9dfa9a5c9b perf/x86: Reduce stack usage for x86_pmu::drain_pebs()
intel_pmu_drain_pebs_*() is typically called from handle_pmi_common(),
both have an on-stack struct perf_sample_data, which is *big*. Rewire
things so that drain_pebs() can use the one handle_pmi_common() has.

267fb27352 perf: Reduce stack usage of perf_output_begin()
__perf_output_begin() has an on-stack struct perf_sample_data in the
unlikely case it needs to generate a LOST record. However, every call
to perf_output_begin() must already have a perf_sample_data on-stack.

7bdb157cde perf/core: Fix a memory leak in perf_event_parse_addr_filter()
As shown through runtime testing, the "filename" allocation is not
always freed in perf_event_parse_addr_filter().

There are three possible ways that this could happen:

 - It could be allocated twice on subsequent iterations through the loop,
 - or leaked on the success path,
 - or on the failure path.

Clean up the code flow to make it obvious that 'filename' is always
freed in the reallocation path and in the two return paths as well.

We rely on the fact that kfree(NULL) is NOP and filename is initialized
with NULL.

This fixes the leak. No other side effects expected.

[ Dan Carpenter: cleaned up the code flow & added a changelog. ]
[ Ingo Molnar: updated the changelog some more. ]

Fixes: 375637bc52 ("perf/core: Introduce address range filtering")

659caaf65d A fix for a potential stall on umount caused by the MDS dropping
our REQUEST_CLOSE message.  The code that handled this case was
 inadvertently disabled in 5.9, this patch removes it entirely and
 fixes the problem in a way that is consistent with ceph-fuse.

  Changes all over the place, the amdgpu changes contain support for a

8ffd778aff tpm: efi: Don't create binary_bios_measurements file for an empty log
Mimic the pre-existing ACPI and Device Tree event log behavior by not
creating the binary_bios_measurements file when the EFI TPM event log is
empty.

This fixes the following NULL pointer dereference that can occur when
reading /sys/kernel/security/tpm0/binary_bios_measurements after the
kernel received an empty event log from the firmware:

In this situation, the bios_event_log pointer in the tpm_bios_log struct
was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. This was
due to the following kmemdup() in tpm_read_log_efi():

int tpm_read_log_efi(struct tpm_chip *chip)
{
...
	/* malloc EventLog space */
	log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL);
	if (!log->bios_event_log) {
		ret = -ENOMEM;
		goto out;
	}
...
}

When log_size is zero, due to an empty event log from firmware,
ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the
binary_bios_measurements file, the tpm2_bios_measurements_start()
function does not perform a ZERO_OR_NULL_PTR() check on the
bios_event_log pointer before dereferencing it.

Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of
the bios_event_log pointer, simply avoid creating the
binary_bios_measurements_file as is done in other event log retrieval
backends.

Explicitly ignore all of the events in the final event log when the main
event log is empty. The list of events in the final event log cannot be
accurately parsed without referring to the first event in the main event
log (the event log header) so the final event log is useless in such a
situation.

b154ce11ea tpm_tis: Disable interrupts on ThinkPad T490s
There is a misconfiguration in the bios of the gpio pin used for the
interrupt in the T490s. When interrupts are enabled in the tpm_tis
driver code this results in an interrupt storm. This was initially
reported when we attempted to enable the interrupt code in the tpm_tis
driver, which previously wasn't setting a flag to enable it. Due to
the reports of the interrupt storm that code was reverted and we went back
to polling instead of using interrupts. Now that we know the T490s problem
is a firmware issue, add code to check if the system is a T490s and
disable interrupts if that is the case. This will allow us to enable
interrupts for everyone else. If the user has a fixed bios they can
force the enabling of interrupts with tpm_tis.interrupts=1 on the
kernel command line.

Network problems with RTL8125B have been reported [0] and with help
from Realtek it turned out that this chip version has a hw problem
with short packets (similar to RTL8168evl). Having said that activate
the same workaround as for RTL8168evl.
Realtek suggested to activate the workaround for RTL8125A too, even
though they're not 100% sure yet which RTL8125 versions are affected.

62575e270f ceph: check session state after bumping session->s_seq
Some messages sent by the MDS entail a session sequence number
increment, and the MDS will drop certain types of requests on the floor
when the sequence numbers don't match.

In particular, a REQUEST_CLOSE message can cross with one of the
sequence morphing messages from the MDS which can cause the client to
stall, waiting for a response that will never come.

Originally, this meant an up to 5s delay before the recurring workqueue
job kicked in and resent the request, but a recent change made it so
that the client would never resend, causing a 60s stall unmounting and
sometimes a blockisting event.

Add a new helper for incrementing the session sequence and then testing
to see whether a REQUEST_CLOSE needs to be resent, and move the handling
of CEPH_MDS_SESSION_CLOSING into that function. Change all of the
bare sequence counter increments to use the new helper.

Reorganize check_session_state with a switch statement.  It should no
longer be called when the session is CLOSING, so throw a warning if it
ever is (but still handle that case sanely).

832ea23427 PCI: mvebu: Fix duplicate resource requests
With commit 669cbc7081 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated
into resources when the host bridge is allocated. The resources are
requested as well, but that happens a second time for the mvebu driver in
mvebu_pcie_parse_request_resources(). We should only be requesting the
additional resources added in mvebu_pcie_parse_request_resources().  These
are not added by default because they use custom properties rather than
standard DT address translation.

Also, the bus ranges was also populated by default, so we can remove it
from mvebu_pci_host_probe().

9fff3256f9 PCI: dwc: Restore ATU memory resource setup to use last entry
Prior to commit 0f71c60ffd ("PCI: dwc: Remove storing of PCI resources"),
the DWC driver was setting up the last memory resource rather than the
first memory resource. This doesn't matter for most platforms which only
have 1 memory resource, but it broke Tegra194 which has a 2nd
(prefetchable) memory region that requires an ATU entry. The first region
on Tegra194 relies on the default 1:1 pass-thru of outbound transactions
and doesn't need an ATU entry.
