* Blackfin: unify core IRQ definitionsMike Frysinger2011-05-258-379/+64
| | | | | | | Start a new common IRQ header and move all of the CEC pieces there. This lets the individual part headers worry just about its SIC defines. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: ints-priority: unify duplicate vec to irq lookup logicMike Frysinger2011-05-251-68/+44
| | | | | | | | Seems the ipipe code just copied & pasted the existing irq lookup logic, so pull the logic out of do_irq() and into a local helper, and convert the two users over to that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: ints-priority: clean up some local varsMike Frysinger2011-05-251-17/+8
| | | | | | | | The local ivg structs need not be exported, so mark them as static. Further, the "num_spurious" variable is only incremented and never actually read anywhere, so punt it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: don't attempt to flush on-chip L1 SRAM regionsSonic Zhang2011-05-251-5/+18
| | | | | | | | | Since the on-chip L1 regions are not cacheable, there is no point in trying to flush/invalidate them. Plus, older Blackfin parts like to trigger an exception (like BF533-0.3). Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * percpu: Always align percpu output section to PAGE_SIZETejun Heo2011-03-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Percpu allocator honors alignment request upto PAGE_SIZE and both the percpu addresses in the percpu address space and the translated kernel addresses should be aligned accordingly. The calculation of the former depends on the alignment of percpu output section in the kernel image. The linker script macros PERCPU_VADDR() and PERCPU() are used to define this output section and the latter takes @align parameter. Several architectures are using @align smaller than PAGE_SIZE breaking percpu memory alignment. This patch removes @align parameter from PERCPU(), renames it to PERCPU_SECTION() and makes it always align to PAGE_SIZE. While at it, add PCPU_SETUP_BUG_ON() checks such that alignment problems are reliably detected and remove percpu alignment comment recently added in workqueue.c as the condition would trigger BUG way before reaching there. For um, this patch raises the alignment of percpu area. As the area is in .init, there shouldn't be any noticeable difference. This problem was discovered by David Howells while debugging boot failure on mn10300.

* | | | | [CPUFREQ] use dynamic debug instead of custom infrastructureDominik Brodowski2011-05-041-3/+0

As a first step, remove the old cpufreq_debug_printk() function and replace it with a call to the generic pr_debug() function. How can dynamic debug be used on cpufreq? You need a kernel which has CONFIG_DYNAMIC_DEBUG enabled. To enabled debugging during runtime, mount debugfs and $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control for debugging the complete "cpufreq" module. To achieve the same goal during boot, append ddebug_query="module cpufreq +p" as a boot parameter to the kernel of your choice.

This is because the code uses the non-smp version of memory barriers (as well it should). The Blackfin smp barrier logic at the moment contains the cache sync logic, but the non-smp barriers do not. This is incorrect as Rafel summarized: > ... > The existing memory barriers are SMP barriers too, but they are more > than _just_ SMP barriers. At least that's how it is _supposed_ to be > (eg. rmb() is supposed to be stronger than smp_rmb()). > ... > However, looking at the blackfin's definitions of SMP barriers I see > that it uses extra stuff that should _also_ be used in the definitions > of the mandatory barriers. > ...

According to Thomas, the former is the correct direct conversion, but it does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c seems to initialize both to the same thing), and the chip data in some ways is the more logical. Somebody should really decide on one of the other. This merge picks irq_desc_get_handler_data() as the straightforward pure conversion to new names, as per Thomas.

Because byte order of inode and block bitmaps is different on each architecture like below: m68k: big-endian 16bit indexed bitmaps h8300, microblaze, s390, sparc, m68knommu: big-endian 32 or 64bit indexed bitmaps m32r, mips, sh, xtensa: big-endian 32 or 64bit indexed bitmaps for big-endian mode little-endian bitmaps for little-endian mode Others: little-endian bitmaps In order to move minix bit operations from asm/bitops.h to architecture independent code in minix filesystem, this provides two config options. CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k. CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu, m32r, mips, sh, xtensa). The architectures which always use little-endian bitmaps do not select these options. Finally, we can remove minix bit operations from asm/bitops.h for all architectures.

* | | bitops: remove ext2 non-atomic bitops from asm/bitops.hAkinobu Mita2011-03-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the result of conversions, there are no users of ext2 non-atomic bit operations except for ext2 filesystem itself. Now we can put them into architecture independent code in ext2 filesystem, and remove from asm/bitops.h for all architectures.

(alpha, avr32, blackfin, cris, frv, h8300, ia64, m32r, mips, mn10300, parisc, sh, sparc, tile, x86, xtensa) These architectures can just include generic implementation (asm-generic/bitops/le.h).

* | Blackfin: punt unused HDMA masksMike Frysinger2011-03-185-93/+0
| | | | | | | | | | | | | | | | | | No code uses these, and the short define names are polluting the global namespace where they collide with things like common irq files. So just punt the damned things. If in the future we need HDMA support, we can make a standalone header for these things. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* | Blackfin/ipipe: fix deferred pipeline sync for the root stagePhilippe Gerum2011-03-182-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes sure to sync the pipeline for the root stage only from the outer interrupt level, when resuming kernel code after an interrupt. This fixes a bug causing EVT15 to be spuriously popped off upon nested interrupts, which in turn would cause the preempted kernel code to resume without supervisor privileges.
