2013-03-12Select VIRT_TO_BUS directly where neededStephen Rothwell1-1/+1
In commit 887cbce0adea ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS") I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where needed. I am not sure what I was thinking. Instead, just directly select VIRT_TO_BUS where it is needed. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The IRQ_PER_CPU Kconfig symbol was removed in the following commit: Commit 6a58fb3bad099076f36f0f30f44507bc3275cdb6 ("genirq: Remove CONFIG_IRQ_PER_CPU") merged in v2.6.39-rc1.

2012-09-28Make most arch asm/module.h files use asm-generic/module.hDavid Howells1-0/+2
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.

That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts.

2011-12-08memblock: Kill early_node_map[]Tejun Heo1-3/+0
Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP - there's no user of early_node_map[] left. Kill early_node_map[] and replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP. Also, relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h as page_alloc.c would no longer host an alternative implementation. This change is ultimately one to one mapping and shouldn't cause any observable difference; however, after the recent changes, there are some functions which now would fit memblock.c better than page_alloc.c and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK doesn't make much sense on some of them. Further cleanups for functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice. -v2: Fix compile bug introduced by mis-spelling CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in mmzone.h.

2011-08-03Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHGHuang Ying1-0/+1
cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

Create a dedicated folder for iommu drivers, and move the base iommu implementation over there. Grouping the various iommu drivers in a single location will help finding similar problems shared by different platforms, so they could be solved once, in the iommu framework, instead of solved differently (or duplicated) in each driver.

2010-09-27[IA64] Stop using the deprecated __do_IRQ() code pathTony Luck1-2/+4
Thomas Gleixner <tglx@linutronix.de> wrote: >__do_IRQ() has been deprecated after a two years migration phase in >commit 0e57aa1. Since then another 18 months have gone by ... Mostly trivial stuff for this. The only tricky part was realizing that the new handler_*_irq() paths do not use desc->chip->end(irq). Not a problem for the edge case as the ia64 iosapic routine for that was nop(). But the "level" case handled interrupt migration there. Just use a slightly modified version of the "end" routine as "unmask" for the level triggered case. Signed-off-by: Tony Luck <tony.luck@intel.com>
