[PATCH 7/20] UML - Add back CONFIG_HZ

[PATCH 7/20] UML - Add back CONFIG_HZ

[Jeff Dike]

avoid-overflows-in-kernel-timec.patch makes CONFIG_HZ necessary for a
successful build.  UML lacks a definition, so this patch adds one.  It
also changes the hard-wired definition of HZ to CONFIG_HZ.

Note: this patch is a good idea even in the absence of hpa's time
fixes.
