Subject: x86/mm: Add parenthesis for TLB tracepoint size calculation
From: Dave Hansen <[email protected]>
commit bbc03778b9954a2ec93baed63718e4df0192f130 upstream.
flush_tlb_info->flush_start/end are both normal virtual
addresses. When calculating 'nr_pages' (only used for the
tracepoint), I neglected to put parenthesis in.
Thanks to David Koufaty for pointing this out.
