* [ARM] 4112/1: Only ioremap to supersections if DOMAIN_IO is zeroCatalin Marinas2007-01-25
| | | | | | | | | Supersections do not have a field for the domain and it is always 0. This patch prevents the creation of supersections during ioremap when DOMAIN_IO is not zero (i.e. !defined(CONFIG_IO_36)).

* [ARM] 4102/1: Allow for PHYS_OFFSET on any valid 2MiB addressLinus Walleij2007-01-24
| | | | | | | | | | | | | | | | | | This patchs allows the offset to the first page of physical memory to be on any 2MB boundary whereas the previous code could only handle psysical offset to any 16MB boundary (0xNN000000) or any 1MB boundary below 0x01000000 (e.g. 0x00N00000). The problem is a consequence of the orr one-byte syntax, so we fix this and we can place the first bank of memory at 0x28e00000. I have also included an explicit check that disallow compilation when PHYS_OFFSET is not on a 2MiB boundary. head.S would be the proper place to have this at since this is the first file that attempts to use PHYS_OFFSET during compile.

* [ARM] Fix AMBA serial drivers for non-first serial portsRussell King2007-01-24

* [ARM] 4096/1: S3C24XX: change return code form s3c2410_gpio_getcfg()Ben Dooks2007-01-24
| | | | | | | | | | | | | | | | The s3c2410_gpio_getcfg() currently returns a value which is dependant on the GPIO no passed in. Now we have more generic constants it is sensible to use those as return codes so that any function dealing with >1 GPIO does not need to do it's own number processing. Since this function is only currently used in pm.c, it is easy to fixup (and correct pm.c to use the generic constants) Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | GPIO bank A can only be output or a special function, and the regs-gpio.h header has mistakenly got this as input or output. The mistake is carried on into the gpio.c s3c2410_gpio_cfgpin() call which will set the wrong value if S3C2410_GPIO_OUTPUT is passed.

* [ARM] 4089/1: AT91: GPIO wake IRQ cleanupAndrew Victor2007-01-24
| | | | | | | | | | | | | | | Cleanup of at91 platform level gpio wake and suspend/resume logic. The GPIO core now delegates wakeups to the parent AIC by refcounting, and delegates clock management to the clock API. This makes these system modules more independent of each other, which is cleaner and will also help with the AT91SAM9263 (where some GPIO controllers share the same irq and clock).

| * [MIPS] SMTC: Instant IPI replay.Ralf Baechle2007-01-23
| | | | | | | | | | | | | | | | | | | | | | | | SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

And i dont even have oprofile enabled! All distro kernels have CONFIG_PROFILING enabled, so this scalability problem affects the majority of Linux users. The fix is to enhance blocking_notifier_call_chain() to only take the lock if there appears to be work on the call-chain. With this patch applied i get nicely saturated system, and much higher munmap performance, on SMP systems. And as a bonus this also fixes a similar scalability bottleneck in the thread-exit codepath: profile_task_exit() ...
