2013-12-21efi: Export more EFI table variables to sysfsDave Young
Export fw_vendor, runtime and config table physical addresses to /sys/firmware/efi/{fw_vendor,runtime,config_table} because kexec kernels need them. From EFI spec these 3 variables will be updated to virtual address after entering virtual mode. But kernel startup code will need the physical address.

2013-12-21x86/efi: Add a wrapper function efi_map_region_fixed()Dave Young
Kexec kernel will use saved runtime virtual mapping, so add a new function efi_map_region_fixed() for directly mapping a md to md->virt. The md is passed in from 1st kernel, the virtual addr is saved in md->virt_addr.

2013-12-20b44: use fixed PHY device if we do not find anyHauke Mehrtens
The ADM6996L switch and some Broadcom switches with two MII interfaces like the BCM5325F connected to two MACs on the SoC, used on some routers do not return a valid value when reading the PHY id register and Linux thinks there is no PHY at all, but that is wrong.

For MCT block compatible with "samsung,exynos4412-mct", that uses PPI interrupts for local timers, only one local interrupt needs to be specified, since it is a per-processor interrupt.

The device tree sent upstream for exynos5250-snow encoded the search key as CAPSLK. However in all ChromeOS kernels it is L_META. One can certainly have long debates about which it ought to be, but I'm proposing setting it to L_META because: * That's how _all_ ChromeOS kernels do it and will do it. * There is no L_META key on the board, so it's nice to have. * For those people who really want it to be caps lock, they can use xmodmap or somesuch.

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen bugfixes from Konrad Rzeszutek Wilk: - Fix balloon driver for auto-translate guests (PVHVM, ARM) to not use scratch pages. - Fix block API header for ARM32 and ARM64 to have proper layout - On ARM when mapping guests, stick on PTE_SPECIAL - When using SWIOTLB under ARM, don't call swiotlb functions twice - When unmapping guests memory and if we fail, don't return pages which failed to be unmapped. - Grant driver was using the wrong address on ARM. * tag 'stable/for-linus-3.13-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/balloon: Seperate the auto-translate logic properly (v2) xen/block: Correctly define structures in public headers on ARM32 and ARM64 arm: xen: foreign mapping PTEs are special. xen/arm64: do not call the swiotlb functions twice xen: privcmd: do not return pages which we have failed to unmap XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn
2013-12-20ARM: versatile: enable LEDs by defaultLinus Walleij
This adds the LEDs and triggers used by the Versatile boards to the default configuration. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-12-20ARM: versatile: build using EABILinus Walleij
This should work just fine on this purely v5 platform, so let's config it for EABI by default. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-12-20ARM: versatile: enable GPIOLIB and PL061 by defaultLinus Walleij
Select the GPIOLIB and PL061 in the Versatile defconfig, as this is present on all boards, and so we get compile and test coverage for this. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-12-20ARM: versatile: update defconfigLinus Walleij
This updates the Versatile defconfig to the thing saved by savedefconfig so we don't get confusing diffs when trying to modify other options. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-12-20ARM: versatile: move GPIO2 and GPIO3 to coreLinus Walleij
Move GPIO2 and GPIO3 to be registered from the core as this is certainly available on Versatile AB as well, not just the PB. GPIO2 is used for reading board status and GPIO3 is unused, but it does not hurt to register it anyway. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-12-20ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij
This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

2013-12-20ARM: s3c24xx: get rid of custom <mach/gpio.h>Linus Walleij
This isolates the custom S3C24xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x24xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff. The biggest this can ever be for the S3C24XX is CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512 is the absolute roof value on this platform. So we set the size of ARCH_NR_GPIO to this and the GPIOs array will fit any S3C24XX platform, as per pattern from other archs. ChangeLog v2->v3: - Move the movement of the S3C64XX gpio.h file out of this patch and into the follow-up patch where it belongs. ChangeLog v1->v2: - Added an #ifdef ARCH_S3C24XX around the header inclusion in drivers/gpio/gpio-samsung.c as we would otherwise have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.
