* gpiolib: gpio_to_irq() hooksDavid Brownell2008-10-161-0/+18
| | | | | | | | | | | | | | Add a new gpiolib mechanism: gpio_chip instances can provide mappings between their (input) GPIOs and any associated IRQs. This makes it easier for platforms to support IRQs that are provided by board-specific external chips instead of as part of their core (such as SOC-integrated GPIOs). Also update the irq_to_gpio() description, saying to avoid it because it's not always supported.

* gpio: i2c expanders use subsys_initDavid Brownell2008-10-163-3/+12
| | | | | | | | | | | | | | | | | | | | Make the I2C external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked. SOC-integrated GPIOs are available starting very early -- early in arch_initcall() at latest, but often even before initcalls start to run -- so this improves consistency, so more subsystems can rely on GPIOs in their own subsys_initcall() code. (This isn't a theoretical problem. This is one of several patches needed to resolve oopsing observed when statically linking kernels on a DaVinci EVM. Its pcf857x GPIOs needed to be available well before some other drivers initialized.)

| | | | | | | | | | | | | | | | There is a small race and code ugliness in max7301: pins are reconfigured after the chip is registered.

| | | | | | | | | | | | | | | | | | | Add support for M41T65 Real Time Clock chip. The main differences I see between the M41T65 and M41T80 are that: 1) The M41T65 watchdog timer has three bits controlling resolution (versus two for the M41T80). 2) There is no register 0x13 for controlling square-wave output.

* rtc: file close() consistently disables repeating irqsDavid Brownell2008-10-165-47/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Make the rtc framework consistent about disabling 1/second update IRQs that may have been activated through the /dev interface, when that /dev file is closed. (It may have closed because of coredump, etc.) This was previously done only for emulated update IRQs ... now, do it always. Also comment the current policy: repeating IRQs (periodic, update) that userspace enabled will be cleanly disabled, but alarms are left alone. Such repeating IRQs are a constant and pointless system load. Update some RTC drivers to remove now-needless release() methods. Most such methods just enforce that policy. The others all seem to be buggy, and mistreat in-kernel clients of periodic or alarm IRQs.

* rtc: rtc-rs5c372: SMBus conversion/supportPaul Mundt2008-10-161-78/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | rtc-rs5c372 presently depends on I2C master mode transfers, despite the fact that these RTCs frequently find themselves on SMBus-only adapters. Given that the only capabilities that were checked were for I2C_FUNC_I2C, it's assumed that most of the adapters that are currently using this driver are fairly sane, and are able to handle SMBus emulation (though we adjust the default capabilities to check for I2C_FUNC_SMBUS_EMUL anyways, which is the vast majority of them. The adapters that don't have their own ->smbus_xfer() fall back on the ->master_xfer() through the emulated transfer). The special case is iop3xx, which has more than its fair share of hacks within this driver, it remains untested -- though also claims to support emulated SMBus accesses. The corner case there is rs5c_get_regs() which uses access mode #3 for transferring the register state, while we use mode #1 for SMBus.

* legacy rtc: remove needless/confusing HPET_RTC_IRQ optionDavid Brownell2008-10-162-10/+1
| | | | | | | | | | | | | | | | | | | | | | | HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more correct. (http://bugzilla.kernel.org/show_bug.cgi?id=11111) Note that when using the legacy RTC driver, platforms don't really do a dynamic switch between HPET and non-HPET modes based on whether HPET hardware actually exists ... only rtc-cmos (using the new RTC framework) currently switches that way. So this reflects bitrot in that legacy code, for x86/ia64: kernels with HPET support configured (e.g. for a clocksource) can't get IRQs from the legacy RTC driver unless they really have HPET hardware. (The obvious workaround is to not use the legacy RTC driver on those platforms when you configure HPET ... unless you know the target really has a HPET.)

| | | | | | | | | | | | | | | | | | | | | | | The I2O ioctls assume 32bits. In itself that is fine as they are old cards and nobody uses 64bit. However on LKML it was noted this assumption is also made for allocated memory and is unsafe on 64bit systems. Fixing this is a mess. It turns out there is tons of crap buried in a header file that does racy 32/64bit filtering on the masks. So we: - Verify all callers of the racy code can sleep (i2o_dma_[re]alloc) - Move the code into a new i2o/memory.c file - Remove the gfp_mask argument so nobody can try and misuse the function - Wrap a mutex around the problem area (a single mutex is easy to do and none of this is performance relevant) - Switch the remaining problem kmalloc holdout to use i2o_dma_alloc Cc: Markus Lidel <Markus.Lidel@shadowconnect.com> Cc: Vasily Averin <vvs@sw.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | proc_clear_tty() gets called with interrupts off (while holding the task list lock) from sys_setid. This means that it needs the _irqsave version of the locking primitives.

The notifier_del is called with a lock held, and in turns calls free_irq which then complains when manipulating procfs. This fixes it by moving the call to the notifier to outside of the locked section.
