Drop extern for all prototypes and adjust alignment of parameters
as required after the removal.
In a few rare cases adjust linelength to conform to maximum 80 chars,
and likewise in a few rare cases adjust alignment of parameters
to static functions.

sparc: Fix user_addr_max() definition.2012-05-24T20:41:58+00:00David S. Millerdavem@davemloft.net2012-05-24T20:41:58+00:00urn:sha1:c5389831cda3b38a56606a348a537a1332f2d729
We need to use TASK_SIZE because for 64-bit tasks the value
of STACK_TOP actually sits in the middle of the address space
so we'll get false-negatives.
Adjust the TASK_SIZE definition on sparc64 to accomodate this,
in the context in which user_addr_max() is used we have the
test_thread_flag() definition available but not the one for
test_tsk_thread_flag().

sparc: Increase portability of strncpy_from_user() implementation.2012-05-24T20:04:24+00:00David S. Millerdavem@davemloft.net2012-05-24T02:56:06+00:00urn:sha1:35c9646062eba15351c6d64ea0c02176e5cb66ac
Hide details of maximum user address calculation in a new
asm/uaccess.h interface named user_addr_max().
Provide little-endian implementation in find_zero(), which should work
but can probably be improved.
Abstrace alignment check behind IS_UNALIGNED() macro.
Kill double-semicolon, noticed by David Howells.

sparc: Add full proper error handling to strncpy_from_user().2012-05-23T06:32:27+00:00David S. Millerdavem@davemloft.net2012-05-23T00:53:19+00:00urn:sha1:ff06dffbc8abfc60d6a0332f058f1d1bb01abb31
Linus removed the end-of-address-space hackery from
fs/namei.c:do_getname() so we really have to validate these edge
conditions and cannot cheat any more (as x86 used to as well).
Move to a common C implementation like x86 did. And if both
src and dst are sufficiently aligned we'll do word at a time
copies and checks as well.

sparc, sparc64: use arch/sparc/include2008-07-27T21:00:59+00:00Sam Ravnborgsam@ravnborg.org2008-07-27T21:00:59+00:00urn:sha1:a439fe51a1f8eb087c22dd24d69cebae4a3addac
The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***
The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
