The only thing that prevents building this driver on other
platforms is the mach/hardware.h include, which is not actually
used here at all, so remove the line and allow CONFIG_COMPILE_TEST.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>

expression ret;
struct platform_device *E;

ret =

platform_get_irq(E, ...)

platform_get_irq_byname(E, ...)

While we're here, remove braces on if statements that only have one

Pull preemption Kconfig fix from Thomas Gleixner:
"The PREEMPT_RT stub config renamed PREEMPT to PREEMPT_LL and defined
PREEMPT outside of the menu and made it selectable by both PREEMPT_LL
and PREEMPT_RT.
Stupid me missed that 114 defconfigs select CONFIG_PREEMPT which
obviously can't work anymore. oldconfig builds are affected as well,
but it's more obvious as the user gets asked. [old]defconfig silently
fixes it up and selects PREEMPT_NONE.
Unbreak it by undoing the rename and adding a intermediate config
symbol which is selected by both PREEMPT and PREEMPT_RT. That requires
to chase down a few #ifdefs, but it's better than tweaking 114
defconfigs and annoying users"

The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to
CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y
set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on
the preemption mode choice wich defaults to NONE. This also affects
oldconfig builds.
So rather than changing 114 defconfig files and being an annoyance to
users, revert the rename and select a new config symbol PREEMPTION. That
keeps everything working smoothly and the revelant ifdef's are going to be
fixed up step by step.

There is a race between reading task->exit_state in pidfd_poll and
writing it after do_notify_parent calls do_notify_pidfd. Expected
sequence of events is:
CPU 0 CPU 1
------------------------------------------------
exit_notify
do_notify_parent
do_notify_pidfd
tsk->exit_state = EXIT_DEAD
pidfd_poll
if (tsk->exit_state)
However nothing prevents the following sequence:
CPU 0 CPU 1
------------------------------------------------
exit_notify
do_notify_parent
do_notify_pidfd
pidfd_poll
if (tsk->exit_state)
tsk->exit_state = EXIT_DEAD
This causes a polling task to wait forever, since poll blocks because
exit_state is 0 and the waiting task is not notified again. A stress
test continuously doing pidfd poll and process exits uncovered this bug.
To fix it, we make sure that the task's exit_state is always set before
calling do_notify_pidfd.

Some applications set tiny SO_SNDBUF values and expect
TCP to just work. Recent patches to address CVE-2019-11478
broke them in case of losses, since retransmits might
be prevented.
We should allow these flows to make progress.
This patch allows the first and last skb in retransmit queue
to be split even if memory limits are hit.
It also adds the some room due to the fact that tcp_sendmsg()
and tcp_sendpage() might overshoot sk_wmem_queued by about one full
TSO skb (64KB size). Note this allowance was already present
in stable backports for kernels < 4.15
Note for < 4.15 backports :
tcp_rtx_queue_tail() will probably look like :
static inline struct sk_buff *tcp_rtx_queue_tail(const struct sock *sk)
{
struct sk_buff *skb = tcp_send_head(sk);
return skb ? tcp_write_queue_prev(sk, skb) : tcp_write_queue_tail(sk);
}

vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing
using ip/ipv6 addresses, but don't make sure the header is available
in skb->data[] (skb_headlen() is less then header size).
Case:
1) igb driver from intel.
2) Packet size is greater then 255.
3) MPLS forwards to VRF device.
So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound()
functions.

As pointed out by Firo Yang, a netdev tx timeout may trigger just before an
ethtool set_channels operation is started. be_tx_timeout(), which dumps
some queue structures, is not written to run concurrently with
be_update_queues(), which frees/allocates those queues structures. Add some
synchronization between the two.

The commit b3aa14f02254 ("iommu: remove the mapping_error dma_map_ops
method") incorrectly changed the checking from dma_ops_alloc_iova() in
map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
never return DMA_MAPPING_ERROR on failure but 0, so the error handling
is all wrong.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.
The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.
