| | |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This migrates SH7786 to evt2irq() backed hwirq lookup rather than using an open-coded calculation. This will make it possible to reposition the vector base at a later point in time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This unifies the fast-path TLB miss handler, allowing for further cleanup and eventual utilization of a shared _32/_64 handler. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the fast-path handler has been moved, we also need to update the Makefile to ensure that the same restrictions for caller-save registers are observed. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings the sh64 version in line with the sh32 one with regards to how errors are handled. Base work for further unification of the implementations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a method for finding out if we're handling an ITLB fault or not without passing it all the way down the chain, it's possible to use the __update_tlb() interface in place of a special __do_tlb_refill().

| * | | | sh: Enable shared page fault handler for _32/_64.Paul Mundt2012-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the now generic _32 page fault handling code to a shared place and adapts the _64 implementation to make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | | sh64: Kill off unused fixed I/O mapping window.Paul Mundt2012-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was reworked some time ago to go through fixmaps instead, leaving the range itself unused. As such, kill off the remaining references and hand over the remaining space for fixmaps directly. This also makes it possible to simplify the vmalloc fault case as we no longer have to care about the special section. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | | sh: Ensure fixmap and store queue space can co-exist.Paul Mundt2012-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment the top of the fixmap space is calculated from P4SEG, which places it at the end of the store queue space when that API is enabled. Make sure we use P3_ADDR_MAX here instead to find the proper address limit. With this done, it's also possible to switch to the generic vmalloc address range check now that VMALLOC_START/END encapsulate the translatable areas that we care about.

Given that we're also depending on register bank toggling for switch_to optimization we ought to also explicitly zero out the GP regs that reside in an alternate bank in order to prevent handing back garbage.
