2009-07-24Thumb-2: Implement the unified arch/arm/mm supportCatalin Marinas1-5/+15
This patch adds the ARM/Thumb-2 unified support to the arch/arm/mm/* files. Signed-off-by: Catalin Marinas <[email protected]>
2009-06-19[ARM] 5540/1: 32-bit Thumb-2 {ld,st}{m,rd} alignment fault fixup supportGeorge G. Davis1-20/+119
From: Min Zhang <[email protected]> Add alignment fault fixup support for 32-bit Thumb-2 LDM, LDRD, POP, PUSH, STM and STRD instructions. Alignment fault fixup support for the remaining 32-bit Thumb-2 load/store instruction cases is not included since ARMv6 and later processors include hardware support for loads and stores of unaligned words and halfwords.

2008-12-07[ARM] Fix alignment fault handling for ARMv6 and later CPUsRussell King1-3/+23
On ARMv6 and later CPUs, it is possible for userspace processes to get stuck on a misaligned load or store due to the "ignore fault" setting; unlike previous CPUs, retrying the instruction without the 'A' bit set does not always cause the load to succeed. We have no real option but to default to fixing up alignment faults on these CPUs, and having the CPU fix up those misaligned accesses which it can.

2007-10-19Use helpers to obtain task pid in printks (arch code)Alexey Dobriyan1-1/+1
One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files. It took some time to cross-compile it, but hopefully these are all the printks in arch code.

Fix various bits of obviously-busted code which we're not happening to compile, due to ifdefs.

2007-04-21[ARM] Remove needless linux/ptrace.h includesRussell King1-1/+0
Lots of places in arch/arm were needlessly including linux/ptrace.h, resumably because we used to pass a struct pt_regs to interrupt handlers. Now that we don't, all these ptrace.h includes are redundant. Signed-off-by: Russell King <[email protected]>
2006-09-27[ARM] do_bad_area() always takes current and current->active_mmRussell King1-1/+1
Since do_bad_area() always takes the currently active task and (supposed to) take the currently active MM, there's no point passing them to this function. Instead, obtain references to them inside do_bad_area(). Signed-off-by: Russell King <[email protected]>

2005-08-31[ARM] 2867/2: unaligned ldrd/strd fixupsSteve Longerbeam1-14/+56
Patch from Steve Longerbeam Adds an implementation of unaligned LDRD and STRD fixups. Also fixes a bug where do_alignment() would misinterpret and fixup an unaligned LDRD/STRD as LDRH/STRH, causing memory corruption. This is the same as Patch #2867/1, but with minor whitespace and comments changes, plus a check for arch-level >= v5TE before printing ai_dword count in proc_alignment_read().

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+756
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!
