2013-02-12ARM: exynos: move exynos4210-combiner to drivers/irqchipRob Herring
Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init for GIC init). This commit split the irqchip initialization into 2 calls to of_irq_init. This does not work because of_irq_init requires interrupt parents to be in the match list. Rather than reverting exynos changes, make it do the proper thing by using IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.

2013-01-31MIPS: Function tracer: Fix broken function tracingAl Cooper
Function tracing is currently broken for all 32 bit MIPS platforms. When tracing is enabled, the kernel immediately hangs on boot. This is a result of commit b732d439cb43336cd6d7e804ecb2c81193ef63b0 that changes the kernel/trace/Kconfig file so that is no longer forces FRAME_POINTER when FUNCTION_TRACING is enabled. MIPS frame pointers are generally considered to be useless because they cannot be used to unwind the stack. Unfortunately the MIPS function tracing code has bugs that are masked by the use of frame pointers. This commit fixes the bugs so that MIPS frame pointers don't need to be enabled. The bugs are a result of the odd calling sequence used to call the trace routine. This calling sequence is inserted into every traceable function when the tracing CONFIG option is enabled. This sequence is generated for 32bit MIPS platforms by the compiler via the "-pg" flag. Part of the sequence is "addiu sp,sp,-8" in the delay slot after every call to the trace routine "_mcount" (some legacy thing where 2 arguments used to be pushed on the stack). The _mcount routine is expected to adjust the sp by +8 before returning. So when not disabled, the original jalr and addiu will be there, so _mcount has to adjust sp. The problem is that when tracing is disabled for a function, the "jalr _mcount" instruction is replaced with a nop, but the "addiu sp,sp,-8" is still executed and the stack pointer is left trashed. When frame pointers are enabled the problem is masked because any access to the stack is done through the frame pointer and the stack pointer is restored from the frame pointer when the function returns. This patch writes two nops starting at the address of the "jalr _mcount" instruction whenever tracing is disabled. This means that the "addiu sp,sp.-8" will be converted to a nop along with the "jalr". When disabled, there will be two nops. This is SMP safe because the first time this happens is during ftrace_init() which is before any other processor has been started. Subsequent calls to enable/disable tracing when other CPUs ARE running will still be safe because the enable will only change the first nop to a "jalr" and the disable, while writing 2 nops, will only be changing the "jalr". This patch also stops using stop_machine() to call the tracer enable/disable routines and calls them directly because the routines are SMP safe. When the kernel first boots we have to be able to handle the gcc generated jalr, addui sequence until ftrace_init gets a chance to run and change the sequence. At this point mcount just adjusts the stack and returns. When ftrace_init runs, we convert the jalr/addui to nops. Then whenever tracing is enabled we convert the first nop to a "jalr mcount+8". The mcount+8 entry point skips the stack adjust.

Commit d3ce88431892 "MIPS: Fix modpost error in modules attepting to use virt_addr_valid()" moved __virt_addr_valid() from a macro in a header file to a function in ioremap.c. But ioremap.c is only compiled for MIPS 32, and not for MIPS 64. When compiling for my yeeloong2, which supposedly supports hibernation, which compiles kernel/power/snapshot.c which calls virt_addr_valid(), I got this error: LD init/built-in.o kernel/built-in.o: In function `memory_bm_free': snapshot.c:(.text+0x4c9c4): undefined reference to `__virt_addr_valid' snapshot.c:(.text+0x4ca58): undefined reference to `__virt_addr_valid' kernel/built-in.o: In function `snapshot_write_next': (.text+0x4e44c): undefined reference to `__virt_addr_valid' kernel/built-in.o: In function `snapshot_write_next': (.text+0x4e890): undefined reference to `__virt_addr_valid' make[1]: *** [vmlinux] Error 1 make: *** [sub-make] Error 2 I suspect that __virt_addr_valid() is fine for mips 64.

2013-01-30efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming
Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

2013-01-29ARM: S3C24XX: transform irq handling into a declarative formHeiko Stuebner
The irqs available on the machine and even the bit settings in the irq registers differ a lot through all the s3c24xx subarchitectures. This results in each subarch having its own irq init which adds its specific irqs to the base ones created in plat-s3c24xx/irq.c. This of course makes a future move to devicetree hard to implement. Therefore this patch transforms the base irq handling to a declarative style, where the irq types as well as its parent/child relationship gets read from a predefined datastructure, which later on can hopefully be easily represented in devicetree too. It should also be easy to include the subarch specific irqs here in later patches, reducing code size and duplication. It should not affect anything outside of the file, as the original irq numbers and their handling are preserved (hopefully) correctly.

2013-01-29x86, efi: remove attribute check from setup_efi_pciMaarten Lankhorst
It looks like the original commit that copied the rom contents from efi always copied the rom, and the fixup in setup_efi_pci from commit 886d751a2ea99a160 ("x86, efi: correct precedence of operators in setup_efi_pci") broke that. This resulted in macbook pro's no longer finding the rom images, and thus not being able to use the radeon card any more. The solution is to just remove the check for now, and always copy the rom if available.
