[linux-yocto] [PATCH 05/14] Don't inline __const_udelay

[Alejandro Hernandez]

From: Andi Kleen <ak at linux.intel.com>

__const_udelay is marked inline, and LTO will happily inline it everywhere
Dropping the inline saves ~44k text in a LTO build.

13999560        1740864 1499136 17239560        1070e08 vmlinux-with-udelay-inline
13954764        1736768 1499136 17190668        1064f0c vmlinux-wo-udelay-inline

Even without LTO I believe marking it noinline documents it correctly.
