[PATCH] xtensa: remove extra header files 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.

xtensa: limit offsets in __loop_cache_{all,page} When building kernel for xtensa cores with big cache lines (e.g. 128 bytes or more) __loop_cache_all and __loop_cache_page may generate assembly instructions with immediate fields that are too big. This results in the following build errors: arch/xtensa/mm/misc.S: Assembler messages: arch/xtensa/mm/misc.S:464: Error: operand 2 of 'diwbi' has invalid value '256' arch/xtensa/mm/misc.S:464: Error: operand 2 of 'diwbi' has invalid value '384' arch/xtensa/kernel/head.S: Assembler messages: arch/xtensa/kernel/head.S:172: Error: operand 2 of 'diu' has invalid value '256' arch/xtensa/kernel/head.S:172: Error: operand 2 of 'diu' has invalid value '384' arch/xtensa/kernel/head.S:176: Error: operand 2 of 'iiu' has invalid value '256' arch/xtensa/kernel/head.S:176: Error: operand 2 of 'iiu' has invalid value '384' arch/xtensa/kernel/head.S:255: Error: operand 2 of 'diwb' has invalid value '256' arch/xtensa/kernel/head.S:255: Error: operand 2 of 'diwb' has invalid value '384' Add parameter max_immed to these macros and use it to limit values of immediate operands.

[PATCH] xtensa: remove extra header files 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.

xtensa: limit offsets in __loop_cache_{all,page} When building kernel for xtensa cores with big cache lines (e.g. 128 bytes or more) __loop_cache_all and __loop_cache_page may generate assembly instructions with immediate fields that are too big.
