Currently registered shrinker is indicated by non-NULL shrinker->nr_deferred.
This approach is fine with nr_deferred at the shrinker level, but the following
patches will move MEMCG_AWARE shrinkers' nr_deferred to memcg level, so their
shrinker->nr_deferred would always be NULL. This would prevent

v6 --> v7:
* Expanded shrinker_info in a batch of BITS_PER_LONG per Kirill.
* Added patch 06/12 to introduce a helper for dereferencing shrinker_info

* Renamed set_nr_deferred_memcg to add_nr_deferred_memcg per Kirill.
* Collected Acked-by from Kirill.
The shrinker map management is not purely memcg specific, it is at the
intersection
between memory cgroup and shrinkers. It's allocation and assignment of a
structure,
and the only memcg bit is the map is being stored in a memcg structure. So

Since memcg_shrinker_map_size just can be changed under holding shrinker_rwsem
exclusively, the read side can be protected by holding read lock, so it sounds
superfluous to have a dedicated mutex.
Kirill Tkhai suggested use write lock since:
* We want the assignment to shrinker_maps is visible
Both memcg_shrinker_map_size and shrinker_nr_max is maintained, but actually the
map size can be calculated via shrinker_nr_max, so it seems unnecessary to keep
both.
Remove memcg_shrinker_map_size since shrinker_nr_max is also used by iterating
the
bit map.

The following patch is going to add nr_deferred into shrinker_map, the change
will
make shrinker_map not only include map anymore, so rename it to
"memcg_shrinker_info".
And this should make the patch adding nr_deferred cleaner and readable and make
review easier. Also remove the "memcg_" prefix
The shrinker_info is dereferenced in a couple of places via
rcu_dereference_protected
with different calling conventions, for example, using mem_cgroup_nodeinfo
helper
or dereferencing memcg->nodeinfo[nid]->shrinker_info. And the later patch
will add more dereference places.
So extract the dere
Currently the number of deferred objects are per shrinker, but some slabs, for
example,
vfs inode/dentry cache are per memcg, this would result in poor isolation among
memcgs.
The deferred objects typically are generated by __GFP_NOFS allocations, one
memcg with
excessive __GFP_NOFS allocations
Use per memcg's nr_deferred for memcg aware shrinkers. The shrinker's
nr_deferred
will be used in the following cases:
1. Non memcg aware shrinkers
2. !CONFIG_MEMCG
3. memcg is disabled by boot parameter

The number of deferred objects might get windup to an absurd number, and it
results in clamp of slab objects. It is undesirable for sustaining workingset.
So shrink deferred objects proportional to priority and cap nr_deferred to twice
of cache items.
The idea is borrowed from Dave Chinner's pat
Now nr_deferred is available on per memcg level for memcg aware shrinkers, so

Update the documentation regarding "nohlt" and indicate that it is not
only for bugs, but can be useful to disable the architecture specific
sleep instructions. ARM, ARM64, SuperH and Microblaze all use
CONFIG_GENERIC_IDLE_POLL_SETUP which takes care of honoring the
"hlt"/"nohlt" parameters.

The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then assigned to a signed 64 bit integer. In the case where
l2nb is 32 or more this can lead to an overflow. Avoid this by shifting
using the BIT_

Registers >= 16 are paged. Be sure to set the page. It seems this was
working for now, because the default is correct for the registers used
in the driver at the moment. But this will also assume, nobody will

The IP101G provides three counters: RX packets, CRC errors and symbol
errors. The error counters can be configured to clear automatically on
read. Unfortunately, this isn't true for the RX packet counter. Because
of this and because the RX packet counter is more likely to overflow,

This bit is reserved as 'always-write-1'. While this is not a particular

Unfortunately, the IP101A and IP101G share the same PHY identifier.
While most of the functions are somewhat backwards compatible, there is
for example the APS_EN bit on the IP101A but on the IP101G this bit

Cleanup the PHY drivers for IPplus devices and add PHY counters and MDIX

Patch 5 adds a model detection based on the behavior of the PHY.
Unfortunately, the IP101A shares the PHY ID with the IP101G. But the latter

At the moment, PORT_MII is reported in the ethtool ops. This is odd
because it is an interface between the MAC and the PHY and no external
port. Some network card drivers will overwrite the port to twisted pair
or fiber, though. Even worse, the MDI/MDIX setting is only used by
ethtool if the port i

There are two functions to flush the per-cpu data of an lruvec into

a CPU disappears during hotplug. The difference is whether all CPUs or
