2014-05-09arm64: Provide read/write fault information in compat signal handlersCatalin Marinas
For AArch32, bit 11 (WnR) of the FSR/ESR register is set when the fault was caused by a write access and applications like Qemu rely on such information being provided in sigcontext. This patch introduces the ESR_EL1 tracking for the arm64 kernel faults and sets bit 11 accordingly in compat sigcontext. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2014-02-05arm64: fix typo: s/SERRROR/SERROR/Mark Rutland
Somehow SERROR has acquired an additional 'R' in a couple of headers. This patch removes them before they spread further. As neither instance is in use yet, no other sites need to be fixed up.

2013-04-17arm64: add explicit symbols to ESR_EL1 decodingMarc Zyngier
The ESR_EL1 decoding process is a bit cryptic, and KVM has also a need for the same constants. Add a new esr.h file containing the appropriate exception classes constants, and change entry.S to use it. Fix a small bug in the EL1 breakpoint check while we're at it.
