| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under arch/sparc during a 64-bit defconfig build. They fall into two categorites: 1) of_device_id is marked as __initdata, and we can never do this since these objects sit in the device core data structures way past boot. So even if a driver will never be reloaded, we have to keep the device ID table around. Mark such cases const instead. 2) The bootmem alloc/free handling code in mdesc.c was not fully marked __init as it should be, thus generating a reference to free_bootmem_late() (which is __init) from non-__init code.

* sparc: Use the new genirq functionalityThomas Gleixner2011-03-292-24/+9
| | | | | | | | | | | | | | | | Make use of the new features in genirq: 1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the core code that irq_eoi() is only called when the interrupt was handled. That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: sparclinux@vger.kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the preparation for testing the recent changes made to the SUN4D specific code in the kernel by Sam Ravnborg the following was discovered: Since the removal of of_platform_bus_type (commit: eca3930163ba8884060ce9d9ff5ef0d9b7c7b00f ) multiboard SUN4Ds have not been able to boot. The kernel crashes due to a zero-pointer error encountered when registering multiple M48T59 RTCs (There is one on each board). A patch for the was previously submitted, but the problem was not a serious at that time, as it would only generate warnings. Now the kernel will crash and stop executing before the serial console has been started.

* | lib, arch: add filter argument to show_mem and fix private implementationsDavid Rientjes2011-03-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which resulted in build warnings on all architectures that implement their own versions of show_mem(): lib/lib.a(show_mem.o): In function `show_mem': show_mem.c:(.text+0x1f4): multiple definition of `show_mem' arch/sparc/mm/built-in.o:(.text+0xd70): first defined here The fix is to remove __show_mem() and add its argument to show_mem() in all implementations to prevent this breakage. Architectures that implement their own show_mem() actually don't do anything with the argument yet, but they could be made to filter nodes that aren't allowed in the current context in the future just like the generic implementation.

* | bitops: remove minix bitops from asm/bitops.hAkinobu Mita2011-03-232-3/+0

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.

| * mm: make __get_user_pages return -EHWPOISON for HWPOISON page optionallyHuang Ying2011-03-171-0/+2

With this patch, the interested callers can distinguish HWPOISON pages from general FAULT pages, while other callers will still get -EFAULT for all these pages, so the user space interface need not to be changed. This feature is needed by KVM, where UCR MCE should be relayed to guest for HWPOISON page, while instruction emulation and MMIO will be tried for general FAULT page.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent patch to the x86 randomization code caused me to take a quick look at what we do on sparc64, and in doing so I noticed that we sometimes calculate a non-page-aligned randomization value and stick it into mmap_base. I also noticed that since I copied the logic over from PowerPC, the powerpc code has tweaked the randomization ranges in ways that would benefit us as well. For one thing, we should allow up to at least 8MB of randomization otherwise huge-page regions when HPAGE_SIZE is 4MB never randomize at all. And on the 64-bit side we were using up to 4GB. Tone it down to 1GB as 4GB can result in a lot of address space wastage. Finally, make sure all computations are unsigned. Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc32,sun4c: irq file cleanupSam Ravnborg2011-03-161-37/+44
| | | | | | | | | | | | | | | | | | | | | | | | - drop filename in header - drop unused includes - add description of sun4c interrupts (from davem) - add spaces after reserved words This is partly based on a patch from: David Miller <davem@davemloft.net> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* | sparc32: add irq + smp declarations to headersSam Ravnborg2011-03-165-13/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for cleaning up a number of files add declarations for irq and smp related data/functions to the relevant headers. This showed that the extern declaration of cputypval differed in the two files where it was used. As cputypval is defined like this: cputypval: .asciz "sun4c" the correct representation is a char array. Fix users to use the new declaration.

* | sparc32: remove tick14.cSam Ravnborg2011-03-163-44/+0
| | | | | | | | | | | | | | | | | | | | The two methods included in tick14.c was nop because the static variable linux_lvl14 was always NULL. So remove the file and callers. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* | SPARC/LEON: power down instruction different of different LEONsDaniel Hellstrom2011-03-165-17/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way a LEON is powered down is implemented differently depending on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB and CHIP. This is for example needed by the GR-LEON4-ITX board and the UT699. Previously the power down support for LEON was limited to SMP, now both SMP and UP systems use the instruction.

* | sparc32: added U-Boot build target: uImageDaniel Hellstrom2011-03-163-1/+66
| | | | | | | | | | | | | | | | This is only for LEON as u-boot for SPARC only supports LEON. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc64: rename virt_irq => irq - IISam Ravnborg2011-03-167-53/+53
| | | | | | | | | | | | | | | | | | | | | | The generic irq support uses the term 'irq' for the allocated irq number. Fix it so sparc64 use the same term for an irq as the generic irq support does. For a naive reader this is less confusing. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc64: use up-to-data genirq functionsSam Ravnborg2011-03-162-59/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop all uses of deprecated genirq features. The irq_set_affinity() call got a third paramter 'force' which is unused. For now genirq does not use this paramter and it is ignored by sparc.
