* [ARM] 4170/1: S3C2410: don't save and restore cp register 15Matt Reimer2007-02-12
| | | | | | | | | | Don't save and restore cp register 15 since it is only a test register on S3C2410. This is probably a leftover from the PXA sleep.S from which this was derived. Supersedes patch 4167. Signed-off-by: Matt Reimer <mreimer@vpop.net> Acked-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4169/1: S3C2410: align to a cache lineMatt Reimer2007-02-12
| | | | | | | | | | | | Align the code to the start of the next cache line, rather than the start of the next 256-byte page. (On i386 and ARM, the ".align" assembler directive takes its first argument as the number of low-order bits that must be zero, not the number of words comprising a cache line.) Supercedes patch 4166.

* [ARM] Move processor_modes[] to .../process.cRussell King2007-02-06
| | | | | | | | | | | | | | bad_mode() currently prints the mode which caused the exception, and then causes an oops dump to be printed which again displays this information (since the CPSR in the struct pt_regs is correct.) This leads to processor_modes[] being shared between traps.c and process.c with a local declaration of it. We can clean this up by moving processor_modes[] to process.c and removing the duplication, resulting in processor_modes[] becoming static. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [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] 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>

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).

* [ARM] Resolve fuse and direct-IO failures due to missing cache flushesRussell King2007-01-08
| | | | | | | | | | | | | | | fuse does not work on ARM due to cache incoherency issues - fuse wants to use get_user_pages() to copy data from the current process into kernel space. However, since this accesses userspace via the kernel mapping, the kernel mapping can be out of date wrt data written to userspace. This can lead to unpredictable behaviour (in the case of fuse) or data corruption for direct-IO. This resolves debian bug #402876 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Fix kernel-mode undefined instruction abortsRussell King2007-01-06
| | | | | | | | | If the kernel attempts to execute a CP1 or CP2 instruction and it aborts, and a FP emulator is not loaded, we try to return as if to a user context, instead of the proper kernel context.
