[MIPS] R1: Fix hazard barriers to make kernels work on R2 also.
Tested with Malta; inflates malta_defconfig by 3932 bytes. Ideally there
should be additional configuration to allow getting rid of this overhead
but that would be too much complexity at this stage of the release cycle.

[MIPS] VPE: reimplement ELF loader.
Loading ELF binaries based on the section table is totally wrong. This
still leaves the other fat bug of referencing symbols in an executable
unfixed, so people better don't run strip on their binaries ...
As added bonus the new loader is also 23 lines shorter.
On MP configurations it's highly dubious what this code will actually
affect since blasting away cachelines may or may not do the right
thing wrt. cache coherency.
[MIPS] Don't abort the build process if '-msym32' isn't supported
-msym32 and previously the strategy to tell the compiler to generate
64-bit code but the assembler to put it into 32-bit ELF was initially
a hack to get around the lack of proper 64-bit binutils support and
later turned into a neat optimization with significant code size
savings. But it's really just an optimization so there is nothing
wrong with just dropping the option (and whatever else goes along with
it, I forgot all the nasty details) on the floor if due to a vintage
compiler it can't be suported.

[MIPS] Dyntick support for SMTC:
The kernel currently only supports broadcasting of the timer interrupt
from a single timer, not multicasting into two multicast groups of
processors. So the implemented mechanism for SMTC works by broadcasting
the cp0 compare interrupt on VPE 0 and ignoring it on any additional VPEs.

[MIPS] Switch from to_tm to rtc_time_to_tm
This replaces the MIPS-specific to_tm function with the generic
rtc_time_to_tm function. The big difference between the two functions is
that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of
rtc_time_to_tm needs to be fixed up.

[MIPS] Split up war.h
It was getting a little big, ugly and a primary source for merge conflicts.
Also the old method was a bit too forgiving in that the workaround did
default to off, so now there is an explicit #error forcing platform
maintainers to think if they should enable a workaround for a particular
platform.
Add CFE support to the BCM47XX code. That includes querying CFE environment
variables as well as using CFE to print messages before the serial port is
initialized (early printk).

It may not be perfect yet but the SB1 code is badly borken and has

[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32
This patch renames it for 3 reasons:
- "CONFIG" pattern is used by Kconfig. Now this macro is
no more defined by Kconfig but by Kbuild itself make this
clear by translating "CONFIG" into "KBUILD".
- "ELF32" word is improper because it is irrelevant to ELF
format and it makes confusion with CONFIG_BOOT_ELF32. So
translate it with SYM32.
- Add "64BIT" part to make clear that this macro implies a
64 bits kernel.

[MIPS] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64
This patch removes '-mno-explicit-relocs' usage when
CONFIG_BUILD_ELF64 is set since this option was only required
with the old hack to truncate addresses at the assembly level
where "-mabi=64 -Wa,-mabi=32" was used.
This should yield a small code size improvement for inline
assembly, where the R constraint is used.
The idea is coming from Maciej <macro@linux-mips.org>.
ide: use only ->set_pio_mode method for programming PIO modes (take 2)
Use ->set_pio_mode method to program PIO modes in ide_set_xfer_rate()
(the only place which used ->speedproc to program PIO modes) and remove
handling of PIO modes from all ->speedproc implementations.
v2:
* Fix pmac_ide_tune_chipset() comment.
There should be no functionality changes caused by this patch.
* Return failure in ->speedproc method for unsupported/invalid transfer
modes passed from user-space (fixes theoretical OOPS in ali_tune_pio()
and/or setting random PIO timings on host controller + disabling UDMA
bit + setting unsupported/invalid transfer mode on the device).
* Don't disable UDMA bit when programming PIO modes.
* Add FIXME about DMA timings never being set.
* Bump driver version.

siimage: fix ->set_pio_mode method to select PIO data transfer
* Remember to select PIO data transfer (with IORDY monitored) in sil_tune_pio()
(->set_pio_mode method) so the controller is always programmed correctly for
PIO transfers (this is important if DMA is not going to be used).
* Don't set DMA/UDMA timings for PIO modes in siimage_tune_chipset().
* Bump driver version.

* Add { 0, 0 } entry to {kauai,shasta}_pio_timings[] so kauai_lookup_timing()
always returns a valid PIO timing (fixes PIO timing not being set for devices
with minimum PIO cycle <= 120ns).
* Add setting transfer mode on the device to pmac_ide_set_pio_mode().
* Fix pmac_ide_set_pio() to always program chipset for given PIO timing instead
of only when the device we want to program PIO timing for is the currently
selected one.
* Now that pmac_ide_set_pio() is fixed there is no need to set transfer mode
on the device and program chipset for PIO in pmac_ide_tune_chipset()
(returning 0 == success is not entirely correct but is OK for now since
the upper layers are only checking ->speedproc return value for DMA modes).
v2:
* s/speed/XFER_PIO_0 + pio/ in pmac_ide_set_pio_mode() so it actually compiles.
* Removal of kauai_lookup_timing() return value checking went to separate patch.
v3:
* Use XFER_PIO_0 not XFER_PIO. (Noticed by Ben)

icside: fix ->speedproc to return on unsupported modes (take 5)
* All other implementations of ->speedproc return zero on success
and non-zero on failure. Currently it doesn't matter for icside host
driver and isn't a bug per se since:
- ide_set_xfer_rate() return value is ignored by all IDE core users
- icside doesn't (yet!) use ide_tune_dma() in icside_dma_check()
but sooner or later we will need to fix anyway - so lets do it now.
* icside_set_speed() happily accepts unsupported transfer modes which
results in drive->drive_data being set to the maximum value (480)
and drive->current_speed being set to the unsupported transfer mode.
Fix it.
v2:
* The initial version of the patch was broken because it didn't take into
the account (the different from usual) return values of icside_set_speed()
(Noticed by Russell).
v3:
* Remove no longer needed initialization/checking of cycle_time
(Noticed by Sergei).
* No need to set drive->drive_data if DMA is not going to be used
(Noticed by Sergei).
* Remove incorrect setting of drive->current_speed
(Noticed by Sergei).
* Move ide_config_drive_speed() at the end of icside_set_speed().
v4:
* If DMA mode is not found in icside_dma_check() then just return "-1" and
don't call icside_set_speed() (v3 got it wrong and "1" was returned instead).
v5:
* Return "-1"/"0" in icside_set_speed() instead of icside_dma_check() return
value (just like it was before this patch).

* Fix ide_dma_sgiioc4() to return success/failure. Check return value in
sgiioc4_ide_setup_pci_device() and set hwif->autodma accordingly. Also add
missing setting of drive->autodma.
* Add sgiioc4_speedproc() (implementation of ->speedproc method).
* Fix ->mwdma_mask (MWDMA2 mask is 0x04 not 0x02) and remove incorrect
->swdma_mask. Also remove needless initialization of ->ultra_mask.
* Use ide_tune_dma() in sgiioc4_ide_dma_check(), this fixes following bugs:

- DMA blacklist not being checked
- MWDMA2 mode support by device not being checked
