Currently dev/mem for s390 provides only real memory access. This means that the CPU prefix pages are swapped. The prefix swap for real memory works as follows: Each CPU owns a prefix register that points to a page aligned memory location "P". If this CPU accesses the address range [0,0x1fff], it is translated by the hardware to [P,P+0x1fff]. Accordingly if this CPU accesses the address range [P,P+0x1fff], it is translated by the hardware to [0,0x1fff]. Therefore, if [P,P+0x1fff] or [0,0x1fff] is read from the current /dev/mem device, the incorrectly swapped memory content is returned. With this patch the /dev/mem architecture code is modified to provide absolute memory access. This is done via the arch specific functions xlate_dev_mem_ptr() and unxlate_dev_mem_ptr(). For swapped pages on s390 the function xlate_dev_mem_ptr() now returns a new buffer with a copy of the requested absolute memory. In case the buffer was allocated, the unxlate_dev_mem_ptr() function frees it after /dev/mem code has called copy_to_user(). Signed-off-by:

wait_cons_dev waits for a particular subchannel to complete an I/O. It is not necessary to use tpi to get the subchannel id as it is already known. This avoids changes to the interrupt subclass mask and allows to remove the lock & unlock of the subchannel lock. Signed-off-by:

Various improvements of qdio error reporting to the upper-layer drivers (qeth, zfcp): - Split QDIO_ERROR_ACTIVATE_CHECK_CONDITION into: QDIO_ERROR_ACTIVATE: qdio termination interrupt QDIO_ERROR_GET_BUF_STATE: QIOASSIST eqbs error QDIO_ERROR_SET_BUF_STATE: QIOASSIST sqbs error Add QDIO_ERROR_FATAL / QDIO_ERROR_TEMPORARY masks to ease recovery decision in upper-layer drivers. - Don't (ab-)use qdio handler errors as return codes for do_QDIO but use standard error codes: -ENOBUFS: temporary target CC=2 condition -EBUSY: unresolved SIGA-W CC=2 busy condition -EIO: I/O error (CC=1, CC=3) - Remove unneeded memory clobber from SIGA-R - Remove EX_TABLE entry on SIGA-W, we want to see these errors Reviewed-by:

Export handle_edge_irq() and irq_to_desc() to modules to allow them to do things such as __irq_set_handler_locked(...., handle_edge_irq); This fixes ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined! ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined! when gpio-pch is being built as a module. This was introduced by commit df9541a6 ("gpio: pch9: Use proper flow type handlers") that added __irq_set_handler_locked(d->irq, handle_edge_irq); but handle_edge_irq() was not exported for modules (and inlined __irq_set_handler_locked() requires irq_to_desc() exported as well) Signed-off-by:

Commit 069d4e74 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds. Signed-off-by:

Fix SMP TWD boot regression on sh73a0 based platforms caused by: 4200b16d ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on sh73a0 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time.
