Commit 910f8befdf5b ("xen/pirq: fix error path cleanup when binding
MSIs") fixed a couple of errors in error cleanup path of
xen_bind_pirq_msi_to_irq(). This cleanup allowed a call to
__unbind_from_irq() with an unbound irq, which would result in
triggering the BUG_ON there.
Since there is really no reason for the BUG_ON (xen_free_irq() can
operate on unbound irqs) we can remove it.

When a corrupt inode is detected during xfs_iflush_cluster, we can
get a shutdown ASSERT failure like this:

Essentially, xfs_iflush_abort() has been called twice on the
original inode that that was flushed. This happens because the
inode has been flushed to teh buffer successfully via
xfs_iflush_int(), and so when another inode is detected as corrupt
in xfs_iflush_cluster, the buffer is marked stale and EIO, and
iodone callbacks are run on it.
Running the iodone callbacks walks across the original inode and
calls xfs_iflush_abort() on it. When xfs_iflush_cluster() returns
to xfs_iflush(), it runs the error path for that function, and that
calls xfs_iflush_abort() on the inode a second time, leading to the
above assert failure as the inode is not flush locked anymore.
This bug has been there a long time.
The simple fix would be to just avoid calling xfs_iflush_abort() in
xfs_iflush() if we've got a failure from xfs_iflush_cluster().
However, xfs_iflush_cluster() has magic delwri buffer handling that
means it may or may not have run IO completion on the buffer, and
hence sometimes we have to call xfs_iflush_abort() from
xfs_iflush(), and sometimes we shouldn't.
After reading through all the error paths and the delwri buffer
code, it's clear that the error handling in xfs_iflush_cluster() is
unnecessary. If the buffer is delwri, it leaves it on the delwri
list so that when the delwri list is submitted it sees a shutdown
fliesystem in xfs_buf_submit() and that marks the buffer stale, EIO
and runs IO completion. i.e. exactly what xfs+iflush_cluster() does
when it's not a delwri buffer. Further, marking a buffer stale
clears the _XBF_DELWRI_Q flag on the buffer, which means when
submission of the buffer occurs, it just skips over it and releases
it.
IOWs, the error handling in xfs_iflush_cluster doesn't need to care
if the buffer is already on a the delwri queue or not - it just
needs to mark the buffer stale, EIO and run completions. That means
we can just use the easy fix for xfs_iflush() to avoid the double
abort.

For passing arbitrary data from user land to the Xen hypervisor the
Xen tools today are using mlock()ed buffers. Unfortunately the kernel
might change access rights of such buffers for brief periods of time
e.g. for page migration or compaction, leading to access faults in the
hypervisor, as the hypervisor can't use the locks of the kernel.
In order to solve this problem add a new device node to the Xen privcmd
driver to easily allocate hypercall buffers via mmap(). The memory is
allocated in the kernel and just mapped into user space. Marked as
VM_IO the user mapping will not be subject to page migration et al.

When the inode is in extent format, it can't have more extents that
fit in the inode fork. We don't currenty check this, and so this
corruption goes unnoticed by the inode verifiers. This can lead to
crashes operating on invalid in-memory structures.
Attempts to access such a inode will now error out in the verifier
rather than allowing modification operations to proceed.

Instead of using xfs_bmapi_read to find delalloc extents and then punch
them out using xfs_bunmapi, opencode the loop to iterate over the extents
and call xfs_bmap_del_extent_delay directly. This both simplifies the

On Intel platforms (Skylake and newer), ASPM support in r8169 is the
last missing puzzle to let CPU's Package C-State reaches PC8. Without

Enable or disable ASPM should be done in PCI core instead of in the
device driver.
Commit ba04c7c93bbc ("r8169: disable ASPM") uses
pci_disable_link_state() to disable ASPM, but it's not the best way to
do it. If the device really wants to disable ASPM, we can use a quirk in
PCI core to prevent the PCI core from setting ASPM before probe.
Let's remove pci_disable_link_state() for now. Use PCI core quirks if
any regression happens.

