The lock annotation macros __acquires, __releases, __acquire, and __release all currently throw away the lock expression passed as an argument. Now that sparse can parse __context__ and __attribute__((context)) with a context expression, pass the lock expression down to sparse as the context expression. This requires a version of sparse from GIT commit 37475a6c1c3e66219e68d912d5eb833f4098fd72 or later. Signed-off-by:

If the driver has interrupts available to it, there is really no reason to have a kernel daemon push the IPMI state machine. Note that I have experienced machines where the interrupts do not work correctly. This was a long time ago and hopefully things are better now. If some machines still have broken interrupts, a blacklist will need to be added. Signed-off-by:

This syncs the omap_cf driver with the one from the linux-omap tree. Changes include fixing build warnings (section mismatch, unused return value) and coping with various pcmcia core changes related to managing i/o memory and irq resources. Signed-off-by:

This lets the at91rm9200 RTC alarm be a system wakeup irq, according to the setting of /sys/devices/platform/at91_rtc/power/wakeup. User code can set the alarm, put the system into a low power mode, and then rely on it waking up no later than the specified moment. Signed-off-by:

The rtc_is_valid_tm() routine needs to treat some of the fields it checks as unsigned, to prevent wrongly accepting invalid rtc_time structs; this is the same approach used elsewhere in the RTC code for such tests. Conversely, rtc_proc_show() is missing one invalid-day-of-month test that rtc_is_valid_tm() makes: there is no day zero. Signed-off-by:

This makes RTC core components use "subsys_init" instead of "module_init", as appropriate for subsystem infrastructure. This is mostly useful for statically linking drivers in other parts of the tree that may provide an RTC interface as a secondary functionality (e.g. part of a multifunction chip); they won't need to worry so much about drivers/Makefile link order.

Small updates to make the RTC class Kconfig text be more informative. This should help folk used to the drivers/char/rtc.c support, or a single RTC, be slightly less surprised by the differences. Also, adds a new RTC_DEBUG option to predefine DEBUG in the framework and its drivers, while debugging. That's getting to be a standard idiom, and it's pretty useful. Signed-off-by:

The century bit PCF8563_MO_C in the month register is misinterpreted. It is set to 1 for the 20th century and 0 for 21th, and the driver is expecting the opposite behavior. Acked-by:

This is one of a series of patches I plan to gradually trickle into the tree which eliminates almost all remaining use of pci_find_* and lets me build a pci_find_* free kernel for all but some obscure ISDN and SCSI drivers. This is important as all pci_find_* users are not hotplug safe - even if they are not the device being plugged. Signed-off-by:

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can boot one single binary on pseries and G5 boards. pmac has no legacy io, probing for PC style legacy hardware (or accessing the legacy io area regulary) may lead to a hard crash: * add check for parport_pc, exit on pmac. 32bit chrp has no ->check_legacy_ioport, the probe is always called. 64bit chrp has check_legacy_ioport, check for a "parallel" node * add check for isapnp, only PReP boards may have real ISA slots. 32bit PReP will have no ->check_legacy_ioport, the probe is always called. * update code in i8042_platform_init. Run ->check_legacy_ioport first, always call request_region. No functional change. Remove whitespace before i8042_reset init. Signed-off-by:

Powerpc already has a directed yield for CONFIG_PREEMPT="n". To make it work with CONFIG_PREEMPT="y" as well the _raw_{spin,read,write}_relax primitives need to be defined to call __spin_yield() for spinlocks and __rw_yield() for rw-locks. Acked-by:Paul Mackerras <paulus@samba.org> Signed-off-by:

On systems running with virtual cpus there is optimization potential in regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock is known to a cpu that wants to acquire the same lock it is beneficial to yield the timeslice of the virtual cpu in favour of the cpu that has the lock (directed yield). With CONFIG_PREEMPT="n" this can be implemented by the architecture without common code changes. Powerpc already does this. With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock, _raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock could not be taken cpu_relax is called. A directed yield is not possible because cpu_relax doesn't know anything about the lock. To be able to yield the lock in favour of the current lock holder variants of cpu_relax for spinlocks and rw-locks are needed. The new _raw_spin_relax, _raw_read_relax and _raw_write_relax primitives differ from cpu_relax insofar that they have an argument: a pointer to the lock structure. Signed-off-by:

I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger. Signed-off-by:
