ARM: pxa: fix page table corruption on resume

2011-01-03T15:18:59Z

Before this patch, the following error would sometimes occur after a resume on pxa3xx: /path/to/mm/memory.c:144: bad pmd 8040542e. The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.

ARM: it8152: add IT8152_LAST_IRQ definition to fix build error

The commit 6ac6b817f3f4c23c5febd960d8deb343e13af5f3 (ARM: pxa: encode IRQ number into .nr_irqs) removed definition of ITE_LAST_IRQ which caused the following build error: CC arch/arm/common/it8152.o arch/arm/common/it8152.c: In function 'it8152_init_irq': arch/arm/common/it8152.c:86: error: 'IT8152_LAST_IRQ' undeclared (first use in this function) arch/arm/common/it8152.c:86: error: (Each undeclared identifier is reported only once arch/arm/common/it8152.c:86: error: for each function it appears in.) make[2]: *** [arch/arm/common/it8152.o] Error 1 Defining the IT8152_LAST_IRQ in the arch/arm/include/hardware/it8152.c fixes the build.

arch/x86/oprofile/op_model_amd.c: Perform initialisation on a single CPU

2011-01-03T12:01:40Z

Disable preemption in init_ibs(). The function only checks the ibs capabilities and sets up pci devices (if necessary). It runs only on one cpu but operates with the local APIC and some MSRs, thus it is better to disable preemption.

KVM: i8259: initialize isr_ack

2011-01-02T09:52:48Z

isr_ack is never initialized. So, until the first PIC reset, interrupts may fail to be injected. This can cause Windows XP to fail to boot, as reported in the fallout from the fix to https://bugzilla.kernel.org/show_bug.cgi?id=21962.
