xtensa: fixes for configs without loop option

2016-02-19T22:28:28Z

commit 5029615e25dc5040beb065f36743c127a8e51497 upstream. Build-time fixes: - make lbeg/lend/lcount save/restore conditional on kernel entry; - don't clear lcount in platform_restart functions unconditionally. Run-time fixes: - use correct end of range register in __endla paired with __loopt, not the unused temporary register. This fixes .bss zero-initialization. Update comments in asmmacro.h; - don't clobber a10 in the usercopy that leads to access to unmapped memory. Signed-off-by: Max Filippov Signed-off-by: Greg Kroah-Hartman
