stat_timer only ever assigns the same function and data, so consolidate
to using timer_setup(), adjust callback, drop everything else used
to pass things around, and remove needless typedefs.
reset_timer is unused; remove it.

https://git.linaro.org/people/john.stultz/linux into timers/core
Pull timekeeping updates from John Stultz:
- More y2038 work from Arnd Bergmann
- A new mechanism to allow RTC drivers to specify the resolution of the
RTC so the suspend/resume code can make informed decisions whether to
inject the suspended time or not in case of fast suspend/resume cycles.

ntp is currently hardwired to try and call the rtc set when wall clock
tv_nsec is 0.5 seconds. This historical behaviour works well with certain
PC RTCs, but is not universal to all rtc hardware.
Change how this works by introducing the driver specific concept of
set_offset_nsec, the delay between current wall clock time and the target
time to set (with a 0 tv_nsecs).
For x86-style CMOS set_offset_nsec should be -0.5 s which causes the last
second to be written 0.5 s after it has started.
For compat with the old rtc_set_ntp_time, the value is defaulted to
+ 0.5 s, which causes the next second to be written 0.5s before it starts,
as things were before this patch.
Testing shows many non-x86 RTCs would like set_offset_nsec ~= 0,
so ultimately each RTC driver should set the set_offset_nsec according
to its needs, and non x86 architectures should stop using
update_persistent_clock64 in order to access this feature.
Future patches will revise the drivers as needed.
Since CMOS and RTC now have very different handling they are split
into two dedicated code paths, sharing the support code, and ifdefs
are replaced with IS_ENABLED.

Our ctags mangling script can't handle newlines inside of a
DEFINE_PER_CPU(), leading to an annoying message whenever tags are
built:
ctags: Warning: drivers/clocksource/arm_arch_timer.c:302: null expansion of name pattern "\1"
This was dealt with elsewhere in commit:
25528213fe9f75f4 ("tags: Fix DEFINE_PER_CPU expansions")
... by ensuring each DEFINE_PER_CPU() was contained on a single line,
even where this would violate the usual code style (checkpatch warnings
and all).
Let's do the same for the arch timer driver, and get rid of the
distraction.

The ACPI GTDT code validates the CNTFRQ field of each MMIO timer
frame against the CNTFRQ system register of the current CPU, to
ensure that they are equal, which is mandated by the architecture.
However, reading the CNTFRQ field of a frame is not possible until
the RFRQ bit in the frame's CNTACRn register is set, and doing so
before that willl produce the following error:
arch_timer: [Firmware Bug]: CNTFRQ mismatch: frame @ 0x00000000e0be0000: (0x00000000), CPU: (0x0ee6b280)
arch_timer: Disabling MMIO timers due to CNTFRQ mismatch
arch_timer: Failed to initialize memory-mapped timer.
The reason is that the CNTFRQ field is RES0 if access is not enabled.
So move the validation of CNTFRQ into the loop that iterates over the
timers to find the best frame, but defer it until after we have selected
the best frame, which should also have enabled the RFRQ bit.

We regularly run into build errors when a clocksource driver selects
CONFIG_TIMER_OF while CONFIG_GENERIC_CLOCKEVENTS is disabled:
In file included from drivers/clocksource/timer-of.c:25:0:
drivers/clocksource/timer-of.h:35:28: error: field 'clkevt' has incomplete type
At the moment, three drivers can show this behavior: ARMV7M_SYSTICK,
CLKSRC_ST_LPC and CLKSRC_NPS. We could add further dependencies as we did
many times, but I have looked a little bit more at what architectures
are left that don't use GENERIC_CLOCKEVENTS, and this shows that there
is a better solution.
On arch/frv and arch/ia64, we never select CONFIG_GENERIC_CLOCKEVENTS
and we also don't use ARCH_USES_GETTIMEOFFSET, which would
block the clocksource Kconfig menu. On m68k, some platforms use
CONFIG_GENERIC_CLOCKEVENTS, some use ARCH_USES_GETTIMEOFFSET, and some
use neither of them. The good news is that there is no configuration that
does not set CONFIG_GENERIC_CLOCKEVENTS but that wants to enable any of
the Kconfig symbols in the menu, so we can simply replace the dependency
with the stricter one. While in theory one could have a clocksource
driver without the clockevent infrastructure, this seems unlikely
to be relevant in the future any more.
We can probably drop some of the other dependencies as well now,
e.g. there should generally be no reason to depend on CONFIG_ARM
unless the driver uses architecture specific assembly.

for the old DT binding is still kept around, however devices using
such binding will be treated as a low-feature CMT0 device. If users
want to make use of CMT1-specific features then they need to update
their DTBs. No special CMT1-specific features are however implemented
by his patch, only DT bindings are redone as groundwork for future

Remove uses of init_timer_on_stack() with open-coded function and data
assignments that could be expressed using timer_setup_on_stack(). Several
were removed from the stack entirely since there was a one-to-one mapping
of parent structure to timer, those are switched to using timer_setup()
instead. All related callbacks were adjusted to use from_timer().

Pull driver core fixes from Greg KH:
"Here are a few small fixes for 4.14-rc4.
The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
straggler made it in through some other tree (odds are, one of
mine...) So there's a simple removal of the last user, and then
finally the macro is removed from the tree.
There's a fix for old crazy udev instances that insist on reloading a
module when it is removed from the kernel due to the new uevents for
bind/unbind. This fixes the reported regression, hopefully some year
in the future we can drop the workaround, once users update to the
latest version, but I'm not holding my breath.
And then there's a build fix for a linker warning, and a buffer
overflow fix to match the PCI fixes you took through the PCI tree in
the same area.
All of these have been in linux-next for a few weeks while I've been
traveling, sorry for the delay"

where an obvious hardware level failure results in an unnecessary 15 second
delay and a subsequent crash.
So record the result code of ahci_reset_controller() and relay it, rather
than ignoring it.

Pull x86 fixes from Thomas Gleixner:
"This contains the following fixes and improvements:
- Avoid dereferencing an unprotected VMA pointer in the fault signal
generation code
- Fix inline asm call constraints for GCC 4.4
- Use existing register variable to retrieve the stack pointer
instead of forcing the compiler to create another indirect access
which results in excessive extra 'mov %rsp, %<dst>' instructions
- Disable branch profiling for the memory encryption code to prevent
an early boot crash
- Fix a sparse warning caused by casting the __user annotation in
__get_user_asm_u64() away
- Fix an off by one error in the loop termination of the error patch
in the x86 sysfs init code
- Add missing CPU IDs to various Intel specific drivers to enable the
functionality on recent hardware
- More (init) constification in the numachip code"
