This renames include/asm-h8300/timer.h into arch/h8300/include/asm: it was left over just because that file had been created in the -mm tree before the whole h8300 header subdirectory had been moved, and then got merged in the old location afterwards. (See commitse0b0f9e4ea: "h8300: update timer handler - new files" and758db3f211: "[h8300] move include/asm-h8300 to arch/h8300/include/asm" for details). This also removes a left-over .gitignore file in include/asm-arm that became stale when the ARM header files were moved (which happened in multiple commits, just see "git log -- include/asm-arm" for details).
