MIPS: iomap: Use __mem_{read,write}{b,w,l} for MMIO
Using the __raw_{read,write}{b,w,l} functions to perform
repeatable MMIO could result in problems if the host bus
does not match the endianness of the PCI/ISA. This problem
is visible on big-endian SEAD3 configurations after commit
2925f6c0c7af32720dcbadc586463aeceb6baa22
"net: smc911x: use io{read,write}*_rep accessors". This effectively
moves away from using the __mem_* variants to __raw_* ones

MIPS: Apply `.insn' to fixup labels throughout
Fix the issue with the ISA bit being lost in fixups that jump to labels
placed just before a section switch. Such a switch leads to the ISA bit
being lost, because GAS concludes there is no code that follows and
therefore the label refers to data. Use the `.insn' pseudo-op to
convince the tool this is not the case.
This lack of label annotation leads to microMIPS compilation errors
like:

MIPS: Fix microMIPS LL/SC immediate offsets
In the microMIPS encoding some memory access instructions have their
immediate offset reduced to 12 bits only. That does not match the GCC
`R' constraint we use in some places to satisfy the requirement,
resulting in build failures like this:
{standard input}: Assembler messages:
{standard input}:720: Error: macro used $at after ".set noat"
{standard input}:720: Warning: macro instruction expanded into multiple instructions
Fix the problem by defining a macro, `GCC_OFF12_ASM', that expands to
the right constraint depending on whether microMIPS or standard MIPS
code is produced. Also apply the fix to where `m' is used as in the
worst case this change does nothing, e.g. where the pointer was already
in a register such as a function argument and no further offset was
requested, and in the best case it avoids an extraneous sequence of up
to two instructions to load the high 20 bits of the address in the LL/SC
loop. This reduces the risk of lock contention that is the higher the
more instructions there are in the critical section between LL and SC.
Strictly speaking we could just bulk-replace `R' with `ZC' as the latter
constraint adjusts automatically depending on the ISA selected.
However it was only introduced with GCC 4.9 and we keep supporing older
compilers for the standard MIPS configuration, hence the slightly more
complicated approach I chose.
The choice of a zero-argument function-like rather than an object-like
macro was made so that it does not look like a function call taking the
C expression used for the constraint as an argument. This is so as not
to confuse the reader or formatting checkers like `checkpatch.pl' and
follows previous practice.

are lacking too, e.g. GCC produces bad code:

And our build fails early on, so disable the configuration, for the sake
of automatic random config checkers if nothing else. Whoever needs to

The microMIPS microassembler is only suitable for configurations where
the kernel itself is built to microMIPS machine code and not where only
user microMIPS software is supported. The former is controlled with the

used for the latter.
Not only that, but with a given microMIPS vs standard MIPS kernel
configuration only one microassembler is needed, that matches the ISA

so there is never a need to mix microMIPS and standard MIPS code.

MIPS: Kconfig: Enable microMIPS support for Malta
Add missing microMIPS support to Malta. Currently the kernel only
enables support for the instruction set for the SEAD-3 board despite the
fact processor features have nothing to do with the board a processor is

In this case there is no way to run microMIPS software in a fully
supported way under Linux on QEMU. QEMU supports the emulation of a
Malta board, but does not emulate SEAD-3. Linux supports running
microMIPS code on a SEAD-3 board, but hardcodes such support to off on
an emulated Malta board even if the processor selected has the microMIPS
instruction set implemented.
Adding support for the SEAD-3 to QEMU is a major project. Flipping a
bit in the kernel that shouldn't have been cleared in the first place is
a trivial effort. Thus the answer is plain...
