2011-10-03clocksource: fixup ux500 build problemsLinus Walleij
Based on a patch from Arnd Bergmann this fixes up the build problem of assigning a non-existing global when the ux500 PRCMU timer is not linked in by passing its base address to the init function. We also add a missing <linux/errno.h> inclusion and staticize the dummy function. Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2011-10-01ARM: common/vic: use proper __iomem annotationsArnd Bergmann
In vic_init, we pass addr into readl, so it needs to be a pointer, not a u32 address. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: OC_ETM should not select ARM_AMBAArnd Bergmann
The CONFIG_ARM_AMBA symbol is selected by the platforms that support AMBA, and the other platforms (e.g. orion) might not be able to build that code at all when they do not support the clk API. Instead, make sure that OC_ETM is only built on platforms that do support the amba subsystem already. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pci: always export pcibios_bus_to_resourceArnd Bergmann
Some PCI drivers call pcibios_bus_to_resource directly, but it is only exported when CONFIG_HOTPLUG is set, because it was initially mean for pccard support. Moving the export out of the #ifdef lets us avoid these build errors: ERROR: "pcibios_bus_to_resource" [drivers/video/vt8623fb.ko] undefined! ERROR: "pcibios_bus_to_resource" [drivers/video/arkfb.ko] undefined! ERROR: "pcibios_bus_to_resource" [drivers/video/s3fb.ko] undefined! Signed-off-by: Arnd Bergmann <arnd@arndb.de>

These functions are used in some PCI drivers with big-endian MMIO space, and they are trivial to add here. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: limit CONFIG_HAVE_IDE to platforms that doArnd Bergmann
Support for IDE drivers should not be automatic, since most platforms cannot actually support any IDE low-level drivers. This partly reverts 2064c946e "ARM: always select HAVE_IDE" to set this symbol only when either a PC-style bus (PCI, ISA, PCMCIA) is enabled or a platform is used that is known to have an existing driver in drivers/ide. New platforms should not need this option and just use CONFIG_ATA with drivers/ata/. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pm: let platforms select cpu_suspend supportArnd Bergmann
Support for the cpu_suspend functions is only built-in when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4 and pxa always call cpu_suspend when CONFIG_PM is enabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: vfp: use -mfloat-abi=soft to build vfpArnd Bergmann
Distros are starting to ship with toolchains defaulting to hardfloat. Using such a compiler to build the kernel fails in the VFP directory with arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP Adding -mfloat-abi=soft to the gcc command line fixes this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: allow building alignment.c without PROC_FSArnd Bergmann
The two functions cpu_is_v6_unaligned and safe_usermode are only defined when CONFIG_PROC_FS is enabled, but are used outside of the #ifdef. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Dave Martin <dave.martin@linaro.org>
2011-10-01ARM: always use ARM_UNWIND for thumb2 kernelsArnd Bergmann
Thumb2 kernels cannot be built with frame pointers, but can use the ARM_UNWIND feature for unwinding instead. This makes sure that all features that rely on unwinding includeing CONFIG_LATENCYTOP and FAULT_INJECTION_STACKTRACE_FILTER do not enable frame pointers when the unwinder is already selected, and we always build with the unwinder when we want a thumb2 kernel, to make sure we do not get the frame pointers instead. A different option would be to redefine the CONFIG_FRAME_POINTERS option on ARM to mean builing with either frame pointers or the unwinder, and then select which one to use based on the CPU architecture or another user option. That would still allow building thumb2 kernels without the unwinder but would also be more confusing. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: SMP depends on MMUArnd Bergmann
The SMP implementation on ARM heavily depends on MMU-only code. As long as nobody is interested in fixing this, let's disable the SMP option when building for nommu. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: export rtc_lock for nvram driverArnd Bergmann
The rtc_lock is used by both the nvram and rtc drivers, so we need to export it if at least one of the two is built, not just for the rtc driver. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: 7113/1: mm: Align bank start to MAX_ORDER_NR_PAGESLinus Walleij
The VM subsystem assumes that there are valid memmap entries from the bank start aligned to MAX_ORDER_NR_PAGES. On the Ux500 we have a lot of mem=N arguments on the commandline triggering this bug several times over and causing kernel oops messages.

2011-09-30ARM: OMAP4: MMC: fix power and audio issue, decouple USBC1 from MMC1Bryan Buckley
Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for MMC1_PBIAS and associated extended-drain MMC1 I/O cell. This is in accordance with the control module programming guide. This fixes a bug where if trying to use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be affected by a changing SDMMC1_VDDS. Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever SDMMC1_VDDS ramps up/down or changes for cell protection purposes. MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore they can operate independently.
