This patch makes arch-independent testcases for RODATA. Both x86 and x86_64 already have testcases for RODATA, But they are arch-specific because using inline assembly directly. And cacheflush.h is not a suitable location for rodata-test related things. Since they were in cacheflush.h, If someone change the state of CONFIG_DEBUG_RODATA_TEST, It cause overhead of kernel build. To solve the above issues, write arch-independent testcases and move it to shared location.

We already have the helper, we can convert the rest of the kernel mechanically using: git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own.

vsnprintf extension %Z<foo> is non-standard C. Suggest the use of %z instead. Miscellanea: - Correct the misuse of type string PRINTF_0xDECIMAL type strings are supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the type check in case I forget this again sometime in the future. - Improve the mechanism to find these defects so all 3 current checks are done on the format string [joe@perches.com: correct the misuse of type string PRINTF_0xDECIMAL, improve the mechanism to find these defects] Link: http://lkml.kernel.org/r/4e3ad74b0c9dc229b06018a2d79655308ddbbebd.1484014173.git.joe@perches.com Link: http://lkml.kernel.org/r/20170109235955.GA6787@avx2Signed-off-by:

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

I wrote a simple script to find new typo not in spelling.txt. (https://github.com/jinb-park/find-linux-kernel-typo) and get following result: [ rank ] 63 paramaters 18 alignement 9 strucuture .... The number means how many files include the typo. This patch adds these common typo. Link: http://lkml.kernel.org/r/20170112113452.GA7042@pjb1027-Latitude-E5410Signed-off-by:
