9286ac4829 ARM: STi: DT: STiH407: Add dt nodes for sdhci and emmc.
The nodes have been split to allow as much commonality as possible.
The stih407 has a silicon bug with eMMC UHS modes (with top regs)
and as such doesn't have any of the uhs dt properties.

68fc378ce3 Revert "powerpc/tm: Abort syscalls in active transactions"
This reverts commit feba40362b.

Although the principle of this change is good, the implementation has a
few issues.

Firstly we can sometimes fail to abort a syscall because r12 may have
been clobbered by C code if we went down the virtual CPU accounting
path, or if syscall tracing was enabled.

Secondly we have decided that it is safer to abort the syscall even
earlier in the syscall entry path, so that we avoid the syscall tracing
path when we are transactional.

So that we have time to thoroughly test those changes we have decided to
revert this for this merge window and will merge the fixed version in
the next window.

NB. Rather than reverting the selftest we just drop tm-syscall from
TEST_PROGS so that it's not run by default.

a2698a9bf9 Bluetooth: btusb: Add Realtek 8723A/8723B/8761A/8821A support
Realtek ship a variety of bluetooth USB devices that identify
themselves with standard USB Bluetooth device class values, but
require a special driver to actually work. Without that driver,
you never get any scan results.

More recently however, Realtek appear to have wisened up and simply
posted a firmware update that makes these devices comply with
normal btusb protocols. The firmware needs to be uploaded on each boot.

Based on Realtek code from https://github.com/lwfinger/rtl8723au_bt
('new' branch).

This enables bluetooth support in the Gigabyte Brix GB-BXBT-2807 which
has this RTL8723BE USB device:

There is no change to the USB descriptor after firmware update,
however the version read by HCI_OP_READ_LOCAL_VERSION changes from
0x8723 to 0x3083.

This has also been tested on RTL8723AE and RTL8821AE. Support for
RTL8761A has also been added, but that is untested.

483d821108 gpio: sysfs: fix memory leaks and device hotplug
Unregister GPIOs requested through sysfs at chip remove to avoid leaking
the associated memory and sysfs entries.

The stale sysfs entries prevented the gpio numbers from being exported
when the gpio range was later reused (e.g. at device reconnect).

This also fixes the related module-reference leak.

Note that kernfs makes sure that any on-going sysfs operations finish
before the class devices are unregistered and that further accesses
fail.

The chip exported flag is used to prevent gpiod exports during removal.
This also makes it harder to trigger, but does not fix, the related race
between gpiochip_remove and export_store, which is really a race with
gpiod_request that needs to be addressed separately.

Also note that this would prevent the crashes (e.g. NULL-dereferences)
at reconnect that affects pre-3.18 kernels, as well as use-after-free on
operations on open attribute files on pre-3.14 kernels (prior to
kernfs).

6e9250f59e tcp: add TCP_CC_INFO socket option
Some Congestion Control modules can provide per flow information,
but current way to get this information is to use netlink.

Like TCP_INFO, let's add TCP_CC_INFO so that applications can
issue a getsockopt() if they have a socket file descriptor,
instead of playing complex netlink games.

Sample usage would be :

  union tcp_cc_info info;
  socklen_t len = sizeof(info);

  if (getsockopt(fd, SOL_TCP, TCP_CC_INFO, &info, &len) == -1)

The following script is used to import dtc upstream

this commit it will include the same.

Also, currently in arch and driver code that needs early access to
the flattened device tree it is necessary to add specific CFLAGS
so that when scripts/dtc/libfdt/libfdt.h is included the C
preprocessor is able to locate the libfdt versions of libfdt_env.h
and fdt.h without generating an error. So, this script replaces
angular brackets with quotation used to include header files

5d2361db48 Btrfs: btrfs_release_extent_buffer_page didn't free pages of dummy extent
btrfs_release_extent_buffer_page() can't handle dummy extent that
allocated by btrfs_clone_extent_buffer() properly. That is because
reference count of pages that allocated by btrfs_clone_extent_buffer()
was 2, 1 by alloc_page(), and another by attach_extent_buffer_page().

Running following command repeatly can check this memory leak problem

    btrfs inspect-internal inode-resolve 256 /mnt/btrfs

As dwc2 pci module is now exporting dwc2 platform device, include
platform.o in dwc2-y and remove USB_DWC2_PLATFORM configuration
option. Driver will be built as two modules, dwc2.ko and dwc2_pci.ko.
dwc2.ko is the new platform driver.

Remove all EXPORT_SYMBOL_GPL as they are not needed any more.

33ad261aa6 usb: dwc2: host: spinlock urb_enqueue
During urb_enqueue, if the urb can't be queued to the endpoint,
the urb is freed without any spinlock protection.
This leads to memory corruption when concurrent urb_dequeue try to free
same urb->hcpriv.
Thus, ensure the whole urb_enqueue in spinlocked.

18b2b37c59 usb: dwc2: gadget: powerup controller if needed
During vbus session, usb controller needs to exit hibernation if it was
previously in suspend state.
Since controller will be resetted and configured, there is no need
to restore registers.

Moreover, set lx_state to L0 on B session. vbus_session callback may
not be used by all platforms. Thus, controller software state needs
to be set to L0 if the controller detects a valid B session.
Otherwise, lx_state will remain L2 and prevent any request submission.