When receiving multiple packets with the same ts ecr value, only try
to compute rcv_rtt sample with the earliest received packet.
This is because the rcv_rtt calculated by later received packets
could possibly include long idle time or other types of delay.
For example:
(1) server sends last packet of reply with TS val V1
(2) client ACKs last packet of reply with TS ecr V1
(3) long idle time passes
(4) client sends next request data packet with TS ecr V1 (again!)
At this time, the rcv_rtt computed on server with TS ecr V1 will be
inflated with the idle time and should get ignored.

Using rht_dereference_bucket() to dereference
->future_tbl looks like a type error, and could be confusing.
Using rht_dereference_rcu() to test a pointer for NULL
adds an unnecessary barrier - rcu_access_pointer() is preferred
for NULL tests when no lock is held.
This uses 3 different ways to access ->future_tbl.
- if we know the mutex is held, use rht_dereference()
- if we don't hold the mutex, and are only testing for NULL,
use rcu_access_pointer()
- otherwise (using RCU protection for true dereference),
use rht_dereference_rcu().
Note that this includes a simplification of the call to
rhashtable_last_table() - we don't do an extra dereference
before the call any more.

Now that we don't use the hash value or shift in nested_table_alloc()
there is room for simplification.
We only need to pass a "is this a leaf" flag to nested_table_alloc(),
and don't need to track as much information in
rht_bucket_nested_insert().
Note there is another minor cleanup in nested_table_alloc() here.
The number of elements in a page of "union nested_tables" is most naturally
PAGE_SIZE / sizeof(ntbl[0])
The previous code had
PAGE_SIZE / sizeof(ntbl[0].bucket)
which happens to be the correct value only because the bucket uses all
the space in the union.

This "feature" is unused, undocumented, and untested and so doesn't
really belong. A patch is under development to properly implement
support for detecting when a search gets diverted down a different
chain, which the common purpose of nulls markers.
This patch actually fixes a bug too. The table resizing allows a
table to grow to 2^31 buckets, but the hash is truncated to 27 bits -
any growth beyond 2^27 is wasteful an ineffective.
This patch results in NULLS_MARKER(0) being used for all chains,

Due to the use of rhashtables in net namespaces,
rhashtable.h is included in lots of the kernel,
so a small changes can required a large recompilation.
This makes development painful.
This patch splits out rhashtable-types.h which just includes
the major type declarations, and does not include (non-trivial)
inline code. rhashtable.h is no longer included by anything

Common include files only include rhashtable-types.h so a large

This fixes using the controller with SDL2.
SDL2 has a naive algorithm to apply the correct settings to a controller.
For X-Box compatible controllers it expects that the controller name
contains a variation of a 'XBOX'-string.
This patch changes the identifier to contain "X-Box" as substring. Tested
with Steam and C-Dogs-SDL which both detect the controller properly after
adding this patch.

Commit 40f7090bb1b4 ("Input: elan_i2c_smbus - fix corrupted stack")
fixed most of the functions using i2c_smbus_read_block_data() to
allocate a buffer with the maximum block size. However three
functions were left unchanged:
* In elan_smbus_initialize(), increase the buffer size in the same
way.
* In elan_smbus_calibrate_result(), the buffer is provided by the
caller (calibrate_store()), so introduce a bounce buffer. Also
name the result buffer size.
* In elan_smbus_get_report(), the buffer is provided by the caller
but happens to be the right length. Add a compile-time assertion
to ensure this remains the case.

The "sector is in requested range" test used to determine whether
sectors should be re-locked or not is done on a variable that is reset
everytime we cross a chip boundary, which can lead to some blocks being
re-locked while the caller expect them to be unlocked.
Fix the check to make sure this cannot happen.

Update the features after calling register_netdev() otherwise the
device features are not set up correctly and it not possible to change
the MTU of the device. After this change, the features reported by
ethtool match the device's features before the commit which introduced
the issue and it is possible to change the device's MTU.

cfi_ppb_unlock() tries to relock all sectors that were locked before
unlocking the whole chip.
This locking used the chip start address + the FULL offset from the
first flash chip, thereby forming an illegal address. Fix that by using
the chip offset(adr).
