UPSTREAM: USB: don't free bandwidth_mutex too early
The USB core contains a bug that can show up when a USB-3 host
controller is removed. If the primary (USB-2) hcd structure is
released before the shared (USB-3) hcd, the core will try to do a
double-free of the common bandwidth_mutex.
The problem was described in graphical form by Chung-Geol Kim, who
first reported it:

|__________________|
=================================================
This happens because hcd_release() frees the bandwidth_mutex whenever
it sees a primary hcd being released (which is not a very good idea
in any case), but in the course of releasing the primary hcd, it
changes the pointers in the shared hcd in such a way that the shared
hcd will appear to be primary when it gets released.
This patch fixes the problem by changing hcd_release() so that it
deallocates the bandwidth_mutex only when the _last_ hcd structure
referencing it is released. The patch also removes an unnecessary
test, so that when an hcd is released, both the shared_hcd and
primary_hcd pointers in the hcd's peer will be cleared.

The XHCI controller presents two USB buses to the system - one for USB2

hub_port_init
hub_set_address
xhci_address_device
xhci_setup_device
Mathias Nyman explains the current behaviour violates the XHCI spec:
hub_port_reset() will end up moving the corresponding xhci device slot
to default state.
As hub_port_reset() is called several times in hub_port_init() it
sounds reasonable that we could end up with two threads having their
xhci device slots in default state at the same time, which according to
xhci 4.5.3 specs still is a big no no:
"Note: Software shall not transition more than one Device Slot to the
Default State at a time"
So both threads fail at their next task after this.
One fails to read the descriptor, and the other fails addressing the
device.
Fix this in hub_port_init by locking the USB controller (instead of an
individual bus) to prevent simultaneous initialisation of both buses.

Add resource managed version (devm_*) of these APIs so that if client

it can be done by managed device framework when driver get un-binded.
This reduces the code in error path and also need of .remove callback in

UPSTREAM: PCI: rockchip: Disable RC's ASPM L0s based on DT "aspm-no-l0s"
Rockchip's RC produces a 100MHz reference clock but there are two
methods for the PHY to generate it:
(1) Use the system PLL to generate a 100MHz clock. The PHY will relock
it, filter signal noise, and output the reference clock. ASPM L0s
works correctly, but circuit noise issues make it difficult to pass
the TX compatibility test.
(2) Share the SoC's 24MHZ crystal oscillator with the PHY and force the
PHY's PLL to generate 100MHz internally. In this case, exit from
ASPM L0s sometimes fails due to a design error in the RC receiver
circuit. Even if we use extended-synch, the PHY sometimes fails to
relock the bits from FTS, which will hang the system.
We want the flexibility to use both clocking methods, so add a DT
property, "aspm-no-l0s". If that's present, disable L0s to avoid the
issues with case (2).

net: mvpp2: fix dma unmapping of TX buffers for fragments
commit
8354491c9d5b06709384cea91d13019bf5e61449 upstream.
Since commit
71ce391dfb784 ("net: mvpp2: enable proper per-CPU TX
buffers unmapping"), we are not correctly DMA unmapping TX buffers for
fragments.
Indeed, the mvpp2_txq_inc_put() function only stores in the
txq_cpu->tx_buffs[] array the physical address of the buffer to be
DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use
skb_headlen(skb) to get the size to be unmapped. Both of this works fine
for TX descriptors that are associated directly to a SKB, but not the
ones that are used for fragments, with a NULL pointer as skb:
- We have a NULL physical address when calling DMA unmap
- skb_headlen(skb) crashes because skb is NULL
This causes random crashes when fragments are used.
To solve this problem, we need to:
- Store the physical address of the buffer to be unmapped
unconditionally, regardless of whether it is tied to a SKB or not.
- Store the length of the buffer to be unmapped, which requires a new
field.
Instead of adding a third array to store the length of the buffer to be
unmapped, and as suggested by David Miller, this commit refactors the
tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a
separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is
added. Therefore, instead of having three arrays to allocate/free, we
have a single one, which also improve data locality, reducing the
impact on the CPU cache.

kconfig/nconf: Fix hang when editing symbol with a long prompt
commit
79e51b5c2deea542b3bb8c66e0d502230b017dde upstream.
Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters. dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid. It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.
The additions in the offset calculations also don't match the intended
size of the window.
Limit the window size and calculate the offset similarly to
show_scroll_win().

powerpc: Convert cmp to cmpd in idle enter sequence
commit
80f23935cadb1c654e81951f5a8b7ceae0acc1b4 upstream.
PowerPC's "cmp" instruction has four operands. Normally people write
"cmpw" or "cmpd" for the second cmp operand 0 or 1. But, frequently
people forget, and write "cmp" with just three operands.
With older binutils this is silently accepted as if this was "cmpw",
while often "cmpd" is wanted. With newer binutils GAS will complain
about this for 64-bit code. For 32-bit code it still silently assumes
"cmpw" is what is meant.
In this instance the code comes directly from ISA v2.07, including the
cmp, but cmpd is correct. Backport to stable so that new toolchains can
build old kernels.
