* UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)David Howells2012-10-041-6/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other arches), but there is one in asm-generic. This means that: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/include/asm-$(SRCARCH)/kvm_para.h \ $(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),) header-y += kvm_para.h endif gets it wrong because it is invoked twice during the header installation - and on the second occasion, asm-generic/kvm_para.h has been installed in usr/, thus triggering a attempt to install asm-m68k/kvm_para.h which will fail. There are three headers with this sort of conditional logic: a.out.h, kvm.h and kvm_para.h. For all three of them, change the logic to be something like: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),) which finds the header in only the two places it should be found, and doesn't get incorrectly triggered by the installation of asm-generic's version.

| * c6x: remove c6x signal.hMark Salter2012-10-042-17/+1Star
| | | | | | | | | | | | | | | | | | | | | | The c6x signal.h includes the asm-generic version and provides a couple of extern declarations. David Howells pointed out that the externs needed to be protected by ifdef __KERNEL__. As it turns out, the externs aren't really needed since the functions are only called from asm code. So this patch gets rid of the c6x signal.h and uses just the asm-generic version. Signed-off-by: Mark Salter <msalter@redhat.com>

* | UAPI: Fix the guards on various asm/unistd.h filesDavid Howells2012-10-049-40/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | asm-generic/unistd.h and a number of asm/unistd.h files have been given reinclusion guards that allow the guard to be overridden if __SYSCALL is defined. Unfortunately, these files define __SYSCALL and don't undefine it when they've finished with it, thus rendering the guard ineffective. The reason for this override is to allow the file to be #included multiple times with different settings on __SYSCALL for purposes like generating syscall tables. The following guards are problematic: arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL) arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL) arch/c6x/include/asm/unistd.h:#if !defined(_ASM_C6X_UNISTD_H) || defined(__SYSCALL) arch/hexagon/include/asm/unistd.h:#if !defined(_ASM_HEXAGON_UNISTD_H) || defined(__SYSCALL) arch/openrisc/include/asm/unistd.h:#if !defined(__ASM_OPENRISC_UNISTD_H) || defined(__SYSCALL) arch/score/include/asm/unistd.h:#if !defined(_ASM_SCORE_UNISTD_H) || defined(__SYSCALL) arch/tile/include/asm/unistd.h:#if !defined(_ASM_TILE_UNISTD_H) || defined(__SYSCALL) arch/unicore32/include/asm/unistd.h:#if !defined(__UNICORE_UNISTD_H__) || defined(__SYSCALL) include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL) On the assumption that the guards' ineffectiveness has passed unnoticed, just remove these guards entirely.

Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, only 2 control modes are available: - NONE: The fan is never touched (default) - MANUAL: The fan is set to the user-defined fan speed (pwm1) This patch introduces a distinction between ptherm internal fan management and external fan management. The latter is bound to respect the fan mode while the first can still select the speed it wants unless the NONE mode is selected. This is important for automatic fan management.
