Fix bugs for unlikely edge cases noticed by Douglas Gilbert: - When READ(6)/WRITE(6) sector count == 0, treat it as 256 sectors - For other READ(x)/WRITE(x), when sector count == 0, error. We don't support successfully completing zero-length transfers at this time.

Wrap ata_qc_complete() calls in EH context in spinlocks, to prevent races (mainly in ATAPI code paths).

As pointed out in the following thread, the CLOCK_TICK_RATE setting for IXP4xx is incorrect b/c the HW ignores the lowest 2 bits of the LATCH value. http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-August/030950.html Tnx to George Anziger and Egil Hjelmeland for finding the issue.

This keeps the kernel/cpuset.c routine update_cpu_domains() from invoking the sched.c routine partition_sched_domains() if the cpuset in question doesn't fall on node boundaries. I have boot tested this on an SN2, and with the help of a couple of ad hoc printk's, determined that it does indeed avoid calling the partition_sched_domains() routine on partial nodes. I did not directly verify that this avoids setting up bogus sched domains or avoids the oops that Hawkes saw. This patch imposes a silent artificial constraint on which cpusets can be used to define dynamic sched domains. This patch should allow proceeding with this new feature in 2.6.13 for the configurations in which it is useful (node alligned sched domains) while avoiding trying to setup sched domains in the less useful cases that can cause the kernel corruption and oops.

The code to detect IO links on Opteron would not check if the node had actually memory. This could lead to pci_bus_to_node returning an invalid node, which might cause crashes later when dma_alloc_coherent passes it to page_alloc_node(). The bug has been there forever but for some reason it is causing now crashes. Signed-off-by:

There's a "return the wrong SKB" error in the GL620A cable minidriver (for "usbnet") which can oops. This would not appear when talking Linux-to-Linux, only Linux-to-Windows (for recent Linuxes). Signed-off-by:

i386 floating-point exception handling has a bug that can cause error code 0 to be sent instead of the proper code during signal delivery. This is caused by unconditionally checking the IS and c1 bits from the FPU status word when they are not always relevant. The IS bit tells whether an exception is a stack fault and is only relevant when the exception is IE (invalid operation.) The C1 bit determines whether a stack fault is overflow or underflow and is only relevant when IS and IE are set. Signed-off-by:

either icu_data declaration for SMP case should be taken out of m32102.h, or its declarations for m32700ut and opsput should not be static for SMP. Patch does the latter - judging by comments in m32102.h it is intended to be non-static. Signed-off-by:
