The IRQ_PER_CPU Kconfig symbol was removed in the following commit: Commit 6a58fb3b ("genirq: Remove CONFIG_IRQ_PER_CPU") merged in v2.6.39-rc1. But IRQ_PER_CPU wasn't removed from any of the architecture Kconfig files where it was defined or selected. It's completely unused so remove the remaining references.

Manuel Lauss <manuel.lauss@gmail.com> writes: I introduced it as a fallback because early revisions of Alchemy hardware we shipped had a non-functional 32kHz timer and had to rely on the r4k timer instead. Previously the r4k timer was initialized regardless, but it's useless with the "wait" instruction. So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols. Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

With the upcoming merge of the ARC architecture there is a small likelyhood of conflicting use for the CONFIG_ARC config symbol. Rename it to CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64 to CONFIG_FW_ARC64. For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and CONFIG_CFE to CONFIG_FW_CFE.

Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.
