Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The end of the store queue bitmap is miscalculated when searching for a free range in sq_remap(), missing the PAGE_SHIFT shift that's done in sq_api_init(). This runs in to workloads where we can scan beyond the end of the bitmap.

This makes the early printk support somewhat more flexible, moving the port definition to a config option, and making the port initialization configurable for sh-ipl+g users. At the same time, this allows us to trivially wire up the SH7780 SCIF0, so that's thrown in too more or less for free. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

There were a number of places that made evil PAGE_SIZE == 4k assumptions that ended up breaking when trying to play with 8k and 64k page sizes, this fixes those up. The most significant change is the way we load THREAD_SIZE, previously this was done via: mov #(THREAD_SIZE >> 8), reg shll8 reg to avoid a memory access and allow the immediate load. With a 64k PAGE_SIZE, we're out of range for the immediate load size without resorting to special instructions available in later ISAs (movi20s and so on). The "workaround" for this is to bump up the shift to 10 and insert a shll2, which gives a bit more flexibility while still being much cheaper than a memory access.

There was a clobber issue with the register we were saving the stack in, so we switch to a register that we handle in the clobber list properly already. This also follows the x86 changes for allowing the softirq checks from hardirq context. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The implementation of system call tracing in the kernel has a couple of ordering problems: - the validity of the system call number is checked before calling out to system call tracing code, and should be done after - the system call number used when tracing is the one the system call was invoked with, while the system call tracing code can legitimatly change the call number (for example strace permutes fork into clone) This patch fixes both of these problems, and also reoders the code slightly to make the direct path through the code the common case.

This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes. This quickly got to be an unmaintainable mess, made even more evident by the subtle breakage introduced by the SH-2 and SH-2A changes. Now that subtypes are able to register IRQ maps directly, just rip all of the headers out. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: NJamie Lenehan <lenehan@twibble.org> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).

With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.

This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace().

Kill off interrupt_table for all of the CPU subtypes, we now default in to stepping in to do_IRQ() for _all_ IRQ exceptions and counting the spurious ones, rather than simply flipping on the ones we cared about. This and enabling the IRQ by default automatically has already uncovered a couple of bugs and IRQs that weren't being caught, as well as some that are being generated far too often (SCI Tx Data Empty, for example). The general rationale is to use a marker for interrupt exceptions, test for it in the handle_exception() path, and skip out to do_IRQ() if it's found. Everything else follows the same behaviour of finding the cached EXPEVT value in r2/r2_bank, we just rip out the INTEVT read from entry.S entirely (except for in the kGDB NMI case, which is another matter). Note that while this changes the do_IRQ() semantics regarding r4 handling, they were fundamentally broken anyways (relying entirely on r2_bank for the cached code). With this, we do the INTEVT read from do_IRQ() itself (in the CONFIG_CPU_HAS_INTEVT case), or fall back on r4 for the muxed IRQ number, which should also be closer to what SH-2 and SH-2A want anyways.

At the moment we wrap GENERIC_TIME around our existing timer API. As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

This adds the new kernel_execve function on all architectures that were using _syscall3() to implement execve. The implementation uses code from the _syscall3 macros provided in the unistd.h header file. I don't have cross-compilers for any of these architectures, so the patch is untested with the exception of i386. Most architectures can probably implement this in a nicer way in assembly or by combining it with the sys_execve implementation itself, but this should do it for now.
