[Xen-devel] [PATCH 00/02] broken page handle wrt migration

["Liu, Jinsong" <jinsong.liu@xxxxxxxxx>]

These 2 patches are used to handle broken page wrt migration. Generally there 
are 2 cases: the broken page occur before migration, and the broken page occur 
during migration.

Patch 01 handles the case that broken page occurred before migration: At the 
sender, the broken page would not be copied to target while its pfn_type and 
pfn number would be transferred to target, so that at target, it would set p2m 
as p2m_ram_broken for broken page.

Patch 02 handles the case that broken page occurred during migration: At the 
sender, marks the broken page to dirty bitmap, so that at copypages stage of 
migration, its pfn_type and pfn number would transfer to target. At the target, 
it would set p2m as p2m_ram_broken for broken page.

Thanks,
Jinsong
