function. This
causes profiling data to show up against the "wrong" function.We also count lock times against the locker. This is consistent with
other architectures.Signed-off-by: Randolph Chung

Fix card-mode Dino crashes on 725 (and probably other Snake) systems.
Dino was coming up in fatal mode after a warm reboot. Resetting Dino
brings it out of fatal mode, so do that if the status register indicates
we're in fatal mode. Since this was never observed on any later systems,
I presume firmware does this for us on those.Signed-off-by: Matthew Wilcox

From: Joel Soete
Signed-off-by: Grant GrundlerExplain why we need insert_resource() instead of request_resource().
Fundementally, this is more convoluted for ccio driver because of
o legacy (HP-PB) transperant bridges.
o support for MMIO behind card-mode Dino (PCI)
o support for above bridges without ccio in the boxSBA driver doesn't have to worry about those issues.

2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries
Previous code cleared the valid flag a pdir entry but it did NOT
guarantee this change was visible to the PDIR before writing
the PCOM register. Ie the SBA could pick up a stale entry if
the write happened to hit the SBA before the cacheline was flushed
from the cache.Long term, I think I want to make this a compile time flag.
Developement tree should enable anal pdir checking by default
and Debian can disable it with either a CONFIG option
or one-line patch. fdc/sync options can only negatively affect
performance though I haven't measure how much yet.
If someone can run netperf TCP_RR across gige and compare
-pa1 and -pa2, that would be sufficient.Cleaned up the use of "fdc" to make sure it's using "kernel"
space id (specify sr0 but maps to sr4-7). It seems a bit fragile
to assume "sr1" gets loaded with KERNEL_SPACE which is how the
code works today.Tested on 32 and 64-bit SMP kernels on j6k.

2.6.12-rc4-pa2 fix 32-bit support for Astro platforms
o Since my last SBA code change, SBA could allocate more than 1GB of IOVA
space on Astro boxes with more than 1GB of RAM when running 32-bit kernel.
This is bad since IOMMU can only talk to the first 1GB at most.
Kudos to jejb for quickly spotting that bug.o jejb also noted SBA should *always* reject DMA masks > 32-bits since
DMA-mapping.txt indicates caller should try again with 32-bits.o off-by-one error when comparing the mask to IOVA space size.

When I originally moved exit_itimers into __exit_signal, that was the only
place where we could reliably know it was the last thread in the group
dying, without races. Since then we've gotten the signal_struct.live
counter, and do_exit can reliably do group-wide cleanup work.This patch moves the call to do_exit, where it's made without locks. This
avoids the deadlock issues that the old __exit_signal code's comment talks
about, and the one that Oleg found recently with process CPU timers.[ This replaces e03d13e985d48ac4885382c9e3b1510c78bd047f, which is why
it was just reverted. ]Signed-off-by: Roland McGrath

Revert commit e03d13e985d48ac4885382c9e3b1510c78bd047f, to be replaced
by a much nicer fix from Roland. -
AMD recently discovered that on some hardware, there is a race condition
possible when a C-state change request goes onto the bus at the same
time as a P-state change request.Both requests happen, but the southbridge hardware only acknowledges the
C-state change. The PowerNow! driver is then stuck in a loop, waiting
for the P-state change acknowledgement. The driver eventually times
out, but can no longer perform P-state changes.It turns out the solution is to resend the P-state change, which the
southbridge will acknowledge normally.Thanks to Johannes Winkelmann for reporting this and testing the fix.

This fixes a stupid typo bug in the iSeries hash table code.
When we place a hash PTE in the secondary bucket, instead of setting the
SECONDARY flag bit, as we should, we (redundantly) set the VALID flag.This was introduced with the patch abolishing bitfields from the hash
table code. Mea culpa, oops. It hasn't been noticed until now because
in practice we don't hit the secondary bucket terribly often.Signed-off-by: David Gibson

Signed-off-by: Linus Torvalds -
While working on 64K pages, I found this little buglet in our
update_mmu_cache() implementation.The code calls __hash_page() passing it an "access" parameter (the type
of access that triggers the hash) containing the bits _PAGE_RW and
_PAGE_USER of the linux PTE. The latter is useless in this case and the
former is wrong. In fact, if we have a writeable PTE and we pass
_PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty
that way, by hash faulting !dirty) which is not what we want.In fact, the correct fix is to always pass 0. That means that only
read-only or already dirty read write PTEs will be preloaded. The
(hopefully rare) case of a non dirty read write PTE can't be preloaded
this way, it will have to fault in hash_page on the actual access.Signed-off-by: Benjamin Herrenschmidt

This fixes a typo in the div128_by_32 function used in the timekeeping

icmp_send doesn't use skb->sk at all so even if skb->sk has already
been freed it can't cause crash there (it would've crashed somewhere
else first, e.g., ip_queue_xmit).I found a double-free on an skb that could explain this though.
dccp_sendmsg and dccp_write_xmit are a little confused as to what
should free the packet when something goes wrong. Sometimes they
both go for the ball and end up in each other's way.This patch makes dccp_write_xmit always free the packet no matter
what. This makes sense since dccp_transmit_skb which in turn comes
from the fact that ip_queue_xmit always frees the packet.Signed-off-by: Herbert Xu

This introduces a limit parameter to the core bootmem allocator; The new
parameter indicates that physical memory allocated by the bootmem
allocator should be within the requested limit.We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit,
alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit
is the only api used for swiotlb.The existing alloc_bootmem_low_pages() api could instead have been
changed and made to pass right limit to the core allocator. But that
would make the patch more intrusive for 2.6.14, as other arches use
alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a
cleanup.With this, swiotlb gets memory within 4G for both x86_64 and ia64
arches.Signed-off-by: Yasunori Goto
