2014-05-18sparc32: remove cast from output constraints in math asm statementsSam Ravnborg1-10/+10
The following asm statements generated a sparse warning: asm("addcc \n\t" : "=r" (((USItype)(r2))) warning: asm output is not an lvalue When asking on the sparse mailing list Linus replyed: " Those casts to (USItype) are all pointless to begin with (since the values are of that type already!) and they mean that the expression isn't something you can assign to (lvalue). " In the math emulation code drop all casts in the output parts of the asm statements. This fixes a lot of "warning: asm output is not an lvalue" sparse warnings in math_32.c.

2010-05-26Revert "endian: #define __BYTE_ORDER"Linus Torvalds1-0/+6
This reverts commit b3b77c8caef1750ebeea1054e39e358550ea9f55, which was also totally broken (see commit 0d2daf5cc858 that reverted the crc32 version of it). As reported by Stephen Rothwell, it causes problems on big-endian machines: > In file included from fs/jfs/jfs_types.h:33, > from fs/jfs/jfs_incore.h:26, > from fs/jfs/file.c:22: > fs/jfs/endian24.h:36:101: warning: "__LITTLE_ENDIAN" is not defined The kernel has never had that crazy "__BYTE_ORDER == __LITTLE_ENDIAN" model. It's not how we do things, and it isn't how we _should_ do things. So don't go there. Requested-by: Stephen Rothwell <> Signed-off-by: Linus Torvalds <>
2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund1-6/+0
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.
