Subject: [PATCH 0/3] Globally defining phys_addr_t
Date: Thu, 11 Sep 2008 01:31:39 -0700	[thread overview]
Message-ID: <48C8D76B.10901@goop.org> (raw)

Hi Ingo,

This is a repost of a little 3-patch series which Andrew has been
carrying in -mm.  It cleans up the definition of phys_addr_t to make it
kernel-wide rather than x86-specific, and fixes up PFN_PHYS() to use it
to avoid address truncation.

We currently have a few workarounds for this problem in the tree, but
Alex found another bug caused by PFN_PHYS(), so it's probably better if
you bring these patches into tip.git for now.

PowerPC also defines a phys_addr_t with the same meaning as x86; the
powerpc arch maintainers are happy with these patches.

The third patch in the series is not necessary to fix any bug, but it
removes the separate definition of resource_size_t to define it in terms
of phys_addr_t.  I include it for competeness.

Thanks,
    J
