8528b0f1de Clear spurious irq stat information when adding irq handler
Any newly added irq handler may obviously make any old spurious irq
status invalid, since the new handler may well be the thing that is
supposed to handle any interrupts that came in.

So just clear the statistics when adding handlers.

1b5180b651 [PATCH] notifiers: fix blocking_notifier_call_chain() scalability
while lock-profiling the -rt kernel i noticed weird contention during
mmap-intense workloads, and the tracer showed the following gem, in one
of our MM hotpaths:

 threaded-2771  1....   65us : sys_munmap (sysenter_do_call)
 threaded-2771  1....   66us : profile_munmap (sys_munmap)
 threaded-2771  1....   66us : blocking_notifier_call_chain (profile_munmap)
 threaded-2771  1....   66us : rt_down_read (blocking_notifier_call_chain)

ouch! a global rw-semaphore taken in one of the most performance-
sensitive codepaths of the kernel.  And i dont even have oprofile
enabled! All distro kernels have CONFIG_PROFILING enabled, so this
scalability problem affects the majority of Linux users.

The fix is to enhance blocking_notifier_call_chain() to only take the
lock if there appears to be work on the call-chain.

With this patch applied i get nicely saturated system, and much higher
munmap performance, on SMP systems.

And as a bonus this also fixes a similar scalability bottleneck in the
thread-exit codepath: profile_task_exit() ...

95543179f1 [PATCH] elevator: move clearing of unplug flag earlier
A flag was recently added to the elevator code to avoid
performing an unplug when reuests are being re-queued.
The goal of this flag was to avoid a deep recursion that
can occur when re-queueing requests after a SCSI device/host
reset.  See http://lkml.org/lkml/2006/5/17/254

However, that fix added the flag near the bottom of a case
statement, where an earlier break (in an if statement) could
transport one out of the case, without setting the flag.
This patch sets the flag earlier in the case statement.

I re-discovered the deep recursion recently during testing;
I was told that it was a known problem, and the fix to it was
in the kernel I was testing. Indeed it was ... but it didn't
fix the bug. With the patch below, I no longer see the bug.

ac8be95504 [MIPS] SMTC: Instant IPI replay.
SMTC pseudo-interrupts between TCs are deferred and queued if the target
TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these
queued IPIs were serviced on return to user mode, or on entry into the
kernel idle loop. The INSTANT_REPLAY option dispatches them as part of
local_irq_restore() processing, which adds runtime overhead (hence the
option to turn it off), but ensures that IPIs are handled promptly even
under heavy I/O interrupt load.

de14569f94 [PATCH] resierfs: avoid tail packing if an inode was ever mmapped
This patch fixes a confusion reiserfs has for a long time.

On release file operation reiserfs used to try to pack file data stored in
last incomplete page of some files into metadata blocks.  After packing the
page got cleared with clear_page_dirty.  It did not take into account that
the page may be mmaped into other process's address space.  Recent
replacement for clear_page_dirty cancel_dirty_page found the confusion with
sanity check that page has to be not mapped.

The patch fixes the confusion by making reiserfs avoid tail packing if an
inode was ever mmapped.  reiserfs_mmap and reiserfs_file_release are
serialized with mutex in reiserfs specific inode.  reiserfs_mmap locks the
mutex and sets a bit in reiserfs specific inode flags.
reiserfs_file_release checks the bit having the mutex locked.  If bit is
set - tail packing is avoided.  This eliminates a possibility that mmapped
page gets cancel_page_dirty-ed.

30150f8d7b [PATCH] mbind: restrict nodes to the currently allowed cpuset
Currently one can specify an arbitrary node mask to mbind that includes
nodes not allowed.  If that is done with an interleave policy then we will
go around all the nodes.  Those outside of the currently allowed cpuset
will be redirected to the border nodes.  Interleave will then create
imbalances at the borders of the cpuset.

This patch restricts the nodes to the currently allowed cpuset.

fc3dffe121 [PATCH] KVM: fix bogus pagefault on writable pages
If a page is marked as dirty in the guest pte, set_pte_common() can set the
writable bit on newly-instantiated shadow pte.  This optimization avoids
a write fault after the initial read fault.

However, if a write fault instantiates the pte, fix_write_pf() incorrectly
reports the fault as a guest page fault, and the guest oopses on what appears
to be a correctly-mapped page.

Fix is to detect the condition and only report a guest page fault on a user
access to a kernel page.

With the fix, a kvm guest can survive a whole night of running the kernel
hacker's screensaver (make -j9 in a loop).

038e51de2e [PATCH] KVM: x86 emulator: fix bit string instructions
The various bit string instructions (bts, btc, etc.) fail to adjust the
address correctly if the bit address is beyond BITS_PER_LONG.

This bug creeped in as the emulator originally relied on cr2 to contain the
memory address; however we now decode it from the mod r/m bits, and must
adjust the offset to account for large bit indices.

The patch is rather large because it switches src and dst decoding around, so
that the bit index is available when decoding the memory address.

This fixes workloads like the FC5 installer.

cccf748b81 [PATCH] KVM: fix race between mmio reads and injected interrupts
The kvm mmio read path looks like:

 1. guest read faults
 2. kvm emulates read, calls emulator_read_emulated()
 3. fails as a read requires userspace help
 4. exit to userspace
 5. userspace emulates read, kvm sets vcpu->mmio_read_completed
 6. re-enter guest, fault again
 7. kvm emulates read, calls emulator_read_emulated()
 8. succeeds as vcpu->mmio_read_emulated is set
 9. instruction completes and guest is resumed

A problem surfaces if the userspace exit (step 5) also requests an interrupt
injection.  In that case, the guest does not re-execute the original
instruction, but the interrupt handler.  The next time an mmio read is
exectued (likely for a different address), step 3 will find
vcpu->mmio_read_completed set and return the value read for the original
instruction.

The problem manifested itself in a few annoying ways:
- little squares appear randomly on console when switching virtual terminals
- ne2000 fails under nfs read load
- rtl8139 complains about "pci errors" even though the device model is
  incapable of issuing them.

Fix by skipping interrupt injection if an mmio read is pending.

A better fix is to avoid re-entry into the guest, and re-emulating immediately
instead.  However that's a bit more complex.

58d9ce7d75 [PATCH] Revert nmi_known_cpu() check during boot option parsing
Commit f2802e7f57 and its x86 version
(b7471c6da9) adds nmi_known_cpu() check
while parsing boot options in x86_64 and i386.

With that, "nmi_watchdog=2" stops working for me on Intel Core 2 CPU
based system.

The problem is, setup_nmi_watchdog is called while parsing the boot
option and identify_cpu is not done yet.  So, the return value of
nmi_known_cpu() is not valid at this point.

So revert that check.  This should not have any adverse effect as the
nmi_known_cpu() check is done again later in enable_lapic_nmi_watchdog().

We need to export phy_ethtool_gset and phy_ethtool_sset to allow drivers that
use these functions to be built as modules.

d08d283974 modify 3c589_cs to be SMP safe
1. EL3WINDOW is always 1 when lock is not held.

2. The second argument of el3_interrupt is 'void *dev_id',
not 'struct el3_private *lp'.

9ee79a3d37 [PATCH] x86: fix PDA variables to work during boot
The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.
