3.19.8-ckt16 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Mark Rutland <mark.rutland@arm.com>

commit 236cf17c2502007a9d2dda3c39fb0d9a6bd03cc2 upstream.

When we allocate bitmaps in vgic_vcpu_init_maps, we divide the number of
bits we need by 8 to figure out how many bytes to allocate. However,
bitmap elements are always accessed as unsigned longs, and if we didn't
happen to allocate a size such that size % sizeof(unsigned long) == 0,
bitmap accesses may go past the end of the allocation.

When using KASAN (which does byte-granular access checks), this results
in a continuous stream of BUGs whenever these bitmaps are accessed:

=============================================================================

==================================================================

Fix the issue by always allocating a multiple of sizeof(unsigned long),
as we do elsewhere in the vgic code.
