clocksources: Switch back to the clksrc table

2016-06-28T08:19:35+00:00

All the clocksource drivers's init function are now converted to return
an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
clksrc-of table.

Let's convert back the names:
 - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
 - clksrc-of-ret              => clksrc-of

clocksource/drivers/nios2: Convert init function to return error

2016-06-28T08:19:34+00:00

The init functions do not return any error. They behave as the following:

  - panic, thus leading to a kernel crash while another timer may work and
       make the system boot up correctly

  or

  - print an error and let the caller unaware if the state of the system

Change that by converting the init functions to return an error conforming
to the CLOCKSOURCE_OF_RET prototype.

Proper error handling (rollback, errno value) will be changed later case
by case, thus this change just return back an error or success in the init
function.

nios2: Replace fdt_translate_address with of_flat_dt_translate_address

2016-03-31T00:15:45+00:00

nios2 builds fail with the following build error.

arch/nios2/kernel/prom.c: In function 'early_init_dt_scan_serial':
arch/nios2/kernel/prom.c:100:2: error:
	implicit declaration of function 'fdt_translate_address'

Commit c90fe9c0394b ("of: earlycon: Move address translation to
of_setup_earlycon()") replaced fdt_translate_address() with
of_flat_dt_translate_address() but missed updating the nios2 code.

arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections

2016-03-25T23:37:42+00:00

KASAN needs to know whether the allocation happens in an IRQ handler.
This lets us strip everything below the IRQ entry point to reduce the
number of unique stack traces needed to be stored.

Move the definition of __irq_entry to  so that the
users don't need to pull in .  Also introduce the
__softirq_entry macro which is similar to __irq_entry, but puts the
corresponding functions to the .softirqentry.text section.

nios2: Fix unused variable warning

2015-11-09T02:33:29+00:00

Fix the following compiler splat by adding __maybe_unused annotation to
the variable. Using this particular annotation has the least ugly impact
on the code compared to using ifdeffery.

arch/nios2/kernel/setup.c: In function 'nios2_boot_init':

clocksource: cosmetic: Drop OF 'dependency' from symbols

2015-10-01T00:18:39+00:00

Seeing the 'of' characters in a symbol that is being called from
ACPI seems to freak out people. So let's do a bit of pointless
renaming so that these folks do feel at home.

nios2/time: Migrate to new 'set-state' interface

2015-09-07T17:30:30+00:00

Migrate nios2 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now.

This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.
