SubjectRE: Kernel 2.6.3 patch for Intel Compiler 8.0
Date
From
In 2.6, we already have sufficient changes for Intel IPF Compiler to
build the kernel, especially intrinscs changes, and you should not need
a patch. To make it faster, we might want to use PGO (profile guided
optimization) provided by the compiler; yes, it's available even for the
kernel with a driver.

Thanks,
Jun
