New Revision: 232475
URL: http://svn.freebsd.org/changeset/base/232475
Log:
On MIPS, _ALIGN always aligns to 8 bytes, even for 32-bit binaries. This
might
not be ideal, but is the ABI we've shipped so far. Fix macros which reflect
the results of _ALIGN on 32-bit MIPS to use the right alignment.
This fixes sendmsg under COMPAT_FREEBSD32 on n64 MIPS kernels.
