Subject: [PATCH 09/27] [AARCH64] Use PTR_REG in getcontext.S.

From: Andrew Pinski <apinski@...ium.com>

Just like the other patches, this patch allows for getcontext.S to be used
between ILP32 and LP64.

* sysdeps/unix/sysv/linux/aarch64/getcontext.S: Use PTR_REG when
doing an add so wrapping of the pointer is correct for ILP32.
