9aa6933892 hwmon: (f75375s) On n2100 systems, set fans to full speed on boot
On thecus n2100, the bootloader does not setup fans to run. In order
to protect the user from frying their gear, start up fans on boot.

d2cb0e6ecb [S390] tod clock: announce clocksource as perfect
The Time of Day clock is the standard time source for s390. It is
- monotonic
- allows very fast reading
- architecture guarantees at least microsecond stepping
- available as part of the architecture

We should announce the rate of tod as 400 to be in sync with the
description found in clocksource.h:
"400-499:Perfect The ideal clocksource. A must-use where available."

This change will prefer tod over less reliable clock sources.

69d39d6669 [S390] Rename "idle_time" attribute to "idle_time_us".
Seems that people prefer to have the unit encoded in the attribute
name. Also makes parsing easier.

Now we have:

# cat /sys/devices/system/cpu/cpu0/idle_time_us
131473592

instead of

# cat /sys/devices/system/cpu/cpu0/idle_time

0d2be08893 [S390] Fix compile on !CONFIG_SMP.
Commit fae8b22d3e
"[S390] Add per-cpu idle time / idle count sysfs attributes" causes
a link error on !CONFIG_SMP.
Fix this by adding some #ifdef's. Real fix would be to cleanup the
code since we don't register a cpu on !CONFIG_SMP. But that would
be quite a big patch. For the time being this is good enough.

74521c28e5 Use i8253.c lock for PC speaker on MIPS, too.
The Jazz machines have to use the PIT timer for dyntick and highresolution
kernels.  This may break because currently just like i386 used to do MIPS
uses two separate spinlocks in the actual PIT code and the PC speaker
code.  So switch to do it the same that x86 currently does PIT locking.

b5751e2e00 sh: Fix up r7780rp highlander CF access size.
R7780RP can't do byte-sized accesses to CF, so needs to do word

on older versions of the R2D, with the same workaround having
been implemented in 43f4b8c757
there. Follow that change for the highlander boards.

This does not impact R7780MP or SH7785 based Highlander modules.

f38c5a696a sh: Terminate .eh_frame in VDSO with a 4-byte 0.
It's assumed that .eh_frame is terminated with 4-byte 0 in shared
libraries and executable.  It seems to be the case for VDSOs too.
Without this terminator, I saw failures when unwinding from VDSO,
though I don't know how other architectures handle this issue.
For the normal libs, crtendS.o gives this terminator.  We can use
such terminating objects.  Or we can add a 4-byte 0 with modifying
the linker script like as the patch below.
