Maybe just:

since we already know it's in pci-hyperv.c, and it's obvious that you

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

The orion watchdog can either reset the CPU or generate an interrupt.
The interrupt would be useful for debugging as it provides panic()
output about the watchdog expiry, however if the interrupt is used the
watchdog can't reset the CPU in the event of being stuck in a loop with
interrupts disabled

Since we've just removed the dependency of vm type in previous patch,
now we can create the vm much earlier. Note that to move it earlier
we used an approximation of number of extra pages but it should be
fine.
This prepares for the follow up patches to finally remove the
duplication of guest mod
Rather than passing the vm type from the top level to the end of vm
creation, let's simply keep that as an internal of kvm_vm struct and
decide the type in _vm_create(). Several reasons for doing this:
- The vm type is only decided by physical address width and currently
only used in aarch64, s

This series originates from "[PATCH] KVM: selftests: Detect max P
Remove the duplication code in run_test() of dirty_log_test because
after some reordering of functions now we can directly use the outcome
of vm_create().
Meanwhile, with the new VM_MODE_PXXV48_4K, we can safely revert
b442324b58 too where we stick the x86_64 PA width to 39 bits for
dirty_log_test
The naming VM_MODE_P52V48_4K is explicit but unclear when used on
x86_64 machines, because x86_64 machines are having various physical
address width rather than some static values. Here's some examples:
- Intel Xeon E3-1220: 36 bits
- Intel Core i7-8650: 39 bits
- AMD EPYC 7251: 48
Issue:
- # hwclock -w
hwclock: RTC_SET_TIME: Invalid argument

At original linux design, RT & CFS scheduler are independent.
Current RT task placement policy will select the first cpu in
lowest_mask, even if the first CPU is running a CFS task.
This may put RT task to a running cpu and let CFS task runnable.
So we select idle cpu in lowest_mask first to avoid

The devicetree binding lists the phy phy as optional. As such, the
driver should not bail out if it can't find a regulator. Instead it
should just skip the remaining regulator related code and continue
on normally.
Skip the remainder of phy_power_on() if a regulator supply isn

Hi all,
After merging the block tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

There is no possibility for memmap to be NULL in the current

This check was added in commit 95a4774d055c ("memory-hotplug:

where memmap was originally inited to NULL, and only conditionally
given a value.
The code that could have passed a
