Subject: [PATCH 01/21] 2.6.18 perfmon2 : generic kernel modifications
This patch contains all the modified generic files:
linux/Makefile:
- create our own EXTRAVERSION
linux/include/linux/sched.h:
- add pfm_context pointer to struct task_struct. This is used
to connect a perfmon2 context to a task when doing per-thread
monitoring.
linux/include/linux/syscalls.h:
- declare prototypes of our new system calls
linux/kernel/sched.c:
- add include perfmon.h to ensure pfm_ctxsw() has a defined prototype
linux/kernel/sys_ni.c:
- add perfmon2 cond_syscall() definitions (when CONFIG_PERFMON is off)
