2013-01-31arm: arch_timer: move core to drivers/clocksourceMark Rutland8-386/+476
The core functionality of the arch_timer driver is not directly tied to anything under arch/arm, and can be split out. This patch factors out the core of the arch_timer driver, so it can be shared with other architectures. A couple of functions are added so that architecture-specific code can interact with the driver without needing to touch its internals. The ARM_ARCH_TIMER config variable is moved out to drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with HAVE_ARM_ARCH_TIMER, which selects it.

2013-01-31arm: arch_timer: add arch_counter_set_user_accessMark Rutland2-0/+14
Several bits in CNTKCTL reset to 0, including PL0VTEN. For architectures using the generic timer which wish to have a fast gettimeofday vDSO implementation, these bits must be set to 1 by the kernel. For architectures without a vDSO, it's best to leave the bits set to 0 for now to ensure that if and when support is added, it's implemented sanely architecture wide. As the bootloader might set PL0VTEN to a value that doesn't correspond to that which the kernel prefers, we must explicitly set it to the architecture port's preferred value. This patch adds arch_counter_set_user_access, which sets the PL0 access permissions to that required by the architecture. For arch/arm, this currently means disabling all userspace access.

2013-01-31arm: arch_timer: divorce from local_timer apiMark Rutland1-23/+29
Currently, the arch_timer driver is tied to the arm port, as it relies on code in arch/arm/smp.c to setup and teardown timers as cores are hotplugged on and off. The timer is registered through an arm-specific registration mechanism, preventing sharing the driver with the arm64 port. This patch moves the driver to using a cpu notifier instead, making it easier to port.

2013-01-31arm: arch_timer: add isbs to register accessorsMark Rutland1-0/+4
Without the isbs in arch_timer_get_cnt{p,v}ct the cpu may speculate reads and return stale values. This could be bad for code sensitive to changes in expected deltas between calls (e.g. the delay loop). Without isbs in arch_timer_reg_write the processor may reorder instructions around enabling/disabling of the timer or writing the compare value, which we probably don't want. This patch adds isbs to prevent those issues. Signed-off-by: Mark Rutland <mark.rutland@arm.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com>
2013-01-31arm: arch_timer: factor out register accessorsMark Rutland2-92/+94
Currently the arch_timer register accessors are thrown together with the main driver, preventing us from porting the driver to other architectures. This patch moves the register accessors into a header file, as with the arm64 version. Constants required by the accessors are also moved.

2013-01-31arm: arch_timer: split cntfrq accessorMark Rutland1-7/+9
The CNTFRQ register is not duplicated for physical and virtual timers, and accessing it as if it were is confusing. Instead, use a separate accessor which doesn't take the access type as a parameter.

2013-01-31arm: arch_timer: standardise counter readingMark Rutland1-36/+22
We're currently inconsistent with respect to our accesses to the physical and virtual counters, mixing and matching the two. This patch introduces and uses a function pointer for accessing the correct counter based on whether we're using physical or virtual interrupts. All current accesses to the counter accessors are redirected through it. When the driver is moved out to drivers/clocksource, there's the possibility that code called before the timer code is initialised will attempt to call arch_timer_read_counter (e.g. sched_clock for AArch64). To avoid having to have to check whether the timer has been initialised either in arch_timer_read_counter or one of it's callers, a default implementation is assigned that simply returns 0.

2013-01-31arm: arch_timer: use u64/u32 for register dataMark Rutland1-19/+11
To ensure the correct size of types, use u64 for the return value of arch_timer_get_cnt{p,v}ct, and u32 for arch_timer_rate, matching the size of the registers these values are taken from. While we're changing them anyway, simplify the implementation of arch_timer_get_cnt{p,v}ct.

With commit 384a290 (ARM: gic: use a private mapping for CPU target interfaces), wake-up IPIs now go to all cores as the gic cpu interface numbering may not follow core numbering. This broke secondary boot on highbank since the boot address was already set for all secondary cores, this caused all cores to boot before the kernel was ready. Fix this by moving the setting of the jump address to highbank_boot_secondary instead of highbank_smp_prepare_cpus and highbank_cpu_die. Also, clear the address when we boot. This prevents cores from booting before they are actually triggered and is also necessary to get suspend/resume to work.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Summary: - change exynos file license . Most of exynos files had been copied from some randome file and not updated correctly(wrong company name used). This was our mistakes so chagnes it correctly. For this, I'm not sure that this patch should go to -fix or -next. So please give me any comment if there is any problem. - consider buffer allocation without iommu . Without iommu, dma_alloc_attrs function allocates some memory region and returns cpu address so this patch makes the cpu address to be set to buf->kvaddr correctly - cleanups to ipp relevant codes. - use common finish page flip function . to avoid the duplication of same code, use exynos_drm_crtc_finish_pageflip function commonly instead of each one. - fix fimd resume issue. . when fimd was turned off by suspend, there was one issue that the fimd wasn't turned on by resume so fix it chaing resume condition. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (25 commits) drm/exynos: move finish page flip to a common place drm/exynos: fimd: modify condition in fimd resume drm/exynos: Use devm_clk_get in exynos_drm_gsc.c drm/exynos: Remove redundant NULL check in exynos_drm_gsc.c drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.c drm/exynos: Use devm_clk_get in exynos_drm_rotator.c drm/exynos: Remove redundant NULL check in exynos_drm_rotator.c drm/exynos: Remove unnecessary devm_* freeing APIs in exynos_drm_rotator.c drm/exynos: Use devm_clk_get in exynos_drm_fimc.c drm/exynos: Remove redundant NULL check drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c drm/exynos: Use devm_kzalloc in exynos_drm_ipp.c drm/exynos: fix gem buffer allocation type checking drm/exynos: remove needless parenthesis. drm/exynos: fix incorrect interrupt induced by m2m operation. drm/exynos: remove color bar pattern operation. drm/exynos: correct some comments to abbreviation. drm/exynos: fix build warning. drm/exynos: consider both case of vflip and hflip. drm/exynos: remove needless error handling to property. ...

2013-01-08ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs arrayPantelis Antoniou1-1/+1
The IRQ array must be terminated by -1 and not by -1+OMAP_INTC_START This led to having a resource list of 100s of IRQs. Looks like this was caused by commit a2cfc509 (ARM: OMAP3+: hwmod: Add AM33XX HWMOD data) that probably had some search and replace updates done for the patch for sparse irq support.

2013-01-07sctp: fix Kconfig bug in default cookie hmac selectionAlex Elder1-1/+1
Commit 0d0863b02002 ("sctp: Change defaults on cookie hmac selection") added a "choice" to the sctp Kconfig file. It introduced a bug which led to an infinite loop when while running "make oldconfig". The problem is that the wrong symbol was defined as the default value for the choice. Using the correct value gets rid of the infinite loop. Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present in the generated config file.

2013-01-07EDAC: Fix EDAC Kconfig menuBorislav Petkov1-5/+3
After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering the "Device Drivers" toplevel menu in menuconfig, the suboptions behind EDAC appeared merged with the rest of the device drivers types. This was because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig bool which was defined after the menu definition. When pushing EDAC_SUPPORT up, before the menu definition, the variable is defined earlier and the above menuconfig artifact doesn't happen. Drop a useless menuconfig comment while at it.

2013-01-07EDAC: Fix kernel panic on module unloadingKonstantin Khlebnikov1-2/+1
This patch fixes use-after-free and double-free bugs in edac_mc_sysfs_exit(). mci_pdev has single reference and put_device() calls mc_attr_release() which calls kfree(). The following device_del() works with already released memory. An another kfree() in edac_mc_sysfs_exit() releses the same memory again. Great.

The mute LED is in this case connected to the Mic1 VREF. The machine also exposes the following string in BIOS: "HP_Mute_LED_0_A", so if more machines are coming, it probably makes sense to try to do something more generic, like for the IDT codec.
