[Xen-devel] [RFC 01/22] x86/crypto: Adapt assembly for PIE support



Change the assembly code to use only relative references of symbols for the
kernel to be PIE compatible.

Position Independent Executable (PIE) support will allow to extended the
KASLR randomization range below the -2G memory limit.
