Arjan van de Ven c728252c7a [PATCH] x86/x86_64: mark rodata section read only: generic x86-64 bugfix 
Bug fix required for the .rodata work on x86-64:

when change_page_attr() and friends need to break up a 2Mb page into 4Kb
pages, it always set the NX bit on the PMD, which causes the cpu to consider
the entire 2Mb region to be NX regardless of the actual PTE perms.  This is
fine in general, with one big exception: the 2Mb page that covers the last
part of the kernel .text!  The fix is to not invent a new permission for the
new PMD entry, but to just inherit the existing one minus the PSE bit.
