This function isn't much needed as NAPI skb queue gets bulk-freed
anyway when there's no more room, and even may reduce the efficiency
of bulk operations.
It will be even less needed after reusing skb cache on allocation path,
so remove it and this way lighten network softirqs a bit.

Instead of just bulk-flushing skbuff_heads queued up through
napi_consume_skb() or __kfree_skb_defer(), try to reuse them
on allocation path.
If the cache is empty on allocation, bulk-allocate the first
half, which is more efficient than per-skb allocation.
If the cache is full on freeing, bulk-wip

alloc_page_buffers() currently uses get_mem_cgroup_from_page() for
charging the buffers to the page owner, which does an rcu-protected
page->memcg lookup and acquires a reference. But buffer allocation has
the page lock held throughout, which pins the page to the memcg and

Try to use the same technique for obtaining skbuff_head from NAPI
cache in {,__}alloc_skb(). Two points here:
- __alloc_skb() can be used for allocating clones or allocating skbs
for distant nodes. Try to grab head from the cache only for
non-clones and for local nodes;

Currently, all sorts of skb allocation always do allocate
skbuff_heads one by one via kmem_cache_alloc().
On the other hand, we have percpu napi_alloc_cache to store
skbuff_heads queued up for freeing and flush them by bulks.
We can use this cache not only for bulk-wiping, but also to obtain
heads

Add an atomic field which stores the physical offset of the last I/O
operation scheduled to the device. This information is going to be used
to measure the locality of I/O requests.

This patch series adds a new raid1 read policy - roundrobin. For each
request, it selects the mirror which has lower load than queue depth.
Load is defined as the number of inflight requests + a penalty value
(if the scheduled request is not local to the last processed requ
This patch extends the br_mrp_switchdev functions to be able to have a
better understanding what cause the issue and if the SW needs to be used
as a backup.
There are the following cases:
- when the code is compiled without CONFIG_NET_SWITCHDEV. In this case
return success so the SW can continue

MSM8994, despite being heavily based on MSM8974, uses the
1.2 version of TSENS. Also, 8994 being 8994, it has a custom
way of calculating the slope.
Also tested on 8976 (by a person who didn't want to be named)
to make sure the 11->16 max_sensors changes didn't break anything.

This series implements C syscall entry/exit for PPC32. It reuses
the work already done for PPC64.
This series is based on today's next-test (f538b53fd47a) where main patchs from
v5 are merged in.
The first patch is important for performance.
v6:
- Forced scv param to 0 on syscall_exit_prepare()
This patch fixes a circular locking dependency in the CI introduced by
commit f21916ec4826 ("s390/vfio-ap: clean up vfio_ap resources when KVM
pointer invalidated"). The lockdep only occurs when starting a Secure
Execution guest. Crypto virtualization (vfio_ap) is not yet supported for
SE guests; h
Patch f21916ec4826 ("s390/vfio-ap: clean up vfio_ap resources when KVM
pointer invalidated") introduced a change that results in a circular
locking dependency when a Secure Execution guest that is configured with
crypto devices is started. The problem resulted due to the fact that the
patch moved t
The handling of SPRN_DBCR0 and other registers can easily
be done in C instead of ASM.
For that, create booke_load_dbcr0() and booke_restore_dbcr0().

Only book3s/64 has scv. No need to check the 0x7ff0 trap on 32 or 64e.
For that, add a helper trap_is_unsupported_scv() similar to
trap_is_scv().

By default dma_buf_export() sets the exporter name to be
KBUILD_MODNAME. Unfortunately this may not be identical to the
string used as the heap name (ie: "system" vs "system_heap").
This can cause some minor confusion with tooling, and there is
the future potential where multiple heap types may be
