David Howells 3d7f1dc195 UAPI: Rearrange definition of HZ in asm-generic/param.h
Rearrange the definition of HZ in asm-generic/param.h so that the user-specific
is declared before the kernel-specific one.  We then explicitly #undef the
userspace HZ value and replace it with the kernel HZ value.

This allows the userspace params to be excised into a separate header as part
of the UAPI header split.
