Subject: [PATCH 0/3] minor cleanups to EFLAGS initialisation in ret_from_fork
Date: Mon, 25 Jul 2011 10:58:03 +0100 [thread overview]
Message-ID: <1311587883.27940.20.camel@cthulhu.hellion.org.uk> (raw)
The following series removes the use of a global kernel_eflags variable
from the x86_64 ret_from_fork path and (very slightly) merges the 32 and
64 bit version of that code path.
kernel_eflags could be made a __read_mostly but actually there is no
reason to prefer the value at cpu_init() time to a compile time constant
value for the initial eflags after a fork.
Ian.
