Correctly handle misalignment in MOV instructions with postinc-with-immediate addressing mode operands. In these, the immediate value is the increment to be applied the address register, not the displacement to the address. Signed-off-by:

Fix misalignment handling of operands with register postincrement addressing. The flag to indicate that postincrement is required should not be interpreted as an specification of a value to be added to the address. Also add BUGs to catch unimplemented parameter markings in the opcodes table. Signed-off-by:

Clean up the MN10300 misalignment handler a little by: (1) Use ilog2() rather than doing implementing log2() locally. (2) Make format_tbl[] const and static. (3) Making the debugging prints more consistent. Signed-off-by:

The STACK_GROWSUP case of stack expansion was missing a test for 'prev', which got removed by commit cb8f488c ("mmap.c: deinline a few functions") by mistake. I found my original email in "sent" folder. The patch in that mail does NOT remove !prev. That change had beed added by someone else. Ok, I think we are not much interested in who did it, let's fix it for good. [ "It looks like this was caused by me fixing rejects. That was the fancy include-lots-of-context-so-it-wont-apply patch." - akpm ] Reported-and-bisected-by:

This removes the acpi_irq_balance_set() interface from the PCI interrupt link driver. x86 used acpi_irq_balance_set() to tell the PCI interrupt link driver to configure links to minimize IRQ sharing. But the link driver can easily figure out whether to turn on IRQ balancing based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of that external interface. It's better for the driver to figure this out at init-time. If we set it externally via the x86 code, the interface reduces modularity, and we depend on the fact that acpi_process_madt() happens before we process the kernel command line. Signed-off-by:

The Lifebook S6420 is the ICH9M-based follow-up to the S6410. The application panel contains the following keys: lock, mobility center, eco, info. Whilst key 4 might be more appropriate for help then key 2, I've done things the S6410 way. I can confirm that backlight control is functional, and that the lock key activates the Gnome screensaver as expected. Signed-off-by:

Disabling gpe might interfere with gpe detection/handling, thus producing "interrupt not handled" errors. Ironically, disabling of GPE from interrupt context is already under spinlock, so only userspace needs to start using it. Signed-off-by:

There is a potential issue that, when guest using pagetable without vmexit when EPT enabled, guest would use PAT/PCD/PWT bits to index PAT msr for it's memory, which would be inconsistent with host side and would cause host MCE due to inconsistent cache attribute. The patch set IGMT bit in EPT entry to ignore guest PAT and use WB as default memory type to protect host (notice that all memory mapped by KVM should be WB). Signed-off-by:

The page fault path can use two rmap_desc structures, if: - walk_addr's dirty pte update allocates one rmap_desc. - mmu_lock is dropped, sptes are zapped resulting in rmap_desc being freed. - fetch->mmu_set_spte allocates another rmap_desc. Increase to 4 for safety. Signed-off-by:
