Sir, attached two patch files for jeremy-kernel 2.6.32.27 and xen-4.0.1.
Current status ,I have the required huge pages' mfn (reserved before dom 0
boots )which we pass on from hypervisor to domain to enable it to use this
mfn to make required PTE .
The problem lies that domain is unable to modify the PMD (as mentioned in
above conversation) which contains this PTE entry as it lies in guest
read-only memory as shown in xen's config.h file.
So,we tried passing this PMD entry in a hypercall to the hypervisor to
modify PMD accordingly but while allocation xen crashes.
This is where we are stuck now.
