  "message": "arch/tile: fix up locking in pgtable.c slightly\n\nWe should be holding the init_mm.page_table_lock in shatter_huge_page()\nsince we are modifying the kernel page tables.  Then, only if we are\nwalking the other root page tables to update them, do we want to take\nthe pgd_lock.\n\nAdd a comment about taking the pgd_lock that we always do it with\ninterrupts disabled and therefore are not at risk from the tlbflush\nIPI deadlock as is seen on x86.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n",
