Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO expanders. It will be populated by later patches. This won't be the only place to hold such gpio_chip code. Many external chips add a few GPIOs as secondary functionality (such as MFD drivers) and platform code frequently needs to closely integrate GPIO and IRQ support. This is placed *early* in the build/link sequence since it's common for other drivers to depend on GPIOs to do their work, so they must be initialized early in the device_initcall() sequence.

This is the new timerfd API as it is implemented by the following patch: int timerfd_create(int clockid, int flags); int timerfd_settime(int ufd, int flags, const struct itimerspec *utmr, struct itimerspec *otmr); int timerfd_gettime(int ufd, struct itimerspec *otmr); The timerfd_create() API creates an un-programmed timerfd fd. The "clockid" parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME. The timerfd_settime() API give new settings by the timerfd fd, by optionally retrieving the previous expiration time (in case the "otmr" parameter is not NULL). The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit is set in the "flags" parameter. Otherwise it's a relative time. The timerfd_gettime() API returns the next expiration time of the timer, or {0, 0} if the timerfd has not been set yet. Like the previous timerfd API implementation, read(2) and poll(2) are supported (with the same interface). Here's a simple test program I used to exercise the new timerfd APIs: http://www.xmailserver.org/timerfd-test2.c [akpm@linux-foundation.org: coding-style cleanups] [akpm@linux-foundation.org: fix ia64 build] [akpm@linux-foundation.org: fix m68k build] [akpm@linux-foundation.org: fix mips build] [akpm@linux-foundation.org: fix alpha, arm, blackfin, cris, m68k, s390, sparc and sparc64 builds] [heiko.carstens@de.ibm.com: fix s390] [akpm@linux-foundation.org: fix powerpc build] [akpm@linux-foundation.org: fix sparc64 more] Signed-off-by: NDavide Libenzi <davidel@xmailserver.org> Cc: Michael Kerrisk <mtk-manpages@gmx.net> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Davide Libenzi <davidel@xmailserver.org> Cc: Michael Kerrisk <mtk-manpages@gmx.net> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This patch moves the platform specific definitions from platform.h into the board-eb.h file. It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files.

This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer.

Currently, the atags used by kexec are fixed to the ones originally used to boot the kernel. This is less than ideal as changing the commandline, initrd and other options would be a useful feature. This patch exports the atags used for the current kernel to userspace through an "atags" file in procfs. The presence of the file is controlled by its own Kconfig option and cleans up several ifdef blocks into a separate file. The tags for the new kernel are assumed to be at a fixed location before the kernel image itself. The location of the tags used to boot the original kernel is unimportant and no longer saved.

Currently early kernel messages, i.e., those from uncompression, go to the debugging UART. And if it is enabled in the platform configuration, but not initialized by the bootloader, the machine hangs, waiting for UART status change. Besides, having those messages on another UART - typically the console UART - may be preferrable. This patch allows selecting the UART in kernel configuration.

On the at91sam9263, IRQs for GPIO banks C and D don't currently work. This is because banks C, D, and E share one clock and toplevel IRQ, but the AT91 code setting up and handling GPIO IRQs expects no sharing. This patch: - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are shared like on sam9263 chips, by setting up a list of those banks and making the IRQ dispatching logic scan that list. - Precomputes the address of each bank's registers, saving it with other per-bank data so that it no longer needs to be constantly recomputed during IRQs and other GPIO operations. That shrinks hot-path code, while helping the GPIO bank irq updates. - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just means "use the default", which is "both edges" here).
