sys/arch/x86/x86/pmap.c: revision 1.190
Operation pmap_pp_clear_attrs() may remove the "used" attribute from a page
that is still cached in the TLB of other CPUs.
Call pmap_tlb_shootnow() here before enabling preemption to clear the
TLB entries on other CPUs.
Should prevent tmpfs data corruption under load.
Ok: Chuck Silvers

fix broken error handling; error was used uninitialized. Changing the
compilation flags broke all threaded programs for me.

- If we succeeded allocating a buffer that did not need bouncing before, but
  the buffer in the previous mapping did, clear the bounce bit. Fixes the
  ld_virtio.c bug with machines 8GB and dd if=/dev/zero of=crash bs=1g count=4.
- Allocate with M_ZERO instead of doing memset
- The panic string can take a format, use it.
- When checking for the bounce buffer boundary check addr + len < limit, not
  addr < limit.
make sure we have a cookie before we try to clear it.
fix operator precedence.
