Well, I might do if you told me that your changes conflict with Will's
idmap changes in arch/arm/mm/idmap.c:

++<<<<<<< HEAD
 +extern char  __idmap_text_start[], __idmap_text_end[];
++=======
+ #ifdef CONFIG_SMP
+ static void idmap_del_pmd(pud_t *pud, unsigned long addr, unsigned long end)
+ {
+       pmd_t *pmd;
+
+       if (pud_none_or_clear_bad(pud))
+               return;
+       pmd = pmd_offset(pud, addr);
+       pmd_clear(pmd);
+ }
++>>>>>>> cf9a53fb7cf8dd2fd2b5d7bb07434bd2ebeb5a8f

I'm assuming that idmap_del_pmd() just gets deleted?

Alternatively, if you wish to fix the dependencies of your commits and
resubmit a pull request, let me know.
