2012-04-26blackfin: fix ifdef fustercluck in mach-bf538/boards/ezkit.cPaul Gortmaker
This file has lots and lots of ifdef, around structure decls and structure usages. The failure issue was that we would build the BF538-EZKIT_defconfig and get: arch/blackfin/mach-bf538/boards/ezkit.c:924:3: error: 'bfin_lq035q1_device' undeclared here (not in a function) even though the same ifdef _appeared_ to enable both the struct declaration and the code that used it. Yet cpp was telling us we didn't have the struct, but we still had the usage of it. However, _appeared_ is the operative word. After marking all the anonymous #endif with their parent #ifdef config options, it was _then_ clear that there was a misplaced #endif that was hiding the struct declaration. The real guts of the patch boils down to this: -#endif +#endif /* CONFIG_MTD_M25P80 */ +#endif /* CONFIG_SPI_BFIN5XX */ [...] -#endif /* spi master and devices */ but since I had to tag the #endif with their respective #ifdef options to find this misplaced SPI endif, it would be silly to then go and delete them all. So they stay. Cc: Sonic Zhang <sonic.zhang@analog.com> Cc: Bob Liu <lliubbo@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...
