Subject: [PATCH 07/17] UAPI: Rearrange definition of HZ in asm-generic/param.h
Date: Tue, 13 Dec 2011 10:04:03 +0000	[thread overview]
Message-ID: <1323770653-19177-8-git-send-email-dhowells@redhat.com> (raw)
In-Reply-To: <1323770653-19177-1-git-send-email-dhowells@redhat.com>

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.
