kconfig: include kernel/Kconfig.preempt from init/Kconfig

2018-08-01T23:06:54+00:00

Almost all architectures include it.  Add a ARCH_NO_PREEMPT symbol to
disable preempt support for alpha, hexagon, non-coldfire m68k and
user mode Linux.

Kconfig: consolidate the "Kernel hacking" menu

2018-08-01T23:06:48+00:00

Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to
the top-level Kconfig.  For two architectures that means moving their
arch-specific symbols in that menu into a new arch Kconfig.debug file,
and for a few more creating a dummy file so that we can include it
unconditionally.

Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where
it belongs.

kconfig: include common Kconfig files from top-level Kconfig

2018-08-01T23:03:23+00:00

Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.

Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of
the top-level Kconfig into arch/Kconfig so that don't violate ordering
constraits while keeping a sensible menu structure.

kconfig: remove duplicate SWAP symbol defintions

2018-08-01T23:03:23+00:00

microblaze and nios2 define their own always n SWAP symbols.  Remove those
and let the generic defintion do the right thing by adding a new symbol
to disable swap entirely.

microblaze: use generic dma_noncoherent_ops

2018-07-20T12:29:47+00:00

Switch to the generic noncoherent direct mapping implementation.

This removes the direction-based optimizations in
sync_{single,sg}_for_{cpu,device} which were marked untestested and
do not match the usually very well tested {un,}map_{single,sg}
implementations.

dma-debug: remove CONFIG_HAVE_DMA_API_DEBUG

2018-05-08T11:03:43+00:00

There is no arch specific code required for dma-debug, so there is no
need to opt into the support either.

microblaze: switch to NO_BOOTMEM

2018-03-16T11:51:27+00:00

Microblaze doesn't set CONFIG_NO_BOOTMEM and so memblock_virt_alloc()
doesn't work for CONFIG_HAVE_MEMBLOCK && !CONFIG_NO_BOOTMEM.

Similar change was already done by others architectures

arch: change default endian for microblaze

2017-09-25T13:31:26+00:00

Fix the default for microblaze. Michal Simek mentioned default for
microblaze should be CPU_LITTLE_ENDIAN.

arch/microblaze: add choice for endianness and update Makefile

2017-09-09T01:26:48+00:00

microblaze architectures can be configured for either little or big endian
formats.  Add a choice option for the user to select the correct endian
format(default to big endian).

Also update the Makefile so toolchain can compile for the format it is
configured for.
