+    
+    Currently, it's difficult to find all the workarounds that are
+    applied when running on EFI, because they're littered throughout
+    various code paths. This change moves all of them into a separate
+    file with the hope that it will be come the single location for all
+    our well documented quirks.

     Fix the problem by changing init_cma_reserved_pageblock() such that it

     In cases where !CONFIG_HUGETLB_PAGE_SIZE_VARIABLE, which is all
     architectures expect for ia64, powerpc and tile at the moment, the
     “pageblock_order > MAX_ORDER” condition will be optimised out since
-    both sides of the operator are constants.  In cases where pageblock
-    size is variable, the performance degradation should not be
-    significant anyway since init_cma_reserved_pageblock() is called
-    only at boot time at most MAX_CMA_AREAS times which by default is
