A reset failure schedules the device to unbind from the driver through
the pci driver's remove. This cleans up all intialization, so there is
no need to duplicate the potentially racy cleanup.
To help understand why a reset failed, the status is logged with the
existing warning message.

This patch makes nvme namespace removal lockless. It is up to the caller
to ensure no active namespace scanning is occuring. To ensure no scan
work occurs, the nvme pci driver adds a removing state to the controller
device to avoid queueing scan work during removal. The work is flushed
after setting the state, so no new scan work can be queued.
The lockless removal allows the driver to cleanup a namespace
request_queue if the controller fails during removal. Previously this
could deadlock trying to acquire the namespace mutex in order to handle
such events.

A namespace may be detached from a controller, but a user may be holding
a reference to it. Attaching a new namespace with the same NSID will create
duplicate names when using the NSID to name the disk.
This patch uses an IDA that is released only when the last reference is
released instead of using the namespace ID.

The bio passed to bio_will_gap() may be fast cloned from upper
layer(dm, md, bcache, fs, ...), or from bio splitting in block
core.
Unfortunately bio_will_gap() just figures out the last bvec via
'bi_io_vec[prev->bi_vcnt - 1]' directly, and this way is obviously
wrong.
This patch introduces two helpers for getting the first and last
bvec of one bio for fixing the issue.

The argument structs are used in arrays for G_TOPOLOGY IOCTL. The
arguments themselves do not need to be aligned to a power of two, but
aligning them up to the largest basic type alignment (u64) on common ABIs
is a good thing to do.
The patch changes the size of the reserved fields to 5 or 6 u32's and
aligns the size of the struct to 8 bytes so we do no longer depend on the
compiler to perform the alignment.
While at it, add __attribute__ ((packed)) to these structs as well.

Currently, the inlen field of the vendor's part of the command
doesn't match the command buffer. This happens because the inlen
accommodates ib_uverbs_cmd_hdr which is deducted from the in buffer.
This is problematic since the vendor function could be called either
from the legacy verb (where the input length mismatches the actual
length) or by the extended verb (where the length matches). The vendor
has no idea which function calls it and therefore has no way to know
how the length variable should be treated.
Fixing this by aligning the inlen to the correct length.
All vendor drivers either assumed that inlen >= sizeof(vendor_uhw_cmd)
or just failed wrongly (mlx5) and fixed in this patch.

When destroying a hw_breakpoint event, the kernel oopses as follows:

LR [c00000000020b6b4] release_bp_slot+0x44/0x80

hw_breakpoint_event_init()
bp->destroy = bp_perf_event_destroy;
do_exit()
perf_event_exit_task()
perf_event_exit_task_context()
WRITE_ONCE(child_ctx->task, TASK_TOMBSTONE);
perf_event_exit_event()
free_event()
_free_event()
bp_perf_event_destroy() // event->destroy(event);
release_bp_slot()
arch_unregister_hw_breakpoint()
perf_event_exit_task_context() sets child_ctx->task as TASK_TOMBSTONE
which is (void *)-1. arch_unregister_hw_breakpoint() tries to fetch
'thread' attribute of 'task' resulting in oops.
Peterz points out that the code shouldn't be using bp->ctx anyway, but
fixing that will require a decent amount of rework. So for now to fix
the oops, check if bp->ctx->task has been set to (void *)-1, before
dereferencing it. We don't use TASK_TOMBSTONE, because that would
require exporting it and it's supposed to be an internal detail.

The exit path will do some final updates to the VM of an exiting process
to inform others of the fact that the process is going away.
That happens, for example, for robust futex state cleanup, but also if
the parent has asked for a TID update when the process exits (we clear
the child tid field in user space).
However, at the time we do those final VM accesses, we've already
stopped accepting signals, so the usual "stop waiting for userfaults on
signal" code in fs/userfaultfd.c no longer works, and the process can
become an unkillable zombie waiting for something that will never
happen.
To solve this, just make handle_userfault() abort any user fault
handling if we're already in the exit path past the signal handling
state being dead (marked by PF_EXITING).
This VM special case is pretty ugly, and it is possible that we should
look at finalizing signals later (or move the VM final accesses
earlier). But in the meantime this is a fairly minimally intrusive fix.

In amdgpu_connector_hotplug(), we need to start DP link
training only after we have received DPCD. The function
amdgpu_atombios_dp_get_dpcd() returns non-zero value only
when an error condition is met, otherwise returns zero.
So in case the function encounters an error, we need to
skip rest of the code and return from amdgpu_connector_hotplug()
immediately. Only when we are successfull in reading DPCD
pin, we should carry on with turning-on the monitor.
