On stock 2.6.37-rc4, running:
# mount lilith:/export /mnt/lilith
# find /mnt/lilith/ -type f -print0 | xargs -0 file
crashes the machine fairly quickly under Xen. Often it results in oops
messages, but the couple of times I tried just now, it just hung quietly
and made Xen print some rude messages:
(XEN) mm.c:2389:d80 Bad type (saw 7400000000000001 != exp
3000000000000000) for mfn 1d7058 (pfn 18fa7)
(XEN) mm.c:964:d80 Attempt to create linear p.t. with write perms
(XEN) mm.c:2389:d80 Bad type (saw 7400000000000010 != exp
1000000000000000) for mfn 1d2e04 (pfn 1d1fb)
(XEN) mm.c:2965:d80 Error while pinning mfn 1d2e04
Which means the domain tried to map a pagetable page RW, which would
allow it to map arbitrary memory, so Xen stopped it. This is because
vm_unmap_ram() left some pages mapped in the vmalloc area after NFS had
finished with them, and those pages got recycled as pagetable pages
while still having these RW aliases.
Removing those mappings immediately removes the Xen-visible aliases, and
so it has no problem with those pages being reused as pagetable pages.
Deferring the TLB flush doesn't upset Xen because it can flush the TLB
itself as needed to maintain its invariants.
When unmapping a region in the vmalloc space, clear the ptes
immediately. There's no point in deferring this because there's no
amortization benefit.
The TLBs are left dirty, and they are flushed lazily to amortize the
cost of the IPIs.
This specific motivation for this patch is an oops-causing regression
since 2.6.36 when using NFS under Xen, triggered by the NFS client's use
of vm_map_ram() introduced in 56e4ebf877b60 ("NFS: readdir with vmapped
pages") . XFS also uses vm_map_ram() and could cause similar problems.

The console semaphore must be held while the OMAP UART devices are
disabled, lest a console write cause an ARM abort (and a kernel crash)
when the underlying console device is inaccessible. These crashes
only occur when the console is on one of the OMAP internal serial
ports.
While this problem has been latent in the PM idle loop for some time,
the crash was not triggerable with an unmodified kernel until commit
6f251e9db1093c187addc309b5f2f7fe3efd2995 ("OMAP: UART: omap_device
conversions, remove implicit 8520 assumptions"). After this patch, a
console write often occurs after the console UART has been disabled in
the idle loop, crashing the system. Several users have encountered
this bug:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg38396.html
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36602.html
The same commit also introduced new code that disabled the UARTs
during init, in omap_serial_init_port(). The kernel will also crash
in this code when earlyconsole and extra debugging is enabled:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36411.html
The minimal fix for the -rc series is to hold the console semaphore
while the OMAP UARTs are disabled. This is a somewhat overbroad fix,
since the console may not be located on an OMAP UART, as is the case
with the GPMC UART on Zoom3. While it is technically possible to
determine which devices the console or earlyconsole is actually
running on, it is not a trivial problem to solve, and the code to do
so is not really appropriate for the -rc series.
The right long-term fix is to ensure that no code outside of the OMAP
serial driver can disable an OMAP UART. As I understand it, code to
implement this is under development by TI.

Add additional check to omap_uart_resume_idle() so that only
enabled (specifically, idle-enabled) UARTs are allowed to resume.
This matches the existing check in prepare idle.
Without this patch, the system will hang if a board is
configured to register only some uarts instead of all of
them and PM is enabled.

This leads to a Kconfig dep inversion, x86 selects PERF_EVENT (due to
a hw_breakpoint dep) but doesn't unconditionally provide
HAVE_PERF_EVENT.
(This can cause build failures on M386/M486 kernel .config's.)

In a kvm virt guests, the perf counters are not emulated. Instead they
return zero on a rdmsrl. The perf nmi handler uses the fact that crossing
a zero means the counter overflowed (for those counters that do not have
specific interrupt bits). Therefore on kvm guests, perf will swallow all
NMIs thinking the counters overflowed.
This causes problems for subsystems like kgdb which needs NMIs to do its
magic. This problem was discovered by running kgdb tests.
The solution is to write garbage into a perf counter during the
initialization and hopefully reading back the same number. On kvm
guests, the value will be read back as zero and we disable perf as
a result.

This patch for SGI UV systems addresses a problem whereby
interrupt transactions being looped back from a local IOH,
through the hub to a local CPU can (erroneously) conflict with
IO port operations and other transactions.
To workaound this we set a high bit in the APIC IDs used for
interrupts. This bit appears to be ignored by the sockets, but
it avoids the conflict in the hub.

