2010-04-12MIPS: BCM63xx: Fix typo in cpu-feature-overrides file.Maxime Bizon
Fix typo: CONFIG_BCMCPU_IS_63xx does not exist; CONFIG_BCM63XX_CPU_63xx is the valid config option.

2010-04-12MIPS: BCM63xx: Add support for second uart.Maxime Bizon
The BCm63xx SOC has two uarts. Some boards use the second one for bluetooth. This patch changes platform device registration code to handle this. Changes to the UART driver were already merged in 6a2c7eabfd09ca7986bf96b8958a87ca041a19d8.

2010-04-12MIPS: Move signal trampolines off of the stack.David Daney
This is a follow on to the vdso patch. Since all processes now have signal trampolines permanently mapped, we can use those instead of putting the trampoline on the stack and invalidating the corresponding icache across all CPUs. We also get rid of a bunch of ICACHE_REFILLS_WORKAROUND_WAR code. [Ralf: GDB 7.1 which has the necessary modifications to allow backtracing over signal frames will supposedly be released tomorrow. The old signal frame format obsoleted by this patch exists in two variations, for sane processors and for those requiring ICACHE_REFILLS_WORKAROUND_WAR. So there was never a GDB which did support backtracing over signal frames on all MIPS systems. This convinved me this series should be applied and pushed upstream as soon as possible.] Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/974/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-04-12MIPS: Preliminary VDSODavid Daney
This is a preliminary patch to add a vdso to all user processes. Still missing are ELF headers and .eh_frame information. But it is enough to allow us to move signal trampolines off of the stack. Note that emulation of branch delay slots in the FPU emulator still requires the stack. We allocate a single page (the vdso) and write all possible signal trampolines into it. The stack is moved down by one page and the vdso is mapped into this space.

commit 6a985c6194017de2c062916ad1cd00dee0302c40 ([S390] s390: use change recording override for kernel mapping) deactivated the change bit recording for the kernel mapping to improve the performance. This works most of the time, but there are cases (e.g. kernel runs in home space, futex atomic compare xcmg) where we modify user memory with the kernel mapping instead of the user mapping. Instead of fixing these cases, this patch just deactivates change bit override to avoid future problems with other kernel code that might use the kernel mapping for user memory.

2010-04-09[S390] fix io_return critical section cleanupMartin Schwidefsky
If a machine check interrupts the io interrupt handler on one of the instructions between io_return and io_leave the critical section cleanup code will move the return psw to io_work_loop. By doing that the switch from the asynchronous interrupt stack to the process stack is skipped. If e.g. TIF_NEED_RESCHED is set things break because the scheduler is called with the asynchronous interrupts stack. Moving the psw back to io_return instead fixes the problem.

2010-04-09ARM: 6043/1: AT91 slow-clock resume: Don't wait for a disabled PLL to lockAnders Larsen
at91 slow-clock resume: Don't wait for a disabled PLL to lock. We run into this problem with the PLLB on the at91: ohci-at91 disables the PLLB when going to suspend. The slowclock code however tries to do the same: It saves the PLLB register value and when restoring the value during resume, it waits for the PLLB to lock again. However the PLL will never lock and the loop would run into its timeout because the slowclock code just stored and restored an empty register. This fixes the problem by only restoring PLLA/PLLB when they were enabled at suspend time.

2010-04-08perf: Fix unsafe frame rewinding with hot regs fetchingFrederic Weisbecker
When we fetch the hot regs and rewind to the nth caller, it might happen that we dereference a frame pointer outside the kernel stack boundaries, like in this example: perf_trace_sched_switch+0xd5/0x120 schedule+0x6b5/0x860 retint_careful+0xd/0x21 Since we directly dereference a userspace frame pointer here while rewinding behind retint_careful, this may end up in a crash. Fix this by simply using probe_kernel_address() when we rewind the frame pointer. This issue will have a much more proper fix in the next version of the perf_arch_fetch_caller_regs() API that will only need to rewind to the first caller.

2010-04-07frv: fix kernel/user segment handling in NOMMU modeDavid Howells
In NOMMU mode, the FRV segment handling is broken because KERNEL_DS == USER_DS. This causes tests of the following sort: /* don't pin down non-user-based iovecs */ if (segment_eq(get_fs(), KERNEL_DS)) return NULL; to malfunction. To fix this, make USER_DS the top of RAM instead of the top of the non-IO address space, and make KERNEL_DS one more than the top of the non-IO address space. Also get rid of FRV's __addr_ok() as nothing uses it.

2010-04-07x86/gart: Disable GART explicitly before initializationJoerg Roedel
If we boot into a crash-kernel the gart might still be enabled and its caches might be dirty. This can result in undefined behavior later. Fix it by explicitly disabling the gart hardware before initialization and flushing the caches after enablement. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2010-04-07Revert "x86: disable IOMMUs on kernel crash"Chris Wright
This effectively reverts commit 61d047be99757fd9b0af900d7abce9a13a337488. Disabling the IOMMU can potetially allow DMA transactions to complete without being translated. Leave it enabled, and allow crash kernel to do the IOMMU reinitialization properly.
