2009-11-18sysctl: Drop & in front of every proc_handler.Eric W. Biederman1-3/+3
For consistency drop & in front of every proc_handler. Explicity taking the address is unnecessary and it prevents optimizations like stubbing the proc_handlers to NULL.

2009-11-12sysctl sh: Remove dead binary sysctl supportEric W. Biederman1-6/+1
Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name and .strategy members of sysctl tables are dead code. Remove them. Also add an C99 named initializer to the child member of unaligned_root to prevent chaos as the ctl_table definition changes over time. Cc: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Eric W.

2009-11-09sh: Account for cache aliases in flush_icache_range()Matt Fleming1-1/+4
The icache may also contain aliases so we must account for them just like we do when manipulating the dcache. We usually get away with aliases in the icache because the instructions that are read from memory are read-only, i.e. they never change. However, the place where this bites us is when the code has been modified. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-11-06sh: unwinder: Fix up invalid PC refetch in dwarf unwinder.Paul Mundt1-1/+1
The dwarf unwinder presently attempts to provide a sane PC value if none is provided, however the logic is broken and cases where a previous valid dwarf frame exists along with a bogus PC value can still proceed. This fixes up the test and prevents the unwinder from blowing up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-11-04ALSA: sh: add SuperH DAC audio driver for ALSA V4Rafael Ignacio Zurita2-0/+59
This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx). Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed.

2009-10-27sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.Paul Mundt2-1/+6
The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming1-0/+22
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

2009-10-26sh: __irq_entry annotate do_IRQ().Paul Mundt1-1/+2
This adds an __irq_entry annotation for do_IRQ() so that the IRQ annotation in the function graph tracer works as advertized. We already have the IRQENTRY section wired up, so this is just a trivial addition to actually make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-16sh: Remove BKL from landisk gio.Thomas Gleixner1-6/+4
The open function got the BKL via the big push down. Replace it by preempt_enable/disable as this is sufficient for an UP machine. The ioctl can be unlocked because there is no functionality which requires serialization. The usage by multiple callers is broken with and without the BKL due to the local static variable addr.

2009-10-16sh: disabled cache handling fix.Magnus Damm1-0/+10
Add code to handle the cache disabled case. Fixes breakage introduced by 37443ef3f0406e855e169c87ae3f4ffb4b6ff635 ("sh: Migrate SH-4 cacheflush ops to function pointers."). Without this patch configuring caches off with CONFIG_CACHE_OFF=y makes kfr2r09 and migo-r lock up in fbdev deferred io or early user space.

2009-10-16sh: Fix up single page flushing to use PAGE_SIZE.Valentin Sitdikov1-12/+10
Presently The SH-4 cache flushing code uses flush_cache_4096() for most of the real flushing work, which breaks down to a fixed 4096 unroll and increment. Not only is this sub-optimal for larger page sizes, it's also uncovered a bug in sh4_flush_dcache_page() when large page sizes are used and we have no cache aliases -- resulting in only a part of the page's D-cache lines being written back.

2009-10-14sh: Fix a TRACE_IRQS_OFF typo.Paul Mundt1-1/+1

2009-10-14sh: Optimize the setup_rt_frame() I-cache flush.Paul Mundt1-2/+1
This only needs to flush the return code via the legacy path, and just invalidates uselessly otherwise. This makes the behaviour consistent for all of the trampoline setup paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-14sh: Populate initial secondary CPU info from boot_cpu_data.Paul Mundt1-0/+2
The secondary CPU info was seeing corrupted results due to not entering all of the setup paths taken by the boot CPU. So we just memcpy() the boot cpu data over directly, and then fix up the per-CPU bits. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-14sh: Tidy up SMP cpuinfo.Paul Mundt1-0/+2
Trivial change for cleaning up the cpuinfo pretty printing on SMP, adds a newline between CPUs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-14sh: Use boot_cpu_data for FPU tests in sigcontext paths.Paul Mundt1-3/+3
We do not want to use smp_processor_id() from these paths, as they trip preempt BUGs. Switch the test over to the boot cpu directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-13sh: ftrace: Fix up syscall tracepoint support.Paul Mundt1-10/+27

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-13sh: force dcache flush if dcache_dirty bit set.Paul Mundt1-1/+1
This too follows the ARM change, given that the issue at hand applies to all platforms that implement lazy D-cache writeback. This fixes up the case when a page mapping disappears between the flush_dcache_page() call (when PG_dcache_dirty is set for the page) and the update_mmu_cache() call -- such as in the case of swap cache being freed early. This kills off the mapping test in update_mmu_cache() and switches to simply testing for PG_dcache_dirty.

2009-10-13sh: update die() output.Paul Mundt1-3/+4
This follows the ARM change, as SH had all of the same issues: Make die() better match x86: - add printing of the last accessed sysfs file - ensure console_verbose() is called under the lock - ensure we panic outside of oops_exit() Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-09sh: Don't allocate smaller sized mappings on every iterationMatt Fleming1-0/+7
Currently, we've got the less than ideal situation where if we need to allocate a 256MB mapping we'll allocate four entries like so, entry 1: 128MB entry 2: 64MB entry 3: 16MB entry 4: 16MB This is because as we execute the loop in pmb_remap() we will progressively try mapping the remaining address space with smaller and smaller sizes. This isn't good because the size we use on one iteration may be the perfect size to use on the next iteration, for instance when the initial size is divisible by one of the PMB mapping sizes. With this patch, we now only need two entries in the PMB to map 256MB of address space, entry 1: 128MB entry 2: 128MB Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-09sh: Plug PMB alloc memory leakMatt Fleming1-6/+24

2009-09-28sh: Don't enable interrupts in the page fault pathMatt Fleming1-2/+0

2009-09-28sh: Set the default I/O port base to P2SEG.Paul Mundt1-0/+3
This bumps up the default I/O base to P2SEG, which allows legacy probing to bail out gracefully rather than oopsing. Platforms that have a real PIO offset still need to fix this up on their own, although most platforms are content with P2SEG already. The previous change to teach ioport_map() about >= P1SEG offsets in combination with this patch allows both the already remapped and the legacy address probing to pass through and succeed. Fixes up an oops with i8042 on the sh7785lcr board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
