Subject: [patch 27/28] Introduce U16_MAX and U32_MAX
From: Satyam Sharma <satyam@...radead.org>
... in kernel.h and clean up home-grown macros elsewhere in the tree.
Leave out the one in reiserfs_fs.h as it is in the userspace-visible part
of that header. Still, #undef the (equivalent) kernel version there to
avoid seeing "redefined, previous definition was here" gcc warnings.
[akpm@...ux-foundation.org: fix U16_MAX, U32_MAX defns]
