| * KVM: x86: fix lapic.timer_mode on restoreRadim Krčmář2015-06-161-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lapic.timer_mode was not properly initialized after migration, which broke few useful things, like login, by making every sleep eternal. Fix this by calling apic_update_lvtt in kvm_apic_post_state_restore. There are other slowpaths that update lvtt, so this patch makes sure something similar doesn't happen again by calling apic_update_lvtt after every modification.

Details: - fix handling of clock in chipco SSB driver. - fix two MIPS-specific #if conditions to correctly work for GCC 5.1. - fix damage to R6 pgtable bits done by XPA support. - fix possible crash due to unloading modules that contain statically defined platform devices. - fix disabling of the MSA ASE on context switch to also work correctly when a new thread/process has the CPU for the very first time. This is part of linux-next and has been beaten to death on Imagination's test farm. While things are not looking too grim this pull request also means the rate of fixes for 4.1 remains nearly constant so I'd not be unhappy if you'd delay the release" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MPI: MIPS: Fix compilation error with GCC 5.1 IRQCHIP: mips-gic: Don't nest calls to do_IRQ() MIPS: MSA: bugfix - disable MSA correctly for new threads/processes.

Turns out this error is because of missing ENDPROC for assembly code as suggested by Stephen Boyd <sboyd@codeaurora.org>. Let's fix the problem by adding ENDPROC in two places to sleep34xx.S. Let's also remove the now duplicate custom code for mode switching. This has been unnecessary since commit 6ebbf2ce437b ("ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+"). And let's also remove the comments about local variables, they are now just confusing after the ENDPROC. The reason why ENDPROC makes a difference is it sets .type and then the compiler knows what to do with the thumb bit as explained at: https://wiki.ubuntu.com/ARM/Thumb2PortingHowto Reported-by: Kevin Hilman <khilman@kernel.org> Tested-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
