Subject: m32r: define pgprot_noncached
Date: Tue, 23 Jun 2009 15:07:11 +0200 [thread overview]
Message-ID: <200906231507.11817.arnd@arndb.de> (raw)
In-Reply-To: <200906231441.37158.arnd@arndb.de>
On m32r, pgprot_noncached is an inline function and not a macro,
which means that various bits of code that check its presence
with #ifdef never get to call it.
In particular, the asm-generic version of that macro would
override it.
This adds a self-referencing macro like other architectures do
it to make the checks work correctly.
