MIPS: Export memcpy & memset functions alongside their definitions

2017-01-03T15:34:50+00:00

Now that EXPORT_SYMBOL can be used from assembly source, move the
EXPORT_SYMBOL invocations for the memcpy & memset functions & variants
thereof to be alongside their definitions.

MIPS: uaccess: Take EVA into account in [__]clear_user

2015-12-22T10:58:43+00:00

__clear_user() (and clear_user() which uses it), always access the user
mode address space, which results in EVA store instructions when EVA is
enabled even if the current user address limit is KERNEL_DS.

Fix this by adding a new symbol __bzero_kernel for the normal kernel
address space bzero in EVA mode, and call that from __clear_user() if
eva_kernel_access().

MIPS: lib: memset: Add MIPS R6 support

2015-02-17T15:37:30+00:00

MIPS R6 dropped the unaligned load and store instructions so
we need to re-write this part of the code for R6 to store
one byte at a time.

MIPS: lib: memset: Clean up some MIPS{EL,EB} ifdefery

2014-11-24T06:45:42+00:00

The toolchain defines exactly one of __MIPSEB__ and
__MIPSEL__. As a result, simplify the ifdefery a little bit.

MIPS: lib: memset: Add EVA support for the __bzero function.

2014-03-26T22:09:15+00:00

Build the __bzero function using the EVA load/store instructions
when operating in the EVA mode. This function is only used when
accessing user code so there is no need to build two distinct symbols
for user and kernel operations respectively.

MIPS: lib: memset: Use macro to build the __bzero symbol

2014-03-26T22:09:15+00:00

Build the __bzero symbol using a macor. In EVA mode we will
need to use similar code to do the userspace load operations so
it is better if we use a macro to avoid code duplications.

MIPS: microMIPS: Optimise 'memset' core library function.

2013-05-09T15:55:19+00:00

Optimise 'memset' to use microMIPS instructions and/or optimisations
for binary size reduction. When the microMIPS ISA is not being used,
the library function compiles to the original binary code.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.
