I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

* watchdog: pc87413_wdt: Cleanup pc87413 watchdog driver to useJonathan McDowell2011-07-221-46/+50
| | | | | | | | | | | | | | | | | | | | | | Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87 drivers to use request_muxed_region for accessing the SuperIO area on these chips, and the fact I have a GPIO driver for the pc8741x basically ready for submission, here is a patch to cleanup the pc87413 watchdog driver to use request_muxed_region for accessing the SuperIO area. It also pulls out the details about the SWC IO area on initial driver load, and properly does a request_region for that area - there's no requirement to touch the SuperIO area after doing the initial watchdog enable and IO base retrieval. While I have hardware with a pc87413 on it it is not wired in a way that allows the watchdog to reboot the machine, so I have not been able to fully test these changes - I have checked that the driver correctly initialises itself still and requests the SWC io region ok.

* watchdog: fix several MODULE_PARM_DESC stringsRandy Dunlap2010-05-251-3/+6
| | | | | | | | | | | | | | | | Fix MODULE_PARM_DESC() strings in several watchdog drivers. Some are simple as add a parenthesis. Others are problems from __stringify() being used on a variable name instead of a macro name, so the variable name is produced in the string instead of its build-time value. In these cases, create a macro for the value so that the module param description string is useful. Only pc87413_wdt has been built (due to toolchains).

* [WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck2008-08-061-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | This brings the watchdog drivers into line with coding style. This patch takes cares of the indentation as described in chapter 1. Main changes: * Re-structure the ioctl switch call for all drivers as follows: switch (cmd) { case WDIOC_GETSUPPORT: case WDIOC_GETSTATUS: case WDIOC_GETBOOTSTATUS: case WDIOC_GETTEMP: case WDIOC_SETOPTIONS: case WDIOC_KEEPALIVE: case WDIOC_SETTIMEOUT: case WDIOC_GETTIMEOUT: case WDIOC_GETTIMELEFT: default: } This to make the migration from the drivers to the uniform watchdog device driver easier in the future.
