* [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_userDan Williams2007-02-171-0/+6
| | | | | | | | | | | | | | | get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.

* [ARM] Remove "translated" io macrosRussell King2006-11-301-26/+5
| | | | | | | | The "translated" io macros were never really used. Remove them. Preserve the L7200 inb() and friends by defining the __io() macro, so that the generic versions can be used instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] L7200: Remove deprecated __io_pci and __arch_(get|put)*Russell King2006-11-301-27/+0
| | | | | | | These functions have been deprecated for quite some time, and in fact are no longer used. They just add to clutter. Remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* Initial blind fixup for arm for irq changesLinus Torvalds2006-10-061-1/+2
| | | | | | | Untested, but this should fix up the bulk of the totally mechanical issues, and should make the actual detail fixing easier. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

* [ARM] 3759/2: Remove uses of %?Daniel Jacobowitz2006-09-201-4/+4
| | | | | | | | | | | | | | | | | | | | | | | Patch from Daniel Jacobowitz The ARM kernel has several uses of asm("foo%?"). %? is a GCC internal modifier used to output conditional execution predicates. However, no version of GCC supports conditionalizing asm statements. GCC 4.2 will correctly expand %? to the empty string in user asms. Earlier versions may reuse the condition from the previous instruction. In 'if (foo) asm ("bar%?");' this is somewhat likely to be right... but not reliable. So, the only safe thing to do is to remove the uses of %?. I believe the tlbflush.h occurances were supposed to be removed before, based on the comment about %? not working at the top of that file. Old versions of GCC could omit branches around user asms if the asm didn't mark the condition codes as clobbered. This problem hasn't been seen on any recent (3.x or 4.x) GCC, but it could theoretically happen. So, where %? was removed a cc clobber was added.

* [ARM] Move FLUSH_BASE macros to asm/arch/memory.hRussell King2006-04-072-3/+6
| | | | | | | | | FLUSH_BASE must be visible to arch/arm/mm/init.c in order for the memory region to be setup. Move these definitions from asm-arm/arch-*/hardware.h into asm-arm/arch-*/memory.h where mm stuff can see them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Fix decompressor serial IO to give CRLF not LFCRRussell King2006-03-281-10/+5
| | | | | | | | | As per the corresponding change to the serial drivers, arrange for ARM decompressors to give CRLF. Move the common putstr code into misc.c such that machines only need to supply "putc" and "flush" functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Move HZ definition into KconfigRussell King2006-03-211-19/+0

* [ARM] Remove definition of MAX_DMA_CHANNELS to zeroRussell King2006-01-041-1/+0
| | | | | | | | | Since we now only build arch/arm/kernel/dma.c on machine types which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS to 0 to indicate this - this definition becomes superfluous. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Cleanup ARM includesRussell King2006-01-031-0/+2
| | | | | | | | | | | | | | | | arch/arm/kernel/entry-armv.S has contained a comment suggesting that asm/hardware.h and asm/arch/irqs.h should be moved into the asm/arch/entry-macro.S include. So move the includes to these two files as required. Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h includes which use those facilities, and remove asm/io.h from kernel/process.c. Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm and arch/arm/mach-footbridge. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | Patch from Nicolas Pitre This patch allows for assorted type of cleanups by letting assembly code use the same set of defines for constant values and avoid duplicated definitions that might not always be in sync, or that might simply be confusing due to the different names for the same thing.

* Linux-2.6.12-rc2Linus Torvalds2005-04-1622-0/+1175
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
