Subject: x86: don't set pagetable_setup_{start,done} hooks on 64-bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8dd8eec57254adac48e46c6d191cb24161d8b4d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

x86: don't set pagetable_setup_{start,done} hooks on 64-bit

paravirt_pagetable_setup_{start,done}() are not used (yet) under x86_64,
and native_pagetable_setup_{start,done}() don't exist on x86_64. So they
don't need to be set.
