One major fix for rt2880-pci in the first patch - fixes breakage that
existed since v4.14.
Other more minor fixes, cleanups, and improvements that either free up

What's new in v2
Special thanks to Jens Axboe for reporting a regression in buffered
I/O and helping test the fix.
This version includes the support of tiers, which represent levels of
usage from file descriptors only. Pages accessed N times via file
descriptors belong to tier
page_memcg_rcu() warns on !rcu_read_lock_held() regardless of
CONFIG_MEMCG. The following code is legit, but it triggers the warning
when !CONFIG_MEMCG, since lock_page_memcg() and unlock_page_memcg()
are empty for this config.
memcg = lock_page_memcg(page1)
(rcu_read_lock() if
cgroup_mutex is needed to synchronize with memcg creations.

Some architectures support the accessed bit on non-leaf PMD entries

mapped, e.g., x86_64 sets the accessed bit on a parent when using it

The aging produces young generations. Given an lruvec, the aging walks
the mm_struct list associated with this lruvec to scan page tables for
referenced pages. Upon finding one, the aging updates the generation
number of this page to max_seq. After each round of scan, the aging
increments max_seq.
For each lruvec, evictable pages are divided into multiple
generations. The youngest generation number is stored in max_seq for
both anon and file types as they are aged on an equal footing. The
oldest generation numbers are stored in min_seq[2] separately for anon
and file types as clean file
The eviction consumes old generations. Given an lruvec, the eviction
scans the pages on the per-zone lists indexed by either of min_seq[2].
It first tries to select a type based on the values of min_seq[2].
When anon and file types are both available from the same generation,
it selects the one
In order to scan page tables, we add an infrastructure to maintain

Multiple threads can concurrently work on the same mm_struct list, and
each of them will be given a different mm_struct.
This infrastructure also tracks whether an

Hi all,
Today's linux-next merge of the akpm-current tree got a conflict in:
lib/test_kasan.c
between commits:
2603f8a78dfb ("kasan: Add KASAN mode kernel parameter")
e80a76aa1a91 ("kasan, arm64: tests supports for HW_TAGS async mode")
from the arm64 tree and commit:

Hi Dmitry,
probably this mail passed under your radar. Can you please add your
statement here.

pci_fixup_irqs() used to call pcibios_map_irq on every PCI device, which
for RT2880 included bus 0 slot 0. After pci_fixup_irqs() got removed,
only slots/funcs with devices attached would be called. While arguably
the right thing, that left no chance for this driver to ever initialize
slot 0,
Mirror commit aeba3731b150 ("powerpc/pci: Fix IO space breakage after
of_pci_range_to_resource() change").
Most MIPS platforms do not define PCI_IOBASE, nor implement
pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0x for most MIPS
platforms. of_pci_range_to_resource passes the _start
Follow the reasoning from commit 842de40d93e0 ("PCI: add generic
pci_enable_resources()"):
The only functional difference from the MIPS version is that the
generic one uses "!r->parent" to check for resource collisions
instead of "!r->start && r->end".
That should have no effect on any

Add a sysfs file /sys/kernel/mm/lru_gen/spread so users can spread

background aging more aggressive.
