MIPS: Rename the "Fill" cache ops to avoid build failure

2020-04-26T13:40:50+00:00

MIPS define a "Fill" macro as a cache operation in cacheops.h, this
will cause build failure under some special configurations because in
seq_file.c there is a "Fill" label. To avoid this failure we rename the
"Fill" macro to "Fill_I" which has the same coding style as other cache
operations in cacheops.h (we think renaming the "Fill" macro is more
reasonable than renaming the "Fill" label).

Callers of "Fill" macro is also updated.

MIPS: pass non-NULL dev_id on shared request_irq()

2020-03-16T15:04:49+00:00

Recently all usages of setup_irq() was replaced by request_irq().
request_irq() does a few sanity checks that were not done in
setup_irq(), if they fail irq registration will fail. One of the check
is to ensure that non-NULL dev_id is passed in the case of shared irq.
This caused malta on qemu to hang.

Fix it by passing handler as dev_id to all request_irq()'s that are
shared. For sni, instead of passing non-NULL dev_id, remove shared irq
flags.

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35+00:00

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.

Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.

Hence replace setup_irq() by request_irq().

remove_irq() has been replaced by free_irq() as well.

There were build error's during previous version, couple of which was
reported by kbuild test robot  of which one was reported
by Thomas Bogendoerfer  as well. There were a
few more issues including build errors, those also have been fixed.

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

MIPS: pmcs-msp71xx: Remove unused addr variable

2019-10-03T22:47:17+00:00

The addr variable in prom_free_prom_memory() has been unused since
commit b3c948e2c00f ("MIPS: msp: Record prom memory"), causing a warning
& build failure due to -Werror. Remove the unused variable.

MIPS: pmcs-msp71xx: Add missing MAX_PROM_MEM definition

2019-10-03T22:47:14+00:00

Commit b3c948e2c00f ("MIPS: msp: Record prom memory") introduced use of
a MAX_PROM_MEM value but didn't define it. A bounds check in
prom_meminit() suggests its value was supposed to be 5, so define it as
such & adjust the bounds check to use the macro rather than a magic
number.
