Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such
NVRAM (or on many systems, EEPROM) data is often initialized during system
manufacture to hold data about identity (serial numbers, Ethernet addresses,
etc), configuration, calibration, and so forth.
This patch improves integrity and security of those files:
- Correctly initializes the size in one of the two cases where
that was not yet being done.
- Improves system security/integrity by making this state not
be world-writable by default.
Letting arbitrary userspace code mangle such state by default is at least Not
A Good Thing; and it could sometimes be worse, depending on the particular
data that might be corrupted. (I disregard the paranoiac "don't let anyone
read it either" approach. Anyone storing passwords in such memory doesn't
really care about security.)

The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local

This patch fixes rtc-cmos to ignore the two upper bits when reading the

The older /proc/ interface ignores the upper bits, and so we should too.

- Claim those ports earlier, to help work around procfs bugs

- Fix some glitches in cleanup code, notably a cut'n'paste-o
where the i/o port region might not get released during

Fix readback of RTC alarms on platforms which return -1 in
non-hardware-supported RTC alarm fields.
To fill in the missing (-1) values, we grab an RTC timestamp along with the
RTC alarm value, and use the timestamp fields to populate the missing alarm
fields.
To counter field-wrap races (since the timestamp and alarm are not read
together atomically), we read the RTC timestamp both before and after
reading the RTC alarm value, and then check for wrapped fields --> if any
have wrapped, we know we have a possible inconsistency, so we loop and
reread the timestamp and alarm again.
Wrapped fields in the RTC timestamps are an issue because rtc-cmos.c, for
example, also gets/uses an RTC timestamp internally while fetching the RTC
alarm. If our timestamp here wasn't the same (minutes and higher) as what
was used internally there, then we might end up populating the -1 fields
with inconsistent values.
This fixes readbacks from /sys/class/rtc/rtc?/wakealarm, as well as other
code paths which call rtc_read_alarm().

This avoids use of the kernel-internal "xtime" variable directly outside

that we already have available to us.
This doesn't actually change any behaviour, but this will allow us to
fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
(because much of the realtime information is maintained as separate
offsets to 'xtime'), which has caused interfaces that use xtime directly
to get a time that is out of sync with the real-time clock by up to a
third of a second or so.
