nios2: move generic-y of exported headers to uapi/asm/Kbuild

2017-07-11T12:33:43+00:00

Since commit fcc8487d477a ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.

To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.

With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.

Also, move "generic-y += kprobes.h" up in order to keep the entries
sorted.

nios2: remove unneeded arch/nios2/include/(generated/)asm/signal.h

2017-07-11T12:33:36+00:00

Currently, NIOS2 has three signal.h files under arch/nios2/include:

[1] arch/nios2/include/asm/signal.h
[2] arch/nios2/include/uapi/asm/signal.h
[3] arch/nios2/include/generated/asm/signal.h

[3] is build-time generated by scripts/Makefile.asm-generic.
However, -I$(srctree)/arch/$(hdr-arch)/include search path is listed
before -I$(objtree)/arch/$(hdr-arch)/include/generated in LINUXINCLUDE.
Therefore [1] is always included instead of [3].  Remove [3] which
is never included.

If we look at [1], it just includes [2].  So, [1] can be removed
as well.

arch: remove unused macro/function thread_saved_pc()

2017-06-28T23:13:57+00:00

The only user of thread_saved_pc() in non-arch-specific code was removed
in commit 8243d5597793 ("sched/core: Remove pointless printout in
sched_show_task()").  Remove the implementations as well.

Some architectures use thread_saved_pc() in their arch-specific code.
Leave their thread_saved_pc() intact.

signal: Remove non-uapi

2017-06-04T13:11:47+00:00

By moving the kernel side __SI_* defintions right next to the userspace
ones we can kill the non-uapi versions of  include
include/asm-generic/siginfo.h and untangle the unholy mess of includes.

nios2: remove custom early console implementation

2017-05-11T09:44:21+00:00

As of commits d8f347ba35cf ("nios2: enable earlycon support"),
0dcc0542a006 ("serial: altera_jtaguart: add earlycon support") and
4d9d7d896d77 ("serial: altera_uart: add earlycon support"), the nios2
architecture and the altera_uart/altera_jtaguart drivers support
earlycon. Thus, the custom early console implementation for nios2 is no
longer necessary to get early boot messages. Remove it and rely fully on
earlycon support.
