Commit3cbe6b2

committed

Looks like a small patch is needed as well to do the right thing on Linux.

The patch enables the mips2 ISA for the ll/sc operations, and then restoresit when done. The kernel/libc emulation code will take over on CPUs withoutll/sc, and on CPUs with it, it'll use the operations provided by the CPU.Combined with the earlier fix (removing -mips2), postgresql builds again onmips and mipsel. The patch is against 7.2-7.Oliver Elphick
