(Commit 7cb777a3 (mtd: add ARM pismo support) intended to add this, but seems only to have patched the Makefile without touching Kconfig or providing any code...) The following patch adds support for PISMO modules found on ARM Ltd development platforms. These are MTD modules, and can have a selection of SRAM, flash or DOC devices as described by an on-board I2C EEPROM. We support SRAM and NOR flash devices only by registering appropriate conventional MTD platform devices as children of the 'pismo' device. Signed-off-by:

crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic. Signed-off-by:

Although reporting of benign GART TLB errors is disabled in __mcheck_cpu_apply_quirks, those are still being logged, and, as a result, trip up amd64_edac.

Use bitmap library and kill some unused iommu helper functions. 1. s/iommu_area_free/bitmap_clear/ 2. s/iommu_area_reserve/bitmap_set/ 3. Use bitmap_find_next_zero_area instead of find_next_zero_area This cannot be simple substitution because find_next_zero_area doesn't check the last bit of the limit in bitmap 4. Remove iommu_area_free, iommu_area_reserve, and find_next_zero_area Signed-off-by:

This introduces new bitmap functions: bitmap_set: Set specified bit area bitmap_clear: Clear specified bit area bitmap_find_next_zero_area: Find free bit area These are mostly stolen from iommu helper. The differences are: - Use find_next_bit instead of doing test_bit for each bit - Rewrite bitmap_set and bitmap_clear Instead of setting or clearing for each bit. - Check the last bit of the limit iommu-helper doesn't want to find such area - The return value if there is no zero area find_next_zero_area in iommu helper: returns -1 bitmap_find_next_zero_area: return >= bitmap size Signed-off-by:

GRU Message queue instructions are used to deliver messages to other SSIs within the numalink domain. In most cases, a single GRU mesq instruction will deliver both the message AND an interrupt to notify the other SSI that a messsage is present. In some cases, however, the interrupt must be sent explicitly. To improve resilency, the GRU driver should send these explicit interrupts using the GRU to write the remote chipset register. Current code sends the interrupt using a cpu instruction to write the chipset register. Signed-off-by:
