sh-sci was turning in to an unmaintainable mess, especially with regards to the port list. This cleans it up quite a bit, and switches over to a platform device model where subtypes will register their port list individually in their setup code. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Some kgdb cleanup. Move hexchars/highhex/lowhex to the header, so it can be reused by sh-sci. Also drop silly ctrl_inl/outl() overloading being done by the kgdb stub. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Drop _PAGE_SHARED/_PAGE_U0_SHARED and document Linux PTE encodings in the PTEL value. Preserve the swap cache entry encoding semantics for now, though it will need rework to free up _PAGE_WT from _PAGE_FILE. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Rewrite the store queue API for a per-cpu interface in the driver model. The old miscdevice is dropped, due to TASK_SIZE limitations, and no one was using it anyways. Carve up and allocate store queue space with a bitmap, back sq mapping objects with a slab cache, and let userspace worry about its own prefetching. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

ioremap() overhaul. Add support for transparent PMB mapping, get rid of p3_ioremap(), etc. Also drop ioremap() and iounmap() routines from the machvec, as everyone can use the generic ioremap() API instead. For PCI memory apertures and other special cases, use the pci_iomap() API, as boards are already required to get the mapping right there. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Cleanup of page table allocators, using generic folded PMD and PUD helpers. TLB flushing operations are moved to a more sensible spot. The page fault handler is also optimized slightly, we no longer waste cycles on IRQ disabling for flushing of the page from the ITLB, since we're already under CLI protection by the initial exception handler.

A synco is needed before we jump to start_kernel(). While we're at it, also move the sh_cpu_init() jump until after we've zeroed BSS, as this has caused some undesirable results in sh_cpu_init(). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Currently when making changes to control registers, we typically need some time for changes to take effect (8 nops, generally). However, for sh4a we simply need to do an icbi.. This is a simple patch for implementing a general purpose ctrl_barrier() which functions as a control register write barrier. There's some additional documentation in the patch itself, but it's pretty self explanatory. There were also some places where we were not doing the barrier, which didn't seem to have any adverse effects on legacy parts, but certainly did on sh4a. It's safer to have the barrier in place for legacy parts as well in these cases, though this does make flush_tlb_all() more expensive (by an order of 8 nops). We can ifdef around the flush_tlb_all() case for now if it's clear that all legacy parts won't have a problem with this. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

There's a bug in the Hitachi SuperH csum_partial_copy_generic() implementation. If the supplied length is 1 (and several alignment conditions are met), the function immediately branches to label 4. However, the assembly at label 4 expects the length to be stored in register r2. Since this has not occurred, subsequent behavior is undefined. This can cause bad payload checksums in TCP connections. I've fixed the problem by initializing register r2 prior to the branch instruction.

We had a pretty interesting oops happening, where copy_user_page() was down()'ing p3map_sem[] with a bogus offset (particularly, an offset that hadn't been initialized with sema_init(), due to the mismatch between cpu_data->dcache.n_aliases and what was assumed based off of the old CACHE_ALIAS value). Luckily, spinlock debugging caught this for us, and so we drop the old hardcoded CACHE_ALIAS for sh4 completely and rely on the run-time probed cpu_data->dcache.alias_mask. This in turn gets the p3map_sem[] index right, and everything works again. While we're at it, also convert to 4-level page tables.. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
