* PTRACE_POKEDATA consolidationAlexey Dobriyan2007-07-17
| | | | | | | | | | | | | | Identical implementations of PTRACE_POKEDATA go into generic_ptrace_pokedata() function. AFAICS, fix bug on xtensa where successful PTRACE_POKEDATA will nevertheless return EPERM.

* Report that kernel is tainted if there was an OOPSPavel Emelianov2007-07-17
| | | | | | | | | | | | | | If the kernel OOPSed or BUGed then it probably should be considered as tainted. Thus, all subsequent OOPSes and SysRq dumps will report the tainted kernel. This saves a lot of time explaining oddities in the calltraces.

| * sh: Export div symbols for GCC 4.2 and ST GCC.Paul Mundt2007-07-12
| | | | | | | | | | | | | | | | | | | | | | | | GCC 4.2 can emit integer variants of the FP division routines, so these need to be exported in order to keep the modules happy. 4.1.x versions of the ST compiler have these things backported, and so also generate these symbols (whereas vanilla gcc 4.1.x does not), so handle the __GNUC_STM_RELEASE__ case to accomodate updated versions of the 4.1.x toolchain.

| * sh: fix race in parallel out-of-tree buildErik Johansson2007-07-12
| | | | | | | | | | | | | | | | | | | | | | Depending on which of the three dependencies for archprepare (in arch/sh/Makefile) get built first, the directory include/asm-sh may or may not exist when the maketools target is built. If the directory does not exist, awk will fail to generate machtypes.h. This patch fixes this by creating the directory before awk is executed.

| * sh: Don't let SH-4A clobber SH-4 CFLAGS.Paul Mundt2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Older compilers don't support the -m4a{,nofpu} flags, which has the side-effect of allowing FP operations to be emitted. Switch this to incremental tuning, so we at least have -m4-nofpu as a fallback for the gcc3 toolchains. Without this, certain modules emit references to __udivsi3_i4 and __sdivsi3_i4.

| * sh: Drop -Wa,-dsp for DSP tuning.Paul Mundt2007-07-06
| | | | | | | | | | | | | | | | | | We already hand off the proper ISA variant with the dsp specifier appended, so we don't need to explicitly set -dsp. This causes some confusion with certain toolchains that are restricted to -dsp family opcodes artificially. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Correct __xdiv64_32/div64_32 return value size.Paul Mundt2007-07-05
| | | | | | | | | | | | | | | | | | These should be returning a uint32_t, whereas they were erroneously returning a u64 before. As the register sizes are 32-bits, this doesn't really make a lot of sense. Reported-by: Katsuya MATSUBARA <matsu@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: rework ipr codeMagnus Damm2007-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the ipr code by grouping the offset array together with the ipr_data structure in a new data structure called ipr_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. This strategy has much in common with the recently merged intc2 code. One logic change has been made - the original ipr code enabled the interrupts by default but with this patch they are all disabled by default.

| * sh: Only support PMB for SH-X cores.Paul Mundt2007-06-15
| | | | | | | | | | | | | | We don't have a PMB for SH-X2 or later, so only enable it for the few CPUs that support it. Fixes up the boot for SH4AL-DSP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: rework intc2 codeMagnus Damm2007-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The shared intc2 code currently contains cpu-specific #ifdefs. This is a tad unclean and it prevents us from using the shared code to drive board-specific irqs on the se7780 board. This patch reworks the intc2 code by moving the base addresses of the intc2 registers into struct intc2_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks.
