Nadav Amit ca309fef7a x86/kprobes: Set instruction page as executable
[ Upstream commit 7298e24f90 ]

Set the page as executable after allocation.  This patch is a
preparatory patch for a following patch that makes module allocated
pages non-executable.

While at it, do some small cleanup of what appears to be unnecessary
masking.
