[Xen-devel] Porting PV-on-HVM for ia64 platform (Take 3)

[DOI Tsunehisa <Doi.Tsunehisa@xxxxxxxxxxxxxx>]

Hi,

  I will post patches for PV-on-HVM on ia64 platform.

  These patch include:

   * unmodified-driver.patch
     + cut off unused codes for IPF
       - get_hypercall_stabs() is x86 specific function. We don't
         use it, and it occurrs compile error on ia64 platform.
         Thus it is cut off.
   * unmodified-build.patch
     + modify build rule for IPF
       - This patch appends a build rule for ia64 platform to
         mkbuildtree command.

Thanks,
- Tsunehisa Doi
