Needed by CONFIG_TRACING. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-09sh: Add R2D+ defconfig for qemu system emulator.Paul Mundt
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>
2008-09-08sh: Derive calibrate_delay lpj from clk fwk.Paul Mundt
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 Mundt
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>

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: kprobes: Default to NOTIFY_DONE for unhandled debug traps.Paul Mundt
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 Mundt
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 Mundt
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 Mundt
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 Skuczynski
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 Shaw
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 Menefy
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 Smith

2008-09-08sh: vmalloc pgtable sync fix.Stuart Menefy
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 Mundt
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>

2008-09-08sh: Early dummy clockevent registration on boot CPU.Paul Mundt
The dummy timer needs to be registered on the boot CPU before the system timer clockevent is registered, or broadcasting doesn't work as advertized. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: smp: shove a cpu_relax() in the plat_start_cpu() busy loop.Paul Mundt
Without this, certain versions of GCC will happily optimize the entire loop out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: generic clockevent broadcast support.Paul Mundt
This hooks up GENERIC_CLOCKEVENTS_BROADCAST and a dummy local timer, which we call in to from the timer IPI when no other local timer is provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-08sh: smp: Provide a generic IPI handler.Paul Mundt
This provides a generic smp_message_recv() routine (based on the PPC one), that IPI IRQs can wrap in to. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Follows the SH change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-05sh: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.Carmelo Amoroso
This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

2008-08-28sh: fix kexec entry point for crash kernelsMagnus Damm
The crash kernel entry point is currently checked by the kexec kernel code and only physical addresses in the reserved memory window are accepted. This means that we can't pass P2 or P1 addresses as entry points in the case of crash kernels. This patch makes sure we can start crash kernels by adding support for physical address entry points.
