Re: [XenPPC] noHV status

[Mark F Mergen <mergen@xxxxxxxxxx>]

Sorry Maria!  You took those files
nohv.[c|h] from my tree just as I had started making new mods.  I
know these should be part of the Xen patch, but then it makes the Xen diff
much less useful to me for development.  I always keep working copies
of these and other modified files in the root of the tree /a/kix/homes/kix/mergen.
 So please take nohv.[c|h] from this location, but put them at xen/arch/powerpc/powerpc64/nohv.c
and xen/include/asm-powerpc/nohv.h as in the original note.

I apologize for the trouble you've had.
Mark

Beside the patches and the files you mentioned before, nohv.[hc] what 
else does one need.  Currently I cannot compile

nohv.c: In function `h_create_vm_area':
nohv.c:107: error: `DOMF_' undeclared (first use in this function)
nohv.c:107: error: (Each undeclared identifier is reported only once
nohv.c:107: error: for each function it appears in.)
nohv.c:107: error: parse error before "switch"
nohv.c:110: error: break statement not within loop or switch
nohv.c:100: warning: unused variable `vma'
nohv.c: At top level:
nohv.c:113: error: parse error before "if"
