MIPS: Fix KVM guest fixmap address

2015-06-21T19:53:54+00:00

KVM guest kernels for trap & emulate run in user mode, with a modified
set of kernel memory segments. However the fixmap address is still in
the normal KSeg3 region at 0xfffe0000 regardless, causing problems when
cache alias handling makes use of them when handling copy on write.

Therefore define FIXADDR_TOP as 0x7ffe0000 in the guest kernel mapped
region when CONFIG_KVM_GUEST is defined.

MIPS/IRQCHIP: Move irq_chip from arch/mips to drivers/irqchip.

2015-06-21T19:52:50+00:00

While at it, rename it because in drivers/irqchip no longer every CPU is
a MIPS.

MIPS: DMA: Allow platforms to override only the post DMA hook

2015-04-08T21:52:33+00:00

Instead of having platforms to copy the entirety of
mach-generic/dma-coherence.h, check whether these platforms have already
defined a plat_post_dma_flush hook, and if not, provide an inline stub.

MIPS: Create a common

2015-03-31T09:59:40+00:00

11 platforms require at least one of these workarounds to be enabled; 22
platforms do not.  In the latter case we can fall back to a generic version.

Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.

mips: delete non-required instances of include

2014-01-24T21:39:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

mips/ide: flush dcache also if icache does not snoop dcache

2014-01-24T21:39:56+00:00

If this is not done then the new just read data which remains in dcache
will not make it into icache on time. Thus the CPU loads invalid data
and executes crap. The result is that the user is not able to execute
anything from its IDE based media while reading plain data is still
working well.

MIPS: improve checks for noncoherent DMA

2014-01-22T19:43:10+00:00

Only one MIPS development board actually supports enabling/disabling DMA
coherency at runtime, so it's not a good idea to push the overhead of
checking that configuration setting onto every other supported target as
well.
