[PATCH 0/2] Fix hangup after creating checkpoint on Xen.
Hi,
The following patch series fixes hangup after creating checkpoint on
Xen. The Linux Xen guest can be saved the state to restore later, and
also created snapshot like checkpoint via the hypervisor.
But, when the snapshot is created for the PV guest, it will hangup.
We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops
struct in the pm-linux

x86: PIE support and option to extend KASLR randomization
These patches make the changes necessary to build the kernel as Position
Independent Executable (PIE) on x86_64. A PIE kernel can be relocated below
the top 2G of the virtual address space. It allows to optionally extend the
KASLR randomization range from 1G to 3G.
Thanks a lot to Ard Biesheuvel & Kees Cook on their feedback on compiler
changes, PIE support and KASLR in general. Thanks to

[PATCH v1 00/27] x86: PIE support and option to extend KASLR randomization
Changes:
- patch v1:
- Simplify ftrace implementation.
- Use gcc mstack-protector-guard-reg=%gs with PIE when possible.
- rfc v3:
- Use --emit-relocs instead of -pie to reduce dynamic relocation space on
mapped memory. It also simplifies the relocation process.
- Move the start the module section next to the kernel. Remove the need for
-mcmodel=large on modules. Extends
