41b7602ed1 microblaze: Fix access_ok macro
There is the problem with bit OR (|) because for
some combination is addr | size | addr+size equal
to seq.

For standard kernel setting (kernel starts at 0xC0000000)
is seq for user space 0xBFFFFFFF and everything below
this limit is fine.

But even address 0xBFFFFFFF is fine because it

ec4f5423b5 ARM: S3C2443: Remove redundant s3c_register_clocks call for init_clocks
Since commit af337f3e63
"ARM: S3C2443: Move parts of the clock code to common clock file",
the init_clocks array is moved to arch/arm/plat-s3c24xx/s3c2443-clock.c.
Now we call s3c_register_clocks for init_clocks in s3c2443_common_init_clocks.

Thus we can remove the empty init_clocks array here and remove the
redundant s3c_register_clocks call for init_clocks in s3c2443_init_clocks.

5227a54a0f ARM: S3C24XX: Add devname for hsmmc1 pclk
S3C2443 uses hsmmc1 as its only hsmmc device and for S3C2416/S3C2450
it's the second hsmmc channel with the same PCLKCON bit.
The hsmmc-if clocks on both systems already got a devname, as did
the hsmmc pclk for hsmmc0 on the S3C2416. So to make it possible to
identify the hsmmc1 pclk on S3C2416 add the correct devname for it.
The sclk name on S3C2443 also is s3c-sdhci.1.

33ccedfd1b ARM: S3C24XX: use clk_get_rate to init fclk in common_setup_clocks
Previously the fclk rate was calculated by dividing the pll through
the divider value of the armdiv. With a real armdiv clk in place it's
possible to simply read its value, which does essentially the same.

This change makes the whole fdiv_fn function pointers supplied to
s3c2443_common_init_clocks and s3c2443_common_setup_clocks
obsolete, so remove it too.

866a1c8c35 ARM: S3C2443: Accommodate cpufreq frequency scheme in armdiv
Cpufreq uses frequencies in kHz and not Hz, so set_rate and round_rate
would be called with a frequency of 266666000 instead of 266666666 but
the clock functions check for rates smaller or equal to the targetrate.

As the armdiv does not support steps this small we can accommodate
this by simply also setting the last 3 digits of the calculated rate
to zero.

153b19a3b9 x86, mrst: use a temporary variable for SFI irq
SFI tables reside in RAM and should not be modified once they are
written.  Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum.  This will
break kexec as the second kernel fails to validate SFI tables.

To fix this we use temporary variable for irq number.

bf164c58e5 hwmon: (w83627ehf) Properly report thermal diode sensors
The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.
