[PATCH net-next v2 0/4] add frag page support in page pool
by Yunsheng Lin
This patchset adds frag page support in page pool and
enable skb's page frag recycling based on page pool in
hns3 drvier.
V2:
1. resend based on the latest net-next.
V1:
1. avoid atomic_long_read() in case of freeing or draining
page frag, and drop RFC tag.
RFC v6:
1. Disable frag page support in system 32-bit arch and
64-bit DMA.
RFC v5:
1. Rename dma_addr[0] to pp_frag_count and adjust codes
according to the rename.
RFC v4:
1. Use the dma_addr[1] to store bias.
2. Default to a pagecnt_bias of PAGE_SIZE - 1.
3. other minor comment suggested by Alexander.
RFC v3:
1. Implement the semantic of "page recycling only wait for the
page pool user instead of all user of a page"
2. Support the frag allocation of different sizes
3. Merge patch 4 & 5 to one patch as it does not make sense to
use page_pool_dev_alloc_pages() API directly with elevated
refcnt.
4. other minor comment suggested by Alexander.
RFC v2:
1. Split patch 1 to more reviewable one.
2. Repurpose the lower 12 bits of the dma address to store the
pagecnt_bias as suggested by Alexander.
3. support recycling to pool->alloc for elevated refcnt case
too.
Yunsheng Lin (4):
page_pool: keep pp info as long as page pool owns the page
page_pool: add interface to manipulate frag count in page pool
page_pool: add frag page recycling support in page pool
net: hns3: support skb's frag page recycling based on page pool

[RFCv2 net-next 000/167] net: extend the netdev_features_t
by Jian Shen
For the prototype of netdev_features_t is u64, and the number
of netdevice feature bits is 64 now. So there is no space to
introduce new feature bit.
This patchset try to solve it by change the prototype of
netdev_features_t from u64 to bitmap. With this change,
it's necessary to introduce a set of bitmap operation helpers
for netdev features. Meanwhile, the functions which use
netdev_features_t as return value are also need to be changed,
return the result as an output parameter.
With above changes, it will affect hundreds of files, and all the
nic drivers. To make it easy to be reviewed, split the changes
to 167 patches to 5 parts.
patch 1~22: convert the prototype which use netdev_features_t
as return value
patch 24: introduce fake helpers for bitmap operation
patch 25~165: use netdev_feature_xxx helpers
patch 166: use macro __DECLARE_NETDEV_FEATURE_MASK to replace
netdev_feature_t declaration.
patch 167: change the type of netdev_features_t to bitmap,
and rewrite the bitmap helpers.
Sorry to send a so huge patchset, I wanna to get more suggestions
to finish this work, to make it much more reviewable and feasible.
The former discussing for the changes, see [1]
[1]. https://www.spinics.net/lists/netdev/msg753528.html

[PATCH net-next v6] page_pool: disable dma mapping support for 32-bit arch with 64-bit DMA
by Yunsheng Lin
As the 32-bit arch with 64-bit DMA seems to rare those days,
and page pool might carry a lot of code and complexity for
systems that possibly.
So disable dma mapping support for such systems, if drivers
really want to work on such systems, they have to implement
their own DMA-mapping fallback tracking outside page_pool.

[PATCH 1/4] rasdaemon: Fix the issue of sprintf data type mismatch in uuid_le()
by Xiaofei Tan
The data type of sprintf called in the function uuid_le() is mismatch.
Arm64 compiler force it to unsigned char by default, and can work normally.
But if someone compile it with the option -fsigned-char, the function
can't work correctly.

[PATCH] Revert "iommu/arm-smmu-v3: Decrease the queue size of evtq and priq"
by Zhou Wang
The commit f115f3c0d5d8 decreases evtq and priq, which may lead
evtq/priq to be full with fault events, e.g HiSilicon ZIP/SEC/HPRE have
maximum 1024 queues in one device, every queue could be binded with one
process and trigger a fault event. So let's revert f115f3c0d5d8.
In fact, if an implementation of SMMU really does not need so long evtq
and priq, value of IDR1_EVTQS and IDR1_PRIQS can be set to proper ones.
