[PATCH] tmpfs preempt count panic

Just unearthed another of my warcrimes: reading a 17-page sparse file,
I mean holey file, hits the in_interrupt panic in do_exit on a current
highmem kernel (but 2.6.7 is okay).  Fix mismatched preempt count from
shmem_swp_alloc's swapindex hole case by mapping an empty_zero_page.
