2008-12-22sh: Add support for SH7201 CPU subtype.Peter Griffin
This patch adds support for the SH-2A FPU based SH7201 processor subtype. Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Switch HD64461 from hw_interrupt_type to irq_chipMatt Fleming
Use struct irq_chip for the interrupt handler for the HD64461. Also convert some in{b,w} and out{b,w} calls to the equivalent __raw_* calls. Include <linux/io.h> and not <asm/io.h> to stop checkpatch.pl complaining. This change should now allow machines with HD64461 to define GENERIC_HARDIRQS_NO__DO_IRQ.

2008-12-22sh: do not latency trace idle.Paul Mundt
Description snipped from Steven Rostedt's PPC patch: When idle is called, interrupts are blocked, but the idle function will still wake up on an interrupt. The problem is that the interrupt disabled latency tracer will take this call to idle as a latency. This patch disables the latency tracing when going into idle. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Tidy up backtrace formatting with kallsyms disabled.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Add a simple code dumper for SUPERH32 show_regs().Paul Mundt
This implements a simple show_code() that is in turn plugged in to show_regs() to provide minimal code dumping at the end of the trace. Built on top of a simple instruction disassembler derived from the binutils opcode table. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Add a few more branch types to the branch emulator.Paul Mundt
This plugs in some extra encodings for matching more bsr/bsrf/jsr branches. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Re-add support for best fit ISA tuning if none is available.Paul Mundt
This was removed in the libgcc integration, but there are still some compilers that need this. We also relax the rules on the ISA tuning in the cases where there are no matches for the CPU tuning and adopt the -any default, which matches the intent of the isa-y target list. This compensates for mismatches where binutils supports a wide array of targets whilst the compiler is much more restricted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: More movmem alias symbol exports for older compilers.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Provide optimized unaligned loads on SH-4A.Paul Mundt
This adds support for unaligned loads on SH-4A, using the SH-4A's neutered movua.l instruction. As movua.l is r0-inspired, stores are still handled through the packed struct. Based on asm-generic/unaligned.h by Harvey Harrison. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: P4 ioremap pass-throughMagnus Damm
This patch adds a pass-through case when ioremapping P4 addresses. Addresses passed to ioremap() should be physical addresses, so the best option is usually to convert the virtual address to a physical address before calling ioremap. This will give you a virtual address in P2 which matches the physical address and this works well for most internal hardware blocks on the SuperH architecture. However, some hardware blocks must be accessed through P4. Converting the P4 address to a physical and then back to a P2 does not work. One example of this is the sh7722 TMU block, it must be accessed through P4. Without this patch P4 addresses will be mapped using PTEs which requires the page allocator to be up and running.

2008-12-22sh: Migrate necessary libgcc bits in to arch/sh/lib for SUPERH32.Paul Mundt

2008-12-20Null pointer deref with hrtimer_try_to_cancel()Thomas Gleixner
Impact: Prevent kernel crash with posix timer clockid CLOCK_MONOTONIC_RAW commit 2d42244ae71d6c7b0884b5664cf2eda30fb2ae68 (clocksource: introduce CLOCK_MONOTONIC_RAW) introduced a new clockid, which is only available to read out the raw not NTP adjusted system time. The above commit did not prevent that a posix timer can be created with that clockid. The timer_create() syscall succeeds and initializes the timer to a non existing hrtimer base. When the timer is deleted either by timer_delete() or by the exit() cleanup the kernel crashes. Prevent the creation of timers for CLOCK_MONOTONIC_RAW by setting the posix clock function to no_timer_create which returns an error code.
