[PATCH] Add two arch hooks to gnttab_release_mappings()
Add two arch hooks to gnttab_release_mappings().
The c/s 8409:b3edbeea3e79 changed gnttab_release_mappings() such that
it doesn''t put page/type reference count because it is done implicitly
when page table is destructed.
It is x86 specific issue and it isn''t the case for ia64 and powerpc.
Introduce two arch hook to address it...

implicit grant unmap
Hello All,
I''m contemplating ways to avoid the domain_crash() in mm.c line ~615
without requiring new OS hooks. This crash occurs when the operating
system writes a zero to the PTE for a grant mapping without an explicit
Xen call to unmap.
In hacking around, it seems the problem is this: When the mapping PTE
gets squashed, Xen''s cleanup_writable_pagetable() has no way to find

RE: [Patch][RFC] Support "xm dump" (is Re: Re: [Patch]Enable "sysrq c" handler for domU coredump)
Two things:
1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this
(and if you want
a dump, do ''xm dump'' followed by ''xm destroy'')
2. I don''t see the point of the --noreboot option on ''xm dump'' -- I
think this command
should simply live-dump the specified domain - as
