Subject: ARM: pgtable: get rid of TOP_PTE()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60db4fcf14c6b562399579473a67e51eed694ff4;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ARM: pgtable: get rid of TOP_PTE()

Get rid of the TOP_PTE() macro as we now have proper accessor functions
instead.  No one should be directly referencing the top pte table
anymore.
