[S390] Add PSW restart shutdown trigger

2011-08-03T14:44:19Z

With this patch a new S390 shutdown trigger "restart" is added. If under z/VM "systerm restart" is entered or under the HMC the "PSW restart" button is pressed, the PSW located at 0 (31 bit) or 0x1a0 (64 bit) bit is loaded. Now we execute do_restart() that processes the restart action that is defined under /sys/firmware/shutdown_actions/on_restart. Currently the following actions are possible: reipl (default), stop, vmcmd, dump, and dump_reipl. Signed-off-by: Michael Holzheu Signed-off-by: Heiko Carstens

[S390] xchg/cmpxchg: move to own header file

2011-03-23T09:15:59Z

Move xchg() and cmpxchg() functions to own header file like some other architectures have done. With this we make sure that system.h now really looks like a place where everything is gathered that doesn't fit anywhere else. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] Randomize lower bits of stack address

[S390] ptrace cleanup

Overhaul program event recording and the code dealing with the ptrace user space interface. Signed-off-by: Martin Schwidefsky

[S390] pfault: delay register of pfault interrupt

2011-01-05T11:47:26Z

Use an early init call to initialize pfault. That way it is possible to use the register_external_interrupt() instead of the early variant. No need to enable pfault any earlier since it has only effect if user space processes are running. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] cleanup facility list handling

2010-10-25T14:10:21Z

Store the facility list once at system startup with stfl/stfle and reuse the result for all facility tests. Signed-off-by: Martin Schwidefsky

[S390] switch_to: get rid of prev == next check

2010-10-25T14:10:16Z

schedule() makes sure that prev != next before calling switch_to(). Therefore remove the redundant check. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] switch_to: dont restore/save access & fpu regs for kernel threads

2010-10-25T14:10:16Z

If the previous task was a kernel thread there is no need to save the contents of the fpu and access registers since they aren't used in kernel mode. For the same reason it is not necessary to restore these registers if the next task is a kernel thread. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky
