call. This uses the header files from a 32-bit Ubuntu Hardy system. The use of _LOOSE_KERNEL_NAMES seems right. The -D__ARCH_SI_UID_T works around a bug which appears to be fixed in later Linux versions. R=rsc http://go/go-review/1013015

2009-10-12stack overflow debugging and fix.Russ Cox6-24/+33
* in 6l, -K already meant check for stack underflow. add -KK to mean double-check stack overflows even in nosplit functions. * comment out print locks; they deadlock too easily but are still useful to put back for special occasions. * let runcgo assembly switch to scheduler stack without involving scheduler directly. because runcgo gets called from matchmg, it is too hard to keep it from being called on other stacks.
