- Fix use of event length in validation of persistent ring buffer

valid by several methods. One being to walk all the events in the
memory location to make sure they are all valid. The length of the
event is used to move to the next event. This length is determined by
the data in the buffer. If that length is corrupted, it could
possibly make the next event to check located at a bad memory

PCI: dwc: ep: Return after clearing BAR-match inbound mapping
dw_pcie_ep_clear_ib_maps() first checks whether the inbound mapping for a
BAR is in BAR Match Mode (tracked via ep_func->bar_to_atu[bar]). Once
found, the iATU region is disabled and the bookkeeping is cleared.
BAR Match Mode and Address Match Mode mappings are mutually exclusive for a
given BAR, so there is nothing left for the Address Match Mode teardown
path to do after the BAR Match Mode mapping has been removed.
Return early after clearing the BAR Match Mode mapping to avoid running the
Address Match Mode teardown path. This makes the helper's intention
explicit and helps detect incorrect use of pci_epc_set_bar().

PCI: dwc: ep: Always clear IB maps on BAR update
dw_pcie_ep_set_bar() currently tears down existing inbound mappings only
when either the previous or the new struct pci_epf_bar uses submaps
(num_submap != 0). If both the old and new mappings are BAR Match Mode,
reprogramming the same ATU index is sufficient, so no explicit teardown
was needed.
However, some callers may reuse the same struct pci_epf_bar instance and
update it in place before calling set_bar() again. In that case
ep_func->epf_bar[bar] and the passed-in epf_bar can point to the same
object, so we cannot reliably distinguish BAR Match Mode -> BAR Match Mode
from Address Match Mode -> BAR Match Mode. As a result, the conditional
teardown based on num_submap becomes unreliable and existing inbound maps
may be left active.
Call dw_pcie_ep_clear_ib_maps() unconditionally before reprogramming the
BAR so that in-place updates are handled correctly.

PCI: Account fully optional bridge windows correctly
pbus_size_mem_optional() adds dev_res->add_size of a bridge window into
children_add_size when the window has a non-optional part. However, if the
bridge window is fully optional, only r_size is added (which is zero for
such a window).
Also, a second dev_res entry will be added by pci_dev_res_add_to_list()
into realloc_head for the bridge window (resulting in triggering the
realloc_head-must-be-fully-consumed sanity check after a single pass of the
resource assignment algorithm):
WARNING: drivers/pci/setup-bus.c:2153 at pci_assign_unassigned_root_bus_resources+0xa5/0x260
Correct these problems by always adding dev_res->add_size for bridge
windows and not calling pci_dev_res_add_to_list() if the dev_res entry
exists.

tracing: Wake up poll waiters for hist files when removing an event
The event_hist_poll() function attempts to verify whether an event file is
being removed, but this check may not occur or could be unnecessarily
delayed. This happens because hist_poll_wakeup() is currently invoked only
from event_hist_trigger() when a hist command is triggered. If the event
file is being removed, no associated hist command will be triggered and a
waiter will be woken up only after an unrelated hist command is triggered.
Fix the issue by adding a call to hist_poll_wakeup() in
remove_event_file_dir() after setting the EVENT_FILE_FL_FREED flag. This
ensures that a task polling on a hist file is woken up and receives
EPOLLERR.

tracing: Fix checking of freed trace_event_file for hist files
The event_hist_open() and event_hist_poll() functions currently retrieve
a trace_event_file pointer from a file struct by invoking
event_file_data(), which simply returns file->f_inode->i_private. The
functions then check if the pointer is NULL to determine whether the event
is still valid. This approach is flawed because i_private is assigned when
an eventfs inode is allocated and remains set throughout its lifetime.
Instead, the code should call event_file_file(), which checks for
EVENT_FILE_FL_FREED. Using the incorrect access function may result in the
code potentially opening a hist file for an event that is being removed or
becoming stuck while polling on this file.
Correct the access method to event_file_file() in both functions.
