The mapsize optimizations which were moved from x86 to the generic code in commit 64970b68 increased the binary size on non x86 architectures. Looking into the real effects of the "optimizations" it turned out that they are not used in find_next_bit() and find_next_zero_bit(). The ones in find_first_bit() and find_first_zero_bit() are used in a couple of places but none of them is a real hot path. Remove the "optimizations" all together and call the library functions unconditionally. Boot-tested on x86 and compile tested on every cross compiler I have. Signed-off-by:

New version that does not preserve the marker. Arch maintainers indicate that the marker functionality is is not needed anymore. Note you may simplify the s390 asm-offsets.c code further if you use the OFFSET() macro instead of the DEFINE. See kbuild.h Signed-off-by:

s390 has a strange marker in DEFINE. Undefine the DEFINE from kbuild.h and define it the way s390 wants it to preserve things as they were. May be good if the arch maintainer could go over this and check if this workaround is really necessary. Signed-off-by:

The same definitions are used for the bounds logic and the asm-offsets.h generation by kbuild. Put them into include/linux/kbuild.h file. Also add a new feature COMMENT("text") which can be used to insert lines of ocmments into asm-offsets.h and bounds.h. Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: -

Use vmalloc() and memset() instead of kcalloc() to allocate a page* array when the array size is bigger than one page. This enables relayfs to support bigger relay buffers than 64MB on 4k-page system, 512MB on 16k-page system. [akpm@linux-foundation.org: cleanup] Signed-off-by:

Unaligned access is ok for the following arches: cris, m68k, mn10300, powerpc, s390, x86 Arches that use the memmove implementation for native endian, and the byteshifting for the opposite endianness. h8300, m32r, xtensa Packed struct for native endian, byteshifting for other endian: alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh m86knommu is generic_be for Coldfire, otherwise unaligned access is ok. frv, arm chooses endianness based on compiler settings, uses the byteshifting versions. Remove the unaligned trap handler from frv as it is now unused. v850 is le, uses the byteshifting versions for both be and le. Remove the now unused asm-generic implementation. Signed-off-by:

Create a linux/unaligned directory similar in spirit to the linux/byteorder folder to hold generic implementations collected from various arches. Currently there are five implementations: 1) packed_struct.h: C-struct based, from asm-generic/unaligned.h 2) le_byteshift.h: Open coded byte-swapping, heavily based on asm-arm 3) be_byteshift.h: Open coded byte-swapping, heavily based on asm-arm 4) memmove.h: taken from multiple implementations in tree 5) access_ok.h: taken from x86 and others, unaligned access is ok. All of the new implementations checks for sizes not equal to 1,2,4,8 and will fail to link. API additions: get_unaligned_{le16|le32|le64|be16|be32|be64}(p) which is meant to replace code of the form: le16_to_cpu(get_unaligned((__le16 *)p)); put_unaligned_{le16|le32|le64|be16|be32|be64}(val, pointer) which is meant to replace code of the form: put_unaligned(cpu_to_le16(val), (__le16 *)p); The headers that arches should include from their asm/unaligned.h: access_ok.h : Wrappers of the byteswapping functions in asm/byteorder Choose a particular implementation for little-endian access: le_byteshift.h le_memmove.h (arch must be LE) le_struct.h (arch must be LE) Choose a particular implementation for big-endian access: be_byteshift.h be_memmove.h (arch must be BE) be_struct.h (arch must be BE) After including as needed from the above, include unaligned/generic.h and define your arch's get/put_unaligned as (for LE): Signed-off-by:
