  efi/libstub: Make efi_random_alloc() allocate below 4 GB on 32-bit (2016-11-22 09:53:49 +0000)

----------------------------------------------------------------
A single fix, for commit a6a144698d ("efi/libstub: Add random.c to ARM
build") that is queued for v4.10 in efi/core in the tip tree, since it
turned out that the compiler ends up emitting a call to a compiler
intrinsic to perform 64-bit logical shift when called with -Os. Upon
closer inspection of that code, it turned out we should explicitly ensure
that we do not allocate above 4 GB, which is not addressable by the stub
on 32-bit ARM.
