2008-09-12sh: Tidy up ELF core dumps.Paul Mundt4-40/+0
These have been using overrides for ELF_CORE_COPY_TASK_REGS and ELF_CORE_COPY_FPREGS while the generic versions can be used instead. Presently the pt_regs are also duplicated across elf_core_copy_regs() and elf_core_copy_task_regs(), this switches to simply copying out through elf_core_copy_regs() instead.

bit is unsigned, so test before subtraction Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-09sh: kprobes: kretprobe_trampoline needs to be global.Paul Mundt1-1/+3
Needed by CONFIG_TRACING. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-09sh: Add R2D+ defconfig for qemu system emulator.Paul Mundt1-0/+909
This adds a defconfig for the R2D+ target in the qemu system emulator. Eventually it will be possible to simply use the r2d+ defconfig as it is. Provided by Shin-ichiro KAWASAKI. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul1-0/+2
Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.

2008-09-08sh: Derive calibrate_delay lpj from clk fwk.Paul Mundt2-1/+22
All CPUs must have a sensible cpu_clk definition these days, which we can safely use for deriving the preset loops_per_jiffy. The only odd one out is SH-5, which hasn't been hammered in to the framework yet. Based on the ST patch.

2008-09-08sh: kprobes: Fix up race against probe point removal.Paul Mundt1-0/+11
Handle a corner case where another CPU or debugger removes the probe point from underneath us. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: kprobes: Fix up a preemption imbalance on jprobe return.Paul Mundt1-0/+1
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: kprobes: Default to NOTIFY_DONE for unhandled debug traps.Paul Mundt1-1/+1
Presently this is doing a force_sig() SIGTRAP, which is already taken care of in the generic code if no one asserts NOTIFY_STOP. Switch the default return to NOTIFY_DONE in the case of unhandled traps, so that the same trap may pass through to other users on the same die chain. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: kprobes: Use trapa #0x3a for breakpoint trap.Paul Mundt2-3/+2
Not all parts support trapa #0xff, so use something within the debug trap range that's accessible on all parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: Disable seccomp support by default.Paul Mundt1-1/+0
This was initially checked in with a stupid default of y, while most everyone is going to want to have this disabled anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: uninline flush_icache_all().Paul Mundt1-1/+1
This uses jump_to_uncached() which is now given the noinline attribute due to the special section mapping. Kill off the inline attribute to fix up compilation failure. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: remove unnecessary memset after alloc_bootmem_low_pagesMarek Skuczynski1-1/+0
Because alloc_bootmem functions return the allocated memory always zeroed, an additional call of memset on allocated memory is unnecessary. Signed-off-by: Marek Skuczynski <M.Skuczynski@adbglobal.com> Signed-off-by: Carl Shaw <carl.shaw@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: Subnormal double to float conversionCarl Shaw2-1/+53
This patch adds support for the SH4 to convert a subnormal double into a float by catching the FPE and implementing the FCNVDS instruction in software. Signed-off-by: Carl Shaw <carl.shaw@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: Fix an unusual memory initialisation error.Stuart Menefy1-4/+6
This fixes a problems with the set up of Linux memory: - When reserving memory at boot time, the code previously reserved the bottom page of memory, and then from one page up to the end of the bootmap. This had the desired effect, but was strictly speaking wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET had been set to.

2008-09-08sh: Fix uImage load address in 32-bit mode.Chris Smith1-0/+6

2008-09-08sh: vmalloc pgtable sync fix.Stuart Menefy1-4/+7
This fixes a problem in the code which copies the vmalloc portion of the kernel's page table into the current user space page table. The addition of the four level page table code breaks on folded page tables, because the pud level is always present (although folded). This updates the code to use the same style of updates for the pud as is used for the pgd level. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: Don't enable clockevents broadcasting on UP SH-X3 builds.Paul Mundt1-1/+1
Fixes up compile errors with missing timer definitions. It's pointless to have this enabled anyways if CONFIG_SMP=n. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
