2008-11-12MN10300: Handle misaligned SP-based operandsDavid Howells
Support misalignment handling for instructions that have kernel SP-based address operands, including fixing those that include IMM8 or IMM16 displacements. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Fix misaligned index-register addressing handlingDavid Howells
Fix misalignment handling for an address calculated from the sum of two registers. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Handle misaligned postinc-with-imm addressing mode correctlyDavid Howells
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: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Perform misalignment fixups of MOV_LccDavid Howells
Perform misalignment fixups of the MOV_Lcc instructions (move postinc memory to register and conditionally loop). Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Allow misalignment fixup in interrupt handlingDavid Howells
Allow misalignment fixup in interrupt handling in the MN10300 arch. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Fix register-postinc addressing misalignment handlingDavid Howells
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: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Extract the displacement from an insn correctly in misalignment fixupDavid Howells
Extract the displacement from an MN10300 instruction correctly in the misalignment fixup handler. The code should extract the displacement in LSB order, not MSB order. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Add further misalignment fixupsDavid Howells
Add further misalignment fixup support to the MN10300 arch, notably for ABS32 and SP+disp addressing. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Add built-in testing for misalignment handlerDavid Howells
Add configurable built-in testing for the MN10300 misalignment handler. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-11-12MN10300: Clean up the misalignment handler a littleDavid Howells
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: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The STACK_GROWSUP case of stack expansion was missing a test for 'prev', which got removed by commit cb8f488c33539f096580e202f5438a809195008f ("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.

2008-11-11ACPI: pci_link: remove acpi_irq_balance_set() interfaceBjorn Helgaas
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.

2008-11-11fujitsu-laptop: Add DMI callback for Lifebook S6420Tony Vroon
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.

2008-11-11ACPICA: Use spinlock for acpi_{en|dis}able_gpeAlexey Starikovskiy
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.

2008-11-11KVM: VMX: Set IGMT bit in EPT entrySheng Yang
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).
