Follow Al Viro's m68k change from l-k: i.e. tell modpost that entry point code (that has to be outside of .init.text for external reasons) is OK to refer to .init.* Shuts up some section mismatch warnings from modpost. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch updates the r2d board support in a few ways: - CPU_SUBTYPE_SH7751R is selected in the defconfig to play well with the r2d board Kconfig entry. Without this the defconfig results in no board enabled. - Enable EARLY_PRINTK. - Enable SH_STANDARD_BIOS - this works well for early printk on the r2d board. - Add "earlyprink=bios" to the cmdline for early serial port output by default. - CONFIG_SUBTYPE_SH7751R support is added to the sh-specific pci makefile.

Currently this has a prompt to allow users to change it. There's no reason to do this, and it has caused breakage and confusion in the past, so remove it entirely. We'll get rid of this when the whole driver is tidied for the driver model. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This gets the SH cpufreq working again. We follow the changes in the AVR32 implementation for wrapping in to the clock framework. CPUs that wish to use this are required to define rate rounding primitives in order to satisfy clk_round_rate(). This works well enough for the common case, though we should look at unifying this driver across all of the platforms that implement clock framework support in one capacity or another.

This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.

This patch improves intc group support, ie it makes it possible to group interrupts together and mask / unmask the entire group. This also works with priorities, so setting a priority for an entire group is also possible. This patch is needed to properly support certain processors such as the 7780. Fixes for NULL pointers in DECLARE_INTC_DESC() are also included. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch cleans up solution engine 7722 specific interrupt code. The main purpose is to replace the mux function with use of set_irq_chained_handler() and replace hard coded register poking code with set_irq_type().

This is the second version of the shared interrupt controller patch for the sh architecture, fixing up handling of intc_reg_fns[]. The three main advantages with this controller over the existing ones are: - Both priority (ipr) and bitmap (intc2) registers are supported - External pin sense configuration is supported, ie edge vs level triggered - CPU/Board specific code maps 1:1 with datasheet for easy verification This controller can easily coexist with the current IPR and INTC2 controllers, but the idea is that CPUs/Boards should be moved over to this controller over time so we have a single code base to maintain.

Slab destructors were no longer supported after Christoph's c59def9f change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

This patch completes Linus's wish that the fault return codes be made into bit flags, which I agree makes everything nicer.

The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by: NJeremy Fitzhardinge <jeremy@goop.org> Acked-by: NHaavard Skinnemoen <hskinnemoen@atmel.com> Cc: Andi Kleen <ak@suse.de> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Paul Mundt <lethal@linux-sh.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

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.

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.
