[43/67] sparc32: Be less strict in matching %lo part of relocation.

[Greg KH]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------


From: "David S. Miller" <davem@xxxxxxxxxxxxx>

[ Upstream commit b1f44e13a525d2ffb7d5afe2273b7169d6f2222e ]

The "(insn & 0x01800000) != 0x01800000" test matches 'restore'
but that is a legitimate place to see the %lo() part of a 32-bit
symbol relocation, particularly in tail calls.