Found a NUMA system that doesn't have RAM installed at the first

| x86: Spread tlb flush vector between nodes
It turns out when first socket is not online it could have cpus on
node1 tlb_offset set to bigger than NUM_INVALIDATE_TLB_VECTORS.
That could affect systems like 4 sockets, but socket 2 doesn't
have installed, sockets 3 will get too big tlb_offset.
Need to use real online node idx.

Prevent kprobes to probe on save_args() since this function
will be called from breakpoint exception handler. That will
cause infinit loop on breakpoint handling.

When a single step exception fires, the trap bits, used to
signal hardware breakpoints, are in a random state.
These trap bits might be set if another exception will follow,
like a breakpoint in the next instruction, or a watchpoint in the
previous one. Or there can be any junk there.
So if we handle these trap bits during the single step exception,
we are going to handle an exception twice, or we are going to
handle junk.
Just ignore them in this case.

When running ktest.pl randconfig tests, I would sometimes trigger
a lockdep annotation bug (possible reason: unannotated irqs-on).
This triggering happened right after function tracer self test was
executed. After doing a config bisect I found that this was caused with
having function tracer, paravirt guest, prove locking, and rcu torture
all enabled.
The rcu torture just enhanced the likelyhood of triggering the bug.
Prove locking was needed, since it was the thing that was bugging.
Function tracer would trace and disable interrupts in all sorts
of funny places.
paravirt guest would turn arch_local_irq_* into functions that would
be traced.
Besides the fact that tracing arch_local_irq_* is just a bad idea,
this is what is happening.
The bug happened simply in the local_irq_restore() code:
if (raw_irqs_disabled_flags(flags)) { \
raw_local_irq_restore(flags); \
trace_hardirqs_off(); \
} else { \
trace_hardirqs_on(); \
raw_local_irq_restore(flags); \
} \
The raw_local_irq_restore() was defined as arch_local_irq_restore().
Now imagine, we are about to enable interrupts. We go into the else
case and call trace_hardirqs_on() which tells lockdep that we are enabling
interrupts, so it sets the current->hardirqs_enabled = 1.
Then we call raw_local_irq_restore() which calls arch_local_irq_restore()
which gets traced!
Now in the function tracer we disable interrupts with local_irq_save().
This is fine, but flags is stored that we have interrupts disabled.
When the function tracer calls local_irq_restore() it does it, but this
time with flags set as disabled, so we go into the if () path.
This keeps interrupts disabled and calls trace_hardirqs_off() which
sets current->hardirqs_enabled = 0.
When the tracer is finished and proceeds with the original code,
we enable interrupts but leave current->hardirqs_enabled as 0. Which
now breaks lockdeps internal processing.

On each machine check all registers are revalidated. The save area for
the clock comparator however only contains the upper most seven bytes
of the former contents, if valid.
Therefore the machine check handler uses a store clock instruction to
get the current time and writes that to the clock comparator register
which in turn will generate an immediate timer interrupt.
However within the lowcore the expected time of the next timer
interrupt is stored. If the interrupt happens before that time the
handler won't be called. In turn the clock comparator won't be
reprogrammed and therefore the interrupt condition stays pending which
causes an interrupt loop until the expected time is reached.
On NOHZ machines this can result in unresponsive machines since the
time of the next expected interrupted can be a couple of days in the
future.
To fix this just revalidate the clock comparator register with the
expected value.
In addition the special handling for udelay must be changed as well.

The PLLC2 clock was utilizing the same sort of enable/disable without
regard to usecount approach that the FSIDIV clock was when being used as
a PLL pass-through. This forces the enable/disable through the clock
framework, which now prevents the clock from being ripped out or modified
underneath users that have an existing handle on it.

We now:
* check for a v3 controller before setting 8-bit bus width
* offer a callback for platform code to switch to 8-bit mode, which
allows non-v3 controllers to support it
* rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify
that the board designers have indeed brought out all the pins for
8-bit to the slot.
We were previously relying only on whether the *controller* supported
8-bit, which doesn't tell us anything about the pin configuration in
the board design.
This fixes the MMC card regression reported by Maxim Levitsky here:
http://thread.gmane.org/gmane.linux.kernel.mmc/4336
by no longer assuming that 8-bit works by default.

Don't rewrite clock config in UCON preconfigured by
bootloader. No need to set 10th bit in UCON because
[11:10] 2'b00 means source clock is PCLK too.
If set, console does not work if bootloader
has preconfigured [11:10] with 2'b00.
If not set, console works with any bootloader
config value (2'bxx).
More information about clock setup in UCON is available
in "S3C6410X RISC Microprocessor User's Manual,
Revision 1.20" p. 31-13 (Chapter 31.6.2
UART CONTROL REGISTER).
