CRIS: Export missing function symbols

2014-12-19T23:03:22+00:00

strcmp was lost when all other string functions were removed, but we still have an optimized version for this on CRISv32, so any driver built as a module would not have access to this symbol. In a similar manner, we had optimized versions of csum_partial_copy_from_user and __do_clear_user but no exported symbols for them, breaking bunch of other drivers when built as a module. At the same time, move EXPORT_SYMBOL(__copy_user) and EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's located together with the function definition. Signed-off-by: Jesper Nilsson

cris: Remove old legacy "-traditional" flag from arch-v10/lib/Makefile

2012-04-19T09:17:04+00:00

Most of these have been purged years ago. This one silently lived on until commit 69349c2dc01c489eccaa4c472542c08e370c6d7e "kconfig: fix IS_ENABLED to not require all options to be defined" In the above, we use some macro trickery to create a conditional that is valid in CPP and in C usage. However that trickery doesn't sit well if you have the legacy "-traditional" flag enabled. You'll get: AS arch/cris/arch-v10/lib/checksum.o In file included from :4:0: include/linux/kconfig.h:23:0: error: syntax error in macro parameter list make[2]: *** [arch/cris/arch-v10/lib/checksum.o] Error 1 Everything builds fine w/o "-traditional" so simply drop it from this location as well.

In particular, several occurances of funny versions of 'success', 'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address', 'beginning', 'desirable', 'separate' and 'necessary' are fixed. Signed-off-by: Daniel Mack Cc: Joe Perches Cc: Junio C Hamano Signed-off-by: Jiri Kosina

cris: correct usage of __user for copy to and from user space in lib/usercopy and uaccess.h

2008-03-05T00:35:16+00:00

Function __copy_user_zeroing in arch/lib/usercopy.c had the wrong parameter set as __user, and in include/asm-cris/uaccess.h, it was not set at all for some of the calling functions. This will cut the number of warnings quite dramatically when using sparse. While we're here, remove useless CVS log and correct confusing typo.

CRIS: Import string.c (memcpy) from newlib: fixes compile error with gcc 4

2008-03-05T00:35:13+00:00

Adrian Bunk reported another compile error with a SVN head GCC: ... CC arch/cris/arch-v10/lib/string.o /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:139: error: lvalue required as increment operand ... This is due to the use of the construct: *((long*)dst)++ = lc; Which isn't legal since casts don't return an lvalue. The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors. As for the earlier fix for memset.c, even if the two files for CRIS v10 and CRIS v32 are identical at the moment, it might be possible to tweak the CRIS v32 version. Thus, I'm not yet folding them into the same file, at least not until we've done some research on it.
