Re: [Xen-devel] [PATCH] [GNTTAB] expandable grant table

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Attached the updated patches. Please find them

- 13985_4fa9b86d41b8_grow_granttable_acm.patch
        acm part. I did only compile test.

- 13986_cca098fd122c_grow_granttable_ia64.patch
        ia64 part.

- 13987_f5f232aef7bd_grow_granttable_powerpc.patch
        powerpc part. This patch prohibits growing grant table.
        I didn't even compile test.
        It needs review by xen/powerpc developers and they may
        have their own opinions.

Thanks,
