Max Filippov 6ec7026ac0 xtensa: use context structure for debug exceptions ... With implementation of data breakpoints debug exceptions raised when PS.EXCM is set need to be handled, e.g. window overflow code can write to watched userspace address. Currently debug exception handler uses EXCSAVE and DEPC SRs to save temporary registers, but DEPC may not be available when PS.EXCM is set and more space will be needed to save additional state. Reorganize debug context: create per-CPU structure debug_table instance and store its address in the EXCSAVE<debug level> instead of debug_exception function address. Expand this structure when more save space is needed. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>		2016-03-11 08:53:32 +00:00
