[PATCH 2/4] UML - Remove unused sigcontext accessors

From: Jeff Dike
Date: Tue Feb 12 2008 - 13:58:16 EST


The macros which extract registers from a struct sigcontext are no
longer needed and can be removed. They are starting not to build
anyway, given the removal of the 'e' and 'r' from register names
during the x86 merge.
