[PATCH] FUTEX_WAKE_OP: enhanced error handling

The code for FUTEX_WAKE_OP calls an arch callback,
futex_atomic_op_inuser().  That callback can return an error code, but
currently the caller assumes any error is EFAULT, and will try various
things to resolve the fault before eventually giving up with EFAULT
(regardless of the original error code).  This is not a theoretical case -
arch callbacks currently return -ENOSYS if the opcode they are given is
bogus.

This patch alters the code to detect non-EFAULT errors and return them
directly to the user.

Of course, whether -ENOSYS is the correct return value for the bogus opcode
case, or whether EINVAL would be more appropriate is another question.

[PATCH] aio: remove aio_max_nr accounting race

AIO was adding a new context's max requests to the global total before
testing if that resulting total was over the global limit.  This let
innocent tasks get their new limit tested along with a racing guilty task
that was crossing the limit.  This serializes the _nr accounting with a
spinlock It also switches to using unsigned long for the global totals.
Individual contexts are still limited to an unsigned int's worth of
requests by the syscall interface.

The problem and fix were verified with a simple program that spun creating
and destroying a context while holding on to another long lived context.
Before the patch a task creating a tiny context could get a spurious EAGAIN
if it raced with a task creating a very large context that overran the
limit.

pdev = platform_device_alloc("mydev", id);

ARRAY_SIZE(resources));
if (err == 0)

[PATCH] uml: build host-binaries with the native host arch again

When we were building complete binaries to get constants (such as ptrace
register layout on stack) from host userspace headers, we needed to make the
arch for building HOST binaries match our one: i.e.  on a 64bit system
compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit
ncurses.  Now we can revert that - that avoids problem with, say, menuconfig
and ncurses, on a system which can't compile well 32-bit programs.

[PATCH] uml: fix syscall stubs

Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.

Note: in syscall6 case I had to add one more instruction (i.e.  moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.

The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

Since we hold the cpu_control semaphore it shouldn't be any problem to access

The reason why cpu_up failed is simply that the cpu that was supposed to be

[PATCH] i386: LVT entries remaining unmasked on reboot

Excerpt from bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=5518

"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point.  As a result, BIOS ends up
bombarded with interrupts early on boot.  The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.

For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT.  The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case).  The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros.  Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.

machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"

[PATCH] ppc32: Dump error status for both PLB segments on 440SP

The PowerPC 440SP SoC has two Processor Local Bus (PLB) segments (a
high-throughput segment and a low-latency segment).  Fix our PLB register
definitions to cope with this, and add code to dump the status of both
segments when a machine check occurs.

[PATCH] ppc32: Allow ERPN for early serial to depend on CPU type

The PowerPC 440SPe supports up to 16 GB of RAM, and therefore its IO registers
are at 0x4_xxxx_xxxx instead of being at 0x1_xxxx_xxxx like most other PPC 440
chips.  To allow for this, this patch moves the definition of the ERPN used
for mapping UART0 from being hard-coded in the head_44x.S assembly code to
being defined in ibm44x.h.

This may improve performance for those devices so equipped.  This will be
the default behaviour for IS_CYCLONE and IS_TORNADO devices.  Additionally,
it can be enabled/disabled individually for up to MAX_UNITS number of

[PATCH] slab: Use same schedule timeout for all cpus in cache_reap

Chen noticed that cache_reap uses REAPTIMEOUT_CPUC+smp_processor_id() as
the timeout for rescheduling.

The "+smp_processor_id()" part is wrong, the timeout should be identical
for all cpus: start_cpu_timer already adds a cpu dependant offset to avoid
any clustering.

[PATCH] slab: don't BUG on duplicated cache

slab presently goes BUG if someone tries to register an already-registered
cache.

But this can happen if the user accidentally loads a module which is already
statically linked into the kernel.  Nuking the kernel is rather a harsh
reaction.

Change it into a warning, and just fail the kmem_cache_alloc() attempt.  If
the module is well-behaved, the modprobe will fail and all is well.

Notes:

- Swaps the ranking of cache_chain_sem and lock_cpu_hotplug().  Doesn't seem
  important.
