2008-12-16x86: microcode_amd: remove (wrong) chipset deivce ID checksAndreas Herrmann
Impact: remove dead/incorrect code Currently there is no chipset specific ucode. The checks are incorrect anyway (e.g. pci device IDs are 16 bit and not 8 bit). Thus I remove the stuff for the time being and will reintroduce it if it's foreseeable that it is really needed.

Fix the preemption resume_kernel() routine by inverting the test to see whether interrupts are off (IM7 is all enabled, not all disabled). Furthermore, interrupts should be disabled on entry to resume_kernel() so that they're correctly set for jumping to restore_all() and doing the need reschedule test.

2008-12-10MN10300: Discard low-priority Tx interrupts when closing an on-chip serial portAkira Takeuchi
Discard low-prioriy Tx interrupts when closing an MN10300 on-chip serial port. The MN10300 on-chip serial port uses three interrupts to manage its serial ports: (1) A very high priority interrupt that drives virtual DMA for Rx. (2) A very high priority interrupt that drives virtual DMA for Tx. (3) A normal priority virtual interrupt that does the normal UART interrupt stuff and is shared between Rx and Tx. mn10300_serial_stop_tx() only disables the high priority Tx interrupt. It doesn't also disable the normal priority one because it is shared with Rx. However, the high priority interrupt may interrupt local_irq_disabled() sections, and so may have queued up a low priority virtual interrupt whilst the UART driver is asking for the Tx interrupt to be disabled. The result of this can be an oops when we try to process the interrupt in mn10300_serial_transmit_interrupt() as port->uart.info and port->uart.info->tty may have gone away. To deal with this, if either of those pointers is NULL, we make sure the high-priority Tx interrupt is disabled and discard the interrupt. The low priority interrupt is disabled by the mn10300_serial_pic irq_chip table.

Certain X11 servers such as the SIS server will only work if PCI mmap is implemented. This patch implements PCI mmap but to be on the same side so close to a release it only supports uncached mappings so performance will not be optimal for some uses such as framebuffers.

2008-12-09[IA64] SN: prevent IRQ retargetting in request_irq()John Keller
With the introduction of the generic affinity autoselector, irq_select_affinity(), IRQs are now being retargetted, using a default mask, via the request_irq() path. This results in all IRQs targetted at CPU 0. SN Altix assigns affinity in the SN PROM, and does not expect that to be changed as part of request_irq(). Set the IRQ_AFFINITY_SET flag to prevent request_irq() from resetting affinity. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary.

2008-12-07[ARM] Fix alignment fault handling for ARMv6 and later CPUsRussell King
On ARMv6 and later CPUs, it is possible for userspace processes to get stuck on a misaligned load or store due to the "ignore fault" setting; unlike previous CPUs, retrying the instruction without the 'A' bit set does not always cause the load to succeed. We have no real option but to default to fixing up alignment faults on these CPUs, and having the CPU fix up those misaligned accesses which it can.

2008-12-06[ARM] 5340/1: fix stack placement after noexecstack changesLennert Buytenhek
Commit 8ec53663d2698076468b3e1edc4e1b418bd54de3 ("[ARM] Improve non-executable support") added support for detecting non-executable stack binaries. One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

2008-12-05powerpc/virtex5: Fix Virtex5 machine check handlingGrant Likely
The 440x5 core in the Virtex5 uses the 440A type machine check (ie, they have MCSRR0/MCSRR1). They thus need to call the appropriate fixup function to hook the right variant of the exception. Without this, all machine checks become fatal due to loss of context when entering the exception handler.
