Description Luming Yu 2007-05-28 10:37:14 EDT
Description of problem:

Recently Fenghua implemented getcpu system call for IPF that is

a clean interface to get the CPU and node number a process is running on.

There is  /proc/<pid>/stat, but that is not a well documented API that

can be used in production systems. Andi added a system call in x86-64 that 
does this




The implementation includes both sys_getcpu and fsys_getcpu.



sys_getcpu patch can be found at:
