2012-09-28Make most arch asm/module.h files use asm-generic/module.hDavid Howells
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.

2012-05-25microblaze: Do not select GENERIC_GPIO by defaultLars-Peter Clausen
The microblaze architecture does not provide a native GPIO API implementation nor requires GPIOLIB, but still selects GENERIC_GPIO by default. As a result the following build error occurs, if GPIOLIB is not selected: include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep': include/asm-generic/gpio.h:218: error: implicit declaration of function '__gpio_get_value' include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep': include/asm-generic/gpio.h:224: error: implicit declaration of function '__gpio_set_value' This patch addresses the issue by not selecting GENERIC_GPIO by default. This causes the GPIO API to be stubbed out if no implementation is provided. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: stable@vger.kernel.org Tested-by: Michal Simek <monstr@monstr.eu>
2012-05-21timers: Fixup the Kconfig consolidation falloutThomas Gleixner
Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

2010-12-29of/flattree: Add Kconfig for EARLY_FLATTREEStephen Neuendorffer
The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored.

2010-08-04microblaze: Add KGDB supportMichal Simek
Kgdb uses brki r16, 0x18 instruction to call low level _debug_exception function which save current state to pt_regs and call microblaze_kgdb_break function. _debug_exception should be called only from the kernel space. User space calling is not supported because user application debugging uses different handling. pt_regs_to_gdb_regs loads additional special registers which can't be changed * Enable KGDB in Kconfig * Remove ancient not-tested KGDB support * Remove ancient _debug_exception code from entry.S Only MMU KGDB support is supported.

2010-07-27time: Kill off CONFIG_GENERIC_TIMEJohn Stultz
Now that all arches have been converted over to use generic time via clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME config option and simplify the generic code.
