We will set the link-list pointer register point to next link-list
configuration's physical address, which can load DMA configuration
from the link-list node automatically.
But the link-list node's physical address can be larger than 32bits,

Emulation of VMPTRST can incorrectly inject a page fault
when passed an operand that points to an MMIO address.
The page fault will use uninitialized kernel stack memory
as the CR2 and error code.
The right behavior would be to abort the VM with a KVM_EXIT_INTERNAL_ERROR
exit to userspace;

First two patches are to do cleanup, remove redundant assignment,

Third patch is to fix memory leak for sctp_do_bind if failed

This VM has 4G memory and 2 CPUs. And I set up 4G swap in /swapfile.

- Rebased on top of Zhang's "next" branch
-
We can simplify error cleanup code if instead of passing a "struct

pointers from it, we pass those pointers directly. This way we won't
be force to call platform_set_drvdata() as early in qoriq_tmu_probe()
and need to have
Embed per-sensor data into struct qoriq_tmu_data so we can drop the
code allocating it. This also allows us to get rid of per-sensor back

Mask of slub objects per page shouldn't be larger than what
page->objects can hold.
It requires more than 2^15 objects to hit the problem, and I don't
think anybody would. It'd be nice to have the mask fixed, but not
really worth cc'ing the stable.

The action of saving the PCI state will cause numerous PCI configuration
space reads which depending upon the vendor implementation may cause
the drive to exit the deepest NVMe state.
In these cases ASPM will typically resolve the PCIe link state and APST
may resolve the NVMe power state.
Update the Shutdown IC version to 3.2, which is required for the host to
send the hibernation request.
The user is expected to create the program "/sbin/hyperv-hibernate", which
is called on the host-initiated hibernation request.
The program can be a script like
test@localhost:~$ cat
On hibernation, Linux can not guarantee the host side utils operations
still succeed without any issue, so let's simply cancel the work items.
The host is supposed to retry the operations, if necessary.

This patch is basically a pure Hyper-V specific change and it has a
build dependency on the commit 271b2224d42f ("Drivers: hv: vmbus: Implement
suspend/resume for VSC drivers for hibernation"), which is on Sasha Levin's
Hyper-V tree's hyperv-next branch:
A VM can have multiple hbus. It looks incorrect for the second hbus's
hv_pci_protocol_negotiation() to set the global variable
'pci_protocol_version' (which was set by the first hbus), even if the
same value is written.

When hibernation is enabled, we must ignore the balloon up/down and

Fow now, if people want to test hibernation, please blacklist hv_balloon

When we're in storvsc_suspend(), we're sure the SCSI layer has quiesced the
scsi device by scsi_bus_suspend() -> ... -> scsi_device_quiesce(), so the
low level SCSI adapter driver only needs to suspend/resume its own state.

Commit 7290d5809571 ("module: use relative references for __ksymtab
entries") converted the '__put' #define into an assembly macro in
asm-generic/export.h but forgot to remove the corresponding '#undef'.
Remove the leftover '#undef'.
