* ARM: entry: data abort: ensure r5 is preserved by abort functionsRussell King2011-07-021-26/+22

* ARM: entry: data abort: use r2 as base of pt_regs rather than stackRussell King2011-07-021-12/+12
| | | | | | | | Now that we pass r2 into these helper functions as the pointer to pt_regs, use r2 as the base of the registers on the stack rather than using the stack pointer directly. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: entry: data abort: tail-call the main data abort handlerRussell King2011-07-021-22/+21
| | | | | | | | Tail-call the main C data abort handler code from the per-CPU helper code. Update the comments in the code wrt the new calling and return register state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: entry: data abort: avoid using r2 in abort helpersRussell King2011-07-021-17/+17
| | | | | | | This allows us to pass the pt_regs pointer in to these functions ready for tail-calling the abort handler. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: entry: data abort: arrange for CPU abort helpers to take pc/psr in r4/r5Russell King2011-07-021-6/+6
| | | | | | | Re-jig the CPU abort helpers to take the PC/PSR in r4/r5 rather than r2/r3. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] nommu: abort handler fixup for !CPU_CP15_MMU cores.Hyok S. Choi2006-09-281-1/+6
| | | | | | | | | | There is no FSR/FAR register on no-CP15 or MPU cores. This patch adds a dummy abort handler which returns zero for the base restored Data Abort model !CPU_CP15_MMU cores. The abort-lv4t.S is still used with the fix-up for the base updated Data Abort model cores. Signed-off-by: Hyok S.

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!
