* MIPS: Alchemy: DB1200: Disable cascade IRQ in handlerManuel Lauss2011-09-21
| | | | | | | | | | | | Disable the cascade IRQ in the cascade handler. This is required to get the DB1300 working, and also gets rid of all spurious interrupts previously observed on the DB1200; so Config[OD] can be disabled again for better performance.

* MIPS: tlbex: Fix build error in R3000 code.Ralf Baechle2011-09-21
| | | | | | | | | | | | | Only some GCC versions such as gcc 4.2 notice that the variable wr in build_r3000_tlb_modify_handler is used uninitialized. When using one of those GCCs the build will fail due to -Werror. GCC 4.6 does not warn about the uninitialized use of wr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_signal() does __put_user() which can fault, resulting in a might_sleep() warning in down_read(&mm->mmap_sem) and a "scheduling while atomic" warning when mmap_sem is contented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the obvious error in board detection logic, because according to the TS's manual, the model is stored in the least three significant bits. For example the byte read on my ts-7300 is 0x23 and the detection then fails.

| | * | | ARM: cache: detect VIPT aliasing I-cache on ARMv6Will Deacon2011-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current cache detection code does not check for an aliasing I-cache if the D-cache is found to be VIPT aliasing. This patch fixes the problem by always checking for an aliasing I-cache on v6 and later. Signed-off-by: Will Deacon <will.deacon@arm.com>
| | * | | ARM: twd: register clockevents device before enabling PPIWill Deacon2011-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The smp_twd clockevents driver currently enables the local timer PPI before the clockevents device is registered. This can lead to a kernel panic if a spurious timer interrupt is generated before registration has completed since the kernel will treat it as an IPI timer. This patch moves the clockevents device registration before the IRQ unmasking so that we can always handle timer interrupts once they can occur.

| | * | | ARM: realview: ensure visibility of writes during resetWill Deacon2011-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The various reset routines in mach-realview rely on an FPGA to power-cycle the board after writing some magic runes to memory-mapped registers. This patch adds a dsb() following the writes, so that they become visible before we mdelay(1000) in the arch_reset code. Without this patch, the timeout would expire sporadically, causing the reset to fail. Signed-off-by: Will Deacon <will.deacon@arm.com>

It would be nice if these were consistent. This patch makes use of enum arm_pmu_type consistent, always using `type'. Related printks are updated, explicitly mentioning `type' also.

This patch changes the prototype of the stub, preventing possible build failures when CONFIG_CPU_HAS_PMU is not selected.
