for periodically updating the CMOS RTC was moved to:kernel/time/ntp.c

of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.@@

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.Signed-off-by: Al Viro

HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more
correct. (http://bugzilla.kernel.org/show_bug.cgi?id=11111)Note that when using the legacy RTC driver, platforms don't really do a
dynamic switch between HPET and non-HPET modes based on whether HPET
hardware actually exists ... only rtc-cmos (using the new RTC framework)
currently switches that way.So this reflects bitrot in that legacy code, for x86/ia64: kernels with
HPET support configured (e.g. for a clocksource) can't get IRQs from the
legacy RTC driver unless they really have HPET hardware. (The obvious
workaround is to not use the legacy RTC driver on those platforms when you
configure HPET ... unless you know the target really has a HPET.)Signed-off-by: David Brownell

The IRQ rate reported back by the RTC is incorrect when HPET is enabled.
Newer hardware that has HPET to emulate the legacy RTC device gets this value
wrong since after it sets the rate, it returns before setting the variable
used to report the IRQ rate back to users of the device -- so the set rate and
the reported rate get out of sync.Signed-off-by: Paul Gortmaker

the previous patch in the old RTC driver. It also removes the direct
rtc_interrupt() call from arch/x86/kernel/hpetc.c so that there's finally no
(code) dependency to CONFIG_RTC in arch/x86/kernel/hpet.c.Because of this, it's possible to compile the drivers/char/rtc.ko driver as
module and still use the HPET emulation functionality. This is also expressed
in Kconfig.Signed-off-by: Bernhard Walle

Firmware like PNPBIOS or ACPI can report the address space consumed by the
RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT)
assumed by the RTC driver.The PNP core doesn't request resources yet, but I'd like to make it do so.
If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC
driver from loading.Since we only use the RTC index and data registers at RTC_PORT(0) and
RTC_PORT(1), we can fall back to requesting just enough space for those.If the PNP core requests resources, this results in typical I/O port usage
like this:0070-0073 : 00:06

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.Signed-off-by: Eric W. Biederman
