f6954245d9 btrfs: remove ref_tree implementation from backref.c
Commit afce772e87 ("btrfs: fix check_shared for fiemap ioctl") added
the ref_tree code in backref.c to reduce backref searching for
shared extents under the FIEMAP ioctl. This code will not be
compatible with the upcoming rbtree changes for improved backref
searching, so this patch removes the ref_tree code.  The rbtree
changes will provide the equivalent functionality for FIEMAP.

The above commit also introduced transaction semantics around calls to
btrfs_check_shared() in order to accurately account for delayed refs.
This functionality needs to be retained, so a complete revert of the
above commit is not desirable. This patch therefore removes the
ref_tree portion of the commit as above, however it does not remove
the transaction portion.

bb739cf08e btrfs: btrfs_check_shared should manage its own transaction
Commit afce772e87 ("btrfs: fix check_shared for fiemap ioctl") added
transaction semantics around calls to btrfs_check_shared() in order to
provide accurate accounting of delayed refs. The transaction management
should be done inside btrfs_check_shared(), so that callers do not need
to manage transactions individually.

e0c476b128 btrfs: backref, cleanup __ namespace abuse
We typically use __ to indicate a helper routine that shouldn't be
called directly without understanding the proper context required
to do so.  We use static functions to indicate that a function is
private to a particular C file.  The backref code uses static
function and __ prefixes on nearly everything, which makes the code
difficult to read and establishes a pattern for future code that
shouldn't be followed.  This patch drops all the unnecessary prefixes.

f148ef4d3a btrfs: Be explicit about usage of min()
__btrfs_alloc_chunk contains code which boils down to:

    ndevs = min(ndevs, devs_max)

It's conditional upon devs_max not being 0. However, it cannot really be 0
since it's always set to either BTRFS_MAX_DEVS_SYS_CHUNK or
BTRFS_MAX_DEVS(fs_info->chunk_root). So eliminate the condition check and use
min explicitly. This has no functional changes.

e19b63cd3c spi: altera: Switch to SPI core transfer queue management
The Altera SPI driver currently uses the spi-bitbang infrastructure for
transfer queue management, but non of the bitbang functionality itself.
This is because when the driver was written this was the only way to not
have to do queue management in the driver itself.

Nowadays transfer queue management is available from the SPI driver core
itself and using the bitbang infrastructure just adds an additional level
of indirection.

Switch the driver over to using the core queue management directly.

24247aeeab x86/intel_rdt/cqm: Improve limbo list processing
During a mkdir, the entire limbo list is synchronously checked on each
package for free RMIDs by sending IPIs. With a large number of RMIDs (SKL
has 192) this creates a intolerable amount of work in IPIs.

Replace the IPI based checking of the limbo list with asynchronous worker
threads on each package which periodically scan the limbo list and move the
RMIDs that have:

	llc_occupancy < threshold_occupancy

on all packages to the free list.

mkdir now returns -ENOSPC if the free list and the limbo list ere empty or
returns -EBUSY if there are RMIDs on the limbo list and the free list is
empty.

Getting rid of the IPIs also simplifies the data structures and the
serialization required for handling the lists.

bbc4615e0b x86/intel_rdt/mbm: Fix MBM overflow handler during CPU hotplug
When a CPU is dying, the overflow worker is canceled and rescheduled on a
different CPU in the same domain. But if the timer is already about to
expire this essentially doubles the interval which might result in a non
detected overflow.

Cancel the overflow worker and reschedule it immediately on a different CPU
in same domain. The work could be flushed as well, but that would
reschedule it on the same CPU.

VSX uses a combination of the old vector registers, the old FP

Thus when we need to see the VSX state in the thread struct
(flush_vsx_to_thread()) or when we'll use the VSX in the kernel
(enable_kernel_vsx()) we need to ensure they are all flushed into
the thread struct if either of them is individually enabled.

Unfortunately we only tested if the whole VSX was enabled, not if they
were individually enabled.

30fec8268c arm64: dts: hi3660: enable idle states
There are two clusters on the Hi3660, the first one is Cortex-A53 based
and the other one is Cortex-A73 based. These two clusters have different
idle states.

Thanks to Daniel Lezcano's recent changes, the generic ARM cpuidle
driver can now support several clusters with different idle states, thus
supporting the big.Little architecture.

In addition to the WFI idle state which is the default shallowest state
for all ARM cpus, the Hi3660 supports the following states:

 - CA53 CPUs:
        - CPU_SLEEP:       CPU power off state
        - CLUSTER_SLEEP_0: Cluster power off state

 - CA73 CPUs:
        - CPU_NAP:         CPU retention state
        - CPU_SLEEP:       CPU power off state
        - CLUSTER_SLEEP_1: Cluster power off state

This patch adds the idle states description for the Hi3660 to the device
tree.

341b26b719 arm64: dts: hi6220: improve g-tx-fifo-size setting for usb device
The current usb device g-tx-fifo-size setting in DT causes two problems
for kernel driver.

1. On hi6220, there are 15 tx_fifo dedicated for all EPs except EP0,
   while DT only provides tx_fifo settings for 6 EPs.  It results in the
   following annoying complaints from kernel.

[    4.451623] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[7]=0
[    4.461303] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[8]=0

[    4.529399] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[15]=0
[    4.539244] dwc2 f72c0000.usb: EPs: 16, dedicated fifos, 1920 entries in SPRAM

   Besides of that, the total 1920 fifo entries isn't fully utilized.
   Endpoint Info Control block consumes 128 entries, g-rx-fifo-size
   is 512, and g-np-tx-fifo-size is 128.  So the fifi entries available
   for tx_fifo is: 1920 - 128 - 512 - 128 = 1152.  Considering that
   the minimal valid tx_fifo size for each EP is 16, it should be
   reasonable to allocate 1152 entries as: 128 x 8 + 16 x 7 = 1136 (only
   16 entries unused).  With this new setting, we can get more EPs to
   use while removing the above warning messages in the meantime.

2. Another consequence of above invalid g_tx_fifo_size parameter is that
   kernel driver will use values read from hardware register as the
   fall-back.  The value is 2048 for each EP fifo.  That's obviously
   invalid either, because even fifo entries for one EP exceeds the
   total entries 1920.  That's why we see the following fat warning from
   function dwc2_hsotg_init_fifo().  The new g-tx-fifo-size settings
   help to remove the warning as well.
