[S390] Fix __ctl_load/__ctl_store inline assembly constraints

2008-06-10T08:03:28+00:00

__ctl_load/__ctl_store are called with either an array of unsigned long or a single unsigned long value. Add an address operator to the "m"/"=m" contraints to make them work for unsigned long arguments as well. Signed-off-by: Martin Schwidefsky

[S390] guest page hinting light

2008-05-07T07:23:02+00:00

Use the existing arch_alloc_page/arch_free_page callbacks to do the guest page state transitions between stable and unused. Acked-by: Rik van Riel Signed-off-by: Martin Schwidefsky

[S390] Convert machine feature detection code to C.

2008-04-30T11:38:47+00:00

From: Heiko Carstens From: Carsten Otte This lets us use defines for the magic bits in machine flags instead of using plain numbers all over the place. In addition on newer machines features/facilities are indicated by the result of the stfl instruction. So we use these bits instead of trying to execute new instructions and check wether we get an exception or not. Also the mvpg instruction is always available when in zArch mode, whereas the idte instruction is only available in zArch mode. This results in some minor optimizations.

Add cmpxchg_local to s390

2008-02-07T16:42:32+00:00

Use the standard __cmpxchg for every type that can be updated atomically. Use the new generic cmpxchg_local (disables interrupt) for other types. Signed-off-by: Mathieu Desnoyers Cc: Martin Schwidefsky Cc: Heiko Carstens Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[S390] Fix irq tracing and lockdep_sys_exit calls.

2007-11-20T10:13:45+00:00

Current support for TRACE_IRQFLAGS and lockdep_sys_exit is broken. IRQ flag tracing is broken for program checks. Even worse is that the newly introduced calls to lockdep_sys_exit are in the critical section code which is not supposed to call any C functions. In addition the checks if locks are still held are also done when returning to kernel code which is broken as well. Fix all this by disabling interrupts and machine checks at the exit paths and then do the appropriate checks and calls. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky
