Once flow cache is removed the implicit interrupt.h inclusion goes away
which will break the build.

net: dsa: mv88e6xxx: cleanup capabilities
This patch series removes the remaining capabilities as well as the
flags bitmap in the info structures. Most of them are turned into ops,
or new info members.
There is no mv88e6xxx_cap enum or bitmap flags anymore, only
mv88e6xxx_info and mv88e6xxx_ops structures.
While reviewing and documenting the related G2 registers, fix a few
inconsistencies: 88E6185 has no interrupt in G2 and 88E6390 has a POT.
Except these two adjustments, there is no functional changes.

Instead of relying on a bitmap flag, add a new multi_chip info flag to
describe the presence of the indirect SMI access though the two device
registers 0x0 and 0x1.
All remaining capabilities and flags are now unused. Remove the
mv88e6xxx_cap enum and the info flags bitmaps.

The 88E6352 family supports Energy Detect and has one bit for Sense and
one bit for periodically transmit NLP (Energy Detect+TM). The 88E6390
family adds another bit to distinguish Auto or SW wake-up. Chips
supporting EEE all have an EEE Enabled bit in the Port Status Register.
This patch adds new ops for the PHY Energy Detect accesses.

When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
set, DIR1 is expected to have SGID bit set (and owning group equal to
the owning group of 'DIR0'). However when 'DIR0' also has some default
ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
'DIR1' to get cleared if user is not member of the owning group.
Fix the problem by creating __hfsplus_set_posix_acl() function that does
not call posix_acl_update_mode() and use it when inheriting ACLs. That
prevents SGID bit clearing and the mode has been properly set by
posix_acl_create() anyway.

When changing a file's acl mask, reiserfs_set_acl() will first set the

actual extended attribute representing the new acl.
If the second part fails (due to lack of space, for example) and the
file had no acl attribute to begin with, the system will from now on
assume that the mask permission bits are actual group permission bits,
potentially granting access to the wrong users.
Prevent this by only changing the inode mode after the acl has been set.

This happens when the QP is in IB_QPS_RESET state and the stack
is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop().
According to the IB spec, Table 91 - "QP State Transition Properties"
it looks like the transition from reset to error is valid:
Transition: Any State to Error

Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs
according to the netdev events.
The ib_wq isn't an ordered workqueue and thus two work elements can be executed
concurrently which will result in unexpected behavior and inconsistency of the
GIDs cache content.
Example:
ifconfig eth1 11.11.11.11/16 up
This command will invoke the following netdev events in the following order:
1. NETDEV_UP
2. NETDEV_DOWN
3. NETDEV_UP
If (2) and (3) will be executed concurrently or in reverse order, instead of
having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.

Commit 21caf2fc19 ("mm: teach mm by current context info to not do I/O
during memory allocation") added the memalloc_noio_(save|restore) functions
to enable people to modify the MM behavior by disabling I/O during memory
allocation. This was further extended in Fixes: 934f3072c1 ("mm: clear
__GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent
allocation paths recursing back into the filesystem without explicitly
changing the flags for every allocation site.
However the IPoIB hasn't been keeping up with the changes and missed
completely these memalloc_noio_* calls. This led to update of
allocation site with special QP creation flag, see commit 09b93088d7
("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this
flag is supported by small number of drivers in IB stack.
Let's change it by updating to memalloc_noio_* calls and allow
for every driver underneath enjoy NOIO allocations.
