types: add C99-style constructors to

2008-05-02T23:18:42+00:00

Add C99-style constructor macros for fixed types to
.  Since Linux uses names like "u64" instead of
"uint64_t", the constructor macros are called U64_C() instead of
UINT64_C() and so forth.

These macros allow specific sizes to be specified as
U64_C(0x123456789abcdef), without gcc issuing warnings as it will if
one writes (u64)0x123456789abcdef.

When used from assembly, these macros pass their argument unchanged.

types: create

2008-05-02T23:18:19+00:00

This creates two generic files with common integer definitions; one
where 64 bits is "long" (most 64-bit architectures) and one where 64
bits is "long long" (all 32-bit architectures and x86-64.)

rename div64_64 to div64_u64

2008-05-01T15:03:58+00:00

Rename div64_64 to div64_u64 to make it consistent with the other divide
functions, so it clearly includes the type of the divide.  Move its definition
to math64.h as currently no architecture overrides the generic implementation.
 They can still override it of course, but the duplicated declarations are
avoided.

asm-*/futex.h should include linux/uaccess.h

2008-04-30T15:29:52+00:00

Lots of asm-*/futex.h call pagefault_enable and pagefault_disable, which
are declared in linux/uaccess.h, without including linux/uaccess.h.

They all include asm/uaccess.h, so this patch replaces asm/uaccess.h
with linux/uaccess.h.

kernel: Move arches to use common unaligned access

2008-04-29T15:06:27+00:00

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.

generalize asm-generic/ioctl.h to allow overriding values

2008-04-29T15:06:24+00:00

In the spirit of a number of other asm-generic header files,
generalize asm-generic/ioctl.h to allow arch-specific ioctl.h headers
to simply override _IOC_SIZEBITS and/or _IOC_DIRBITS before including
this header file, allowing a number of ioctl.h header files to be
shortened considerably.

gpiochip_reserve()

2008-04-28T15:58:34+00:00

Add a new function gpiochip_reserve() to reserve ranges of gpios that platform
code has pre-allocated.  That is, this marks gpio numbers which will be
claimed by drivers that haven't yet been loaded, and thus are not available
for dynamic gpio number allocation.
