2017-12-10xtensa: clean up functions in assembly codeMax Filippov
Use ENTRY and ENDPROC throughout arch/xtensa/lib assembly sources. Introduce asm/linkage.h and define xtensa-specific __ALIGN macro there. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2017-12-10xtensa: clean up word alignment macros in assembly codeMax Filippov
Remove duplicate definitions of ALIGN/src_b/__src_b and SSA8/ssa8/__ssa8 from assembly sources and put single definition into asm/asmmacro.h Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2017-12-10xtensa: clean up fixups in assembly codeMax Filippov
Remove duplicate definitions of EX() and similar TRY/CATCH and SRC/DST macros from assembly sources and put single definition into asm/asmmacro.h Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

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>
2012-12-18xtensa: clean up files to make them code-style compliantChris Zankel
Remove heading and trailing spaces, trim trailing lines, and wrap lines that are longer than 80 characters. Signed-off-by: Chris Zankel <chris@zankel.net>
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>
2005-06-24[PATCH] xtensa: Architecture support for Tensilica Xtensa Part 4Chris Zankel
The attached patches provides part 4 of an architecture implementation for the Tensilica Xtensa CPU series. Signed-off-by: Chris Zankel <chris@zankel.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
