You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

Fixed thus.

Note that even with a _raw_read_trylock implementation, smp still
|
|
doesn't work. Everything that init spawns dies immediately. I
|
|
havn't had a chance to find out why yet...
|
|
|
|
[ Note: deleted changes to smp.c, since they didn't apply cleanly
|
|
to 2.6.11.3 (the function had moved, I guess), and they seemed unrelated.]
