checkpatch considered useful ;)

WARNING: macros should not use a trailing semicolon
#134: FILE: arch/sparc/include/asm/highmem.h:33:
+#define kmap_prot __pgprot(SRMMU_ET_PTE | SRMMU_PRIV | SRMMU_CACHE);

total: 0 errors, 1 warnings, 100 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

./patches/kmap-consolidate-kmap_prot-definitions.patch has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.

Please run checkpatch prior to sending patches
