posix_types: Remove fd_set macros
<asm/posix_types.h> includes a set of macros that operate on file descriptors. Way long ago those were exported to user space, but nowadays they are #ifdef __KERNEL__. However, they are nothing but standard (nonatomic) bit operations, and we already have optimized versions of bit operations in the kernel. We can't include <linux/bitops.h> in <asm/posix_types.h> but we can move the definitions to <linux/time.h> and define them there in terms of standard kernel bitops. [ v2: folds the following fixes in: a) Stray space in __FD_SET(), reported by Andrew Morton b) #include <linux/string.h> needed for memset(), reported by Tony Luck ] Signed-off-by: H.
