2015-11-02xtensa: fixes for configs without loop optionMax Filippov
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. Cc: <stable@vger.kernel.org> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2008-11-06xtensa: move headers files to arch/xtensa/includeChris Zankel
Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.

2006-12-10[PATCH] xtensa: remove extra header filesChris Zankel
The Xtensa port contained many header files that were never needed. This rather lengthy patch removes all those files. Unfortunately, there were many dependencies that needed to be updated, so this patch touches quite a few source files.

2006-10-03Attack of "the the"s in archMatt LaPlante
The patch below corrects multiple occurances of "the the" typos across several files, both in source comments and KConfig files. There is no actual code changed, only text. Note this only affects the /arch directory, and I believe I could find many more elsewhere. :) Signed-off-by: Adrian Bunk <bunk@stusta.de>
