When we set the sun4u version of the PTE execute bit, it's: or REG, _PAGE_EXEC_4U, REG _PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the 'or' instruction is a signed 13-bit value. So the above actually assembles into: or REG, -4096, REG completely corrupting the final PTE value. Set it with a: sethi %hi(_PAGE_EXEC_4U), TMP or REG, TMP, REG sequence instead. This fixes "git gc" crashes on sun4u machines. Reported-by: Meelis Roos <mroos@linux.ee> Signed-off-by: David S. Miller <davem@davemloft.net> |
