Currently, the powerpc kvm_arch structure contains a number of variables
tracking the state of the guest's hashed page table (HPT) in KVM HV. This
patch gathers them all together into a single kvm_hpt_info substructure.
This makes life more convenient for the upcoming HPT resizing
implementation.
The difference between kvm_alloc_hpt() and kvmppc_alloc_hpt() is not at
all obvious from the name. In practice kvmppc_alloc_hpt() allocates an HPT
by whatever means, and calls kvm_alloc_hpt() which will attempt to allocate
it with CMA only.
To make this less confusing, rename kvm_alloc_hpt() to k
The KVM_PPC_ALLOCATE_HTAB ioctl() is used to set the size of hashed page

Currently, kvmppc_alloc_hpt() both allocates a new hashed page table (HPT)

So, split the allocation itself out into kvmppc_allocate_hp
The kvm_unmap_rmapp() function, called from certain MMU notifiers, is used

Here is the KVM implementation for the proposed PAPR extension which
allows the runtime resizing of a PAPR guest's Hashed Page Table (HPT).
Using this requires a guest kernel with support for the extension.
Patches for guest side support in Linux were posted earlier:
https://lists.ozlabs.org/pip
This adds a new powerpc-specific KVM_CAP_SPAPR_RESIZE_HPT capability to
advertise whether KVM is capable of handling the PAPR extensions for
resizing the hashed page table during guest runtime.
At present, HPT resizing is possible with KVM PR without kernel
modification, since the HPT is managed w
This updates the KVM_CAP_SPAPR_RESIZE_HPT capability to advertise the

This is just a reposting of the patch that enables endian checks, with addition
of trivial patches that drop __bitwise__ and __CHECK_ENDIAN__ everywhere.
I plan to include this in my pull request unless I hear otherwise.
Michael S. Tsirkin (8):
linux/types.h: enable endian checks for all sparse
By now, linux is mostly endian-clean. Enabling endian-ness
checks for everyone produces about 200 new sparse warnings for me -
less than 10% over the 2000 sparse warnings already there.
Not a big deal, OTOH enabling this helps people notice
they are introducing new bugs.
So let's just drop __CHEC
__bitwise__ is an implementation detail now.

only driver updates. The ST FDMA driver updates feature the remoteproc
changes as well which are coordinated with Bjorn.

CRASH_KERNEL_ADDR_MAX was missing for a long time, update it
with more detailed explanation.

Hi all,
Please do not add any material for v4.11 to your linux-next included

Linus,
Please pull below to receive modules updates for the 4.10 merge window.
This development cycle has been pretty quiet, mostly code cleanups, small
bugfixes. Summary and details in the tag.
Thanks,

->qsmask of an RCU leaf node is usually more sparse than the
corresponding cpu_possible_mask. So replace the
for_each_leaf_node_possible_cpu() in force_qs_rnp() with
for_each_leaf_node_cpu() to save several checks.
[Note we need to use "1UL << bit" instead of "1 << bit" to generate the

The ->expmask of an RCU leaf node should be more sparse than the
corresponding part of cpu_possible_mask, iterating over ->expmask bitmap
rather cpu_possible_mask to save some checks.

Use for_each_leaf_node_cpu() in RCU stall checking code, to save some
extra checks, based on the fact that ->qsmask is mostly more sparse than
cpu_possible_mask.

Though mostly identical, ->qsmaskinit(A.K.A rcu_rnp_online_cpus()) is
sometimes more sparse than the corresponding part of cpu_possible_mask
for an RCU leaf node. So we use for_each_leaf_node_cpu() in
rcu_boost_kthread_setaffinity() instead to save some extra checks.

There are some places inside RCU core, where we need to iterate all mask
(->qsmask, ->expmask, etc) bits in a leaf node, in order to iterate all
corresponding CPUs. The current code iterates all possible CPUs in this
leaf node and then checks with the mask to see whether the bit is set.
However, g

Changes since v1:
* Rename the primitive to for_each_leaf_node_cpu() for a shorter and
hopefully better name
* Fix a bug report by Colin King about bit shifting
* Drop iterator @bit based on suggestions from Mark

Hi Doug, Brain,
Thanks for the reply.
Sorry I forgot these patches have been sent earlier, and Frank have
some explained and discussed with Heiko.
Please see https://patchwork.kernel.org/patch/9255245/
Perhaps we can move to that patch tree to continue the discussion.

Yes.
So I feel we'd better to make stack user and o2cb behaves the same,
other than treat it as a special case.
Yes, I agree. But, actually, there is nothing wrong wit

The virtio crypto device is a virtual cryptography device

virtual machines. The encryption anddecryption requests

- use per virtqueue lock instead of a whole device lock

using get_cpu/put_cpu instead of calling smp_processor_id() directly.
