Re: [Xen-ia64-devel] [RFC] Patches for supporting Xwindow on ourPRIMEQUEST

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Kama and all

You'd better post a patch per email.
I hope you find it informative. :-)
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt?

I have a comment.
If these patches are applied,
xen-ia64 don't need to use drivers/xen/char/mem.c, right?
If so, we should modify Makefile and Kconfig
related to drivers/xen/char/mem.c, shouldn't we?

Best Regards,

Akio Takebe
