Subject: [PATCH] sparc64: fix sparse warnings in sys_sparc32.c

Fix following warnings:
sys_sparc32.c:52:17: warning: symbol 'sys32_truncate64' was not declared. Should it be static?
sys_sparc32.c:60:17: warning: symbol 'sys32_ftruncate64' was not declared. Should it be static?
sys_sparc32.c:98:17: warning: symbol 'compat_sys_stat64' was not declared. Should it be static?
sys_sparc32.c:109:17: warning: symbol 'compat_sys_lstat64' was not declared. Should it be static?
sys_sparc32.c:120:17: warning: symbol 'compat_sys_fstat64' was not declared. Should it be static?
sys_sparc32.c:131:17: warning: symbol 'compat_sys_fstatat64' was not declared. Should it be static?
sys_sparc32.c:196:27: warning: symbol 'sys32_pread64' was not declared. Should it be static?
sys_sparc32.c:205:27: warning: symbol 'sys32_pwrite64' was not declared. Should it be static?
sys_sparc32.c:214:17: warning: symbol 'compat_sys_readahead' was not declared. Should it be static?
sys_sparc32.c:222:6: warning: symbol 'compat_sys_fadvise64' was not declared. Should it be static?
sys_sparc32.c:230:6: warning: symbol 'compat_sys_fadvise64_64' was not declared. Should it be static?
sys_sparc32.c:241:6: warning: symbol 'sys32_sync_file_range' was not declared. Should it be static?
sys_sparc32.c:249:17: warning: symbol 'compat_sys_fallocate' was not declared. Should it be static?

Add proper prototypes in systbls.h
Include linux/compat.h to get access to necessary types
Use inverse christmas tree order in includes
