xtensa: clean up functions in assembly code 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>

xtensa: clean up fixups in assembly code 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>

xtensa: replace variant/core.h with asm/core.h Introduce the header arch/xtensa/include/asm/core.h that provides definitions for XCHAL macros missing in older xtensa releases. Use this header instead of variant/core.h Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

[XTENSA] fix sources using deprecated assembler directive The assembler directive '.begin literal' is deprecated in the newer versions of the binutils (strncopy_user.S and strnlen_user.S). Signed-off-by: Chris Zankel <chris@zankel.net>

xtensa: abstract 'entry' and 'retw' in assembly code Provide abi_entry, abi_entry_default, abi_ret and abi_ret_default macros that allocate aligned stack frame in windowed and call0 ABIs. Provide XTENSA_SPILL_STACK_RESERVE macro that specifies required stack frame size when register spilling is involved. Replace all uses of 'entry' and 'retw' with the above macros. This makes most of the xtensa assembly code ready for XEA3 and call0 ABI. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
