Hello Andi,
The following emails contain the patches to convert x86-64 to store current
in r10 (also at http://www.kvack.org/~bcrl/patches/v2.6.15-rc3/). This
provides a significant amount of code savings (~43KB) over the current
use of the per cpu data area. I also tested using r15, but that generated
code that was larger than that generated with r10. This code seems to be
working well for me now (it stands up to 32 and 64 bit processes and ptrace
users) and would be a good candidate for further exposure.
