This is to allow the sis5595 hardware monitoring driver to also

i2c-viapro and via686a drivers to let them both load.

4b2643d7d9 i2c: Fix the i2c_smbus_read_i2c_block_data() prototype
Let the drivers specify how many bytes they want to read with
i2c_smbus_read_i2c_block_data(). So far, the block count was
hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
Many driver authors complained about this before, and I believe it's
about time to fix it. Right now, authors have to do technically stupid
things, such as individual byte reads or full-fledged I2C messaging,
to work around the problem. We do not want to encourage that.

I even found that some bus drivers (e.g. i2c-amd8111) already
implemented I2C block read the "right" way, that is, they didn't
follow the old, broken standard. The fact that it was never noticed
before just shows how little i2c_smbus_read_i2c_block_data() was used,
which isn't that surprising given how broken its prototype was so far.

There are some obvious compatiblity considerations:
* This changes the i2c_smbus_read_i2c_block_data() prototype. Users
  outside the kernel tree will notice at compilation time, and will
  have to update their code.
* User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
  the changed expectations would affect tools such as i2cdump. In order
  to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
  a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
  old numeric value. When i2c-dev receives a transaction with the
  old value, it can convert it to the new format on the fly.

ba7fbb723f i2c: Deprecate legacy RTC drivers
We have a new RTC subsystem with better drivers.

Legacy driver status:
* ds1337: The DS1337 and DS1339 are now supported by the rtc-ds1307
  driver, so it looks to me like we could even delete the ds1337
  driver right away.
* ds1374: Will soon be replaced with Scott Wood's rtc-ds1374 driver.
* m41t00: The M41T00 is supported by the rtc-ds1307 driver. For the
  M41T81 and M41T85, the rtc-m41t80 driver written by Atsushi Nemoto
  should work.

4486b86368 [ARM] riscpc: fix decompressor font file handling
font_acorn_8x8.o was being built in drivers/video/console/ twice
during a build _in the same location_ - once for the kernel proper,
and once for the decompressor.  The result is when you came to run an
install target, the kernel was always rebuilt due to this file
apparantly having been built with different compiler arguments.

Solve this by making a local copy at build time in the decompressor's
directory.
