mfd: cros_ec: Use the proper size when looking at the cros_ec_i2c result

We know how many bytes the EC should be sending us (which is also the
number of bytes transferred) and also how many bytes the EC actually
wanted to send to us.  When computing the checksum and copying back
data let's make sure we take the lesser of the two of those.  We'll
also complain if the EC tried to send us too many bytes.  The EC
sending us too few bytes is legit for when we send the EC an invalid
command.

This is based on similar code in cros_ec_spi.

ARM: sunxi: Reintroduce the restart code for A10/A20 SoCs

This partly reverts commits 553600502b84 (ARM: sunxi: Remove reset code from
the platform) and 5e669ec583e2 (ARM: sunxi: Remove init_machine callback) for
the sun4i, sun5i and sun7i families.

This is needed because the watchdog counterpart of these commits was dropped,
and didn't make it into 3.16. In order to still be able to reboot the board, we
need to reintroduce that code. Of course, the long term view is still to get
rid of that code in mach-sunxi.

Merge tag 'omap-for-v3.16/fixes-against-rc1' of git://git./linux/kernel/git/tmlind/linux-omap into fixes

Merge OMAP fixes from Tony Lindgren:

Fixes for omaps for issues discovered during the merge window and
enabling of a few features that had to wait for the driver
dependencies to clear.

The fixes included are:

- Fix am43xx hard reset flags
- Fix SoC detection for DRA722
- Fix CPU OPP table for omap5
- Fix legacy mux parser bug if requested muxname is a prefix of
  multiple mux entries
- Fix qspi interrupt binding that relies on the irq crossbar
  that has not yet been enabled
- Add missing phy_sel for am43x-epos-evm
- Drop unused gic_init_irq() that is no longer needed

And the enabling of features that had driver dependencies are:

- Change dra7 to use Audio Tracking Logic clock instead of a fixed
  clock now that the clock driver for it has been merged

- Enable off idle configuration for selected omaps as all the kernel
  dependencies for device tree based booting are finally merged as
  this is needed to get the automated PM tests working finally with
  device tree based booting

- Add hwmod entry for ocp2scp3 for omap5 to get sata working as
  all the driver dependencies are now in the kernel and this patch
  fell through the cracks during the merge window

10 years agoarm64: fix el2_setup check of CurrentEL
Marc Zyngier [Fri, 6 Jun 2014 13:16:21 +0000 (14:16 +0100)]
arm64: fix el2_setup check of CurrentEL

The CurrentEL system register reports the Current Exception Level
of the CPU. It doesn't say anything about the stack handling, and
yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h.

It works by chance because PSR_MODE_EL2t happens to match the right
bits, but that's otherwise a very bad idea. Just check for the EL
value instead.
