d2eea68e7d xen: disable vdso "nosegneg" on native boot
One of the nice ideas behind paravirt is that CONFIG_XEN=y can be included
in a standard configuration and be no worse for native booting than as a
Xen guest.  The glibc feature that supports the vDSO "nosegneg" note is
designed specifically to make this easy.  You just have to flip one bit at
boot time.  This patch makes Xen flip the bit, so a CONFIG_XEN=y kernel on
bare hardware does not make glibc use the less-optimized library builds.

processor variants including 7091, 7750, 7750s, 7750r, 7751 and
7751r should all have the correct vectors hooked up.

ee54505199 sh: update r2d defconfig and fix SH7751R pci compliation
This patch updates the r2d board support in a few ways:

- CPU_SUBTYPE_SH7751R is selected in the defconfig to play well
  with the r2d board Kconfig entry. Without this the defconfig
  results in no board enabled.

- Enable EARLY_PRINTK.
- Enable SH_STANDARD_BIOS
	- this works well for early printk on the r2d board.

- Add "earlyprink=bios" to the cmdline for early serial port
  output by default.

- CONFIG_SUBTYPE_SH7751R support is added to the sh-specific
  pci makefile.

We try to fetch the CIF entry pointer from %o4, but that

in %l7 already, so actually this "mov %o4, %l7" can just
be completely removed with no other changes.

cb5ec75b8b sh: cpufreq: clock framework support.
This gets the SH cpufreq working again. We follow the changes
in the AVR32 implementation for wrapping in to the clock framework.
CPUs that wish to use this are required to define rate rounding
primitives in order to satisfy clk_round_rate().

This works well enough for the common case, though we should
look at unifying this driver across all of the platforms that
implement clock framework support in one capacity or another.
