Subject: [PATCH] gxfb: move MSR bit fields into gxfb.h
This continues the gxfb header cleanups. MSRs are defined in geode.h;
the specific bits we care about are defined in gxfb.h.

Something has gone wrong here. The code in current mainline is
extern struct geode_dc_ops gx_dc_ops;
/* MSR that tells us if a TFT or CRT is attached */
#define GLD_MSR_CONFIG 0xC0002001
#define GLD_MSR_CONFIG_DM_FP 0x40
/* Display controller registers */
whereas you're patching something else.
In [1/6] you refer to "the MSR cleanup patch". I don't know what that is.
Please clean up the changelogs - remove those email headers from the
email-forwarding operation and remove the additional little commentary on
top: if there's actually anything in there which is needed then it should
be integrated into the changelog proper, thanks.

For future requests, or should I resend these to you?

Oh, that. OK, I found that and it still applies and it makes these new
patches apply.

Well I cleaned these up and was ready to go, but I think some updates are
needed, please. So please consider, redo and resend everything, including
the already-acked-by-Jordan MSR cleanup.

This continues the gxfb header cleanups. MSRs are defined in geode.h;
the specific bits we care about are defined in gxfb.h.
