| * mfd: do tcb6393xb state restore on resume only if requestedDmitry Baryshkov2008-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | As requested by Ian make state restore only if it's requested by platform data: some platforms do correctly save the state of the chip during suspend/resume, but some (like tosa) incorrectly power off the chip at suspend, so the driver supports restoring some bits of the tc6393xb state (not full, merely enough to support resume on tosa). With this patch this code is disabled by default. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Acked-by: Ian Molton <spyro@f2s.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

| | | | | | | | | | | | | | | | | | Instead of using bitfields for initial gpio setup, provide generic setup/teardown hooks that can be used to set the gpio states, register child devices, etc. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off. The ISA I/O routine wrapping remains unaffected, which remains the only special casing outside of the iomap API that boards need to think about. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | sh: Trivial trace_mark() instrumentation for core events.Paul Mundt2008-09-21

This implements a number of trace points: - The page fault handler / TLB miss - IPC calls - Kernel thread creation The original LTTng patch had the slow-path instrumented, which fails to account for the vast majority of events. In general placing this in the fast-path is not a huge performance hit, as we don't take page faults for kernel addresses. The other bits of interest are some of the other trap handlers, as well as the syscall entry/exit (which is better off being handled through the tracehook API). Most of the other trap handlers are corner cases where alternate means of notification exist, so there is little value in placing extra trace points in these locations. Based on top of the points provided both by the LTTng instrumentation patch as well as the patch shipping in the ST-Linux tree, albeit in a stripped down form.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows the powerpc commit f6a616800e68b61807d0f7bb0d5dc70665ef8046 '[POWERPC] Fix kernel stack allocation alignment'. SH has traditionally forced the thread order to be relative to the page size, so there were never any situations where the same bug was triggered by slub. Regardless, the usage of > 8kB stacks for the larger page sizes is overkill, so we switch to using slab allocations there, as per the powerpc change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This combination triggers a divide by zero in kernel/fork.c when calculating the initial max_threads value: max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE); Simply disable 4K stacks on 64kB PAGE_SIZE to work around this, as it's not a terribly useful combination to begin with.
