Thomas Gleixner 457c899653 treewide: Add SPDX license identifier for missed files
Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have EXPORT_.*_SYMBOL_GPL inside which was used in the
   initial scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

  GPL-2.0-only

Eric Wong 2a4daadd4d rtc: cmos: ignore bogus century byte
Older versions of Libreboot and Coreboot had an invalid value
(`3' in my case) in the century byte affecting the GM45 in
the Thinkpad X200.  Not everybody's updated their firmwares,
and Linux <= 4.2 was able to read the RTC without problems,
so workaround this by ignoring invalid values.

Fixes: 3c217e51d8 ("rtc: cmos: century support")

Arnd Bergmann d6faca40f4 rtc: move mc146818 helper functions out-of-line
The mc146818_get_time/mc146818_set_time functions are rather large
inline functions in a global header file and are used in several
drivers and in x86 specific code.

Here we move them into a separate .c file that is compiled whenever
any of the users require it. This also lets us remove the linux/acpi.h
header inclusion from mc146818rtc.h, which in turn avoids some
warnings about duplicate definition of the TRUE/FALSE macros.
