* ARM: Fix csum_partial_copy_from_user()Russell King2010-07-261-1/+1
| | | | | | | | | | | Using the parent functions frame pointer to access our arguments is completely wrong, whether or not we're building with frame pointers or not. What we should be using is the stack pointer to get at the word above the registers we stacked ourselves.

* ARM: fix build error in arch/arm/kernel/process.cRussell King2010-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | | /tmp/ccJ3ssZW.s: Assembler messages: /tmp/ccJ3ssZW.s:1952: Error: can't resolve `.text' {.text section} - `.LFB1077' This is caused because: .section .data .section .text .section .text .previous does not return us to the .text section, but the .data section; this makes use of .previous dangerous if the ordering of previous sections is not known. Fix up the other users of .previous; .pushsection and .popsection are a safer pairing to use than .section and .previous. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* Thumb-2: Implement the unified arch/arm/lib functionsCatalin Marinas2009-07-241-35/+13Star
| | | | | | | | | | This patch adds the ARM/Thumb-2 unified support for the arch/arm/lib/* files. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* [ARM] 5231/1: Do not save the frame pointer in the csum_partial_copy_* functionsCatalin Marinas2008-09-011-4/+2Star
| | | | | | | | | Since the other assembly functions do not seem to save the frame pointer onto the stack, this patch changes the csum_partial_copy_* functions to behave in the same way.

* [ARM] 5227/1: Add the ENDPROC declarations to the .S filesCatalin Marinas2008-09-011-0/+1
| | | | | | | | | This declaration specifies the "function" type and size for various assembly functions, mainly needed for generating the correct branch instructions in Thumb-2. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 3256/1: Make the function-returning ldm's use sp as the base registerCatalin Marinas2006-01-121-3/+5
| | | | | | | | | | | | | | | | | | Patch from Catalin Marinas If the low interrupt latency mode is enabled for the CPU (from ARMv6 onwards), the ldm/stm instructions are no longer atomic. An ldm instruction restoring the sp and pc registers can be interrupted immediately after sp was updated but before the pc. If this happens, the CPU restores the base register to the value before the ldm instruction but if the base register is not sp, the interrupt routine will corrupt the stack and the restarted ldm instruction will load garbage. Note that future ARM cores might always run in the low interrupt latency mode. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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!
