region before allocating the shared buffer.

GuC log buffer regions for debug-log-events, crash-dumps and
error-state-capture are all part of a single bo allocation that
also includes the guc_log_buffer_state structures. Now that we
support it, increase the size allocation for error-capture.
Since the error-capture region is accessed at non-deterministic
times (as part of GuC triggered context reset) while debug-log-
events region is accessed as part of relay logging or during
debugfs triggered dumps, move the mapping and unmapping of the
shared buffer into intel_guc_log_create and intel_guc_log_destroy
so that it's always mapped throughout life of GuC operation.
Additionally, while here, update the guc log region layout
diagram to follow the order according to the enum definition
as per the GuC interface.
NOTE: A future effort to visit (part of baseline code) is that
buf_addr should be updated to be a io_sys_map and use the
io_sys_map wrapper functions to access the various GuC log
buffer regions.

Update GuC ADS size allocation to include space for
the lists of error state capture register descriptors.
Then, populate GuC ADS with the lists of registers we want
GuC to report back to host on engine reset events. This list
should include global, engine-class and engine-instance
registers for every engine-class type on the current hardware.
Ensure we allocate a persistent store for the register lists
that are populated into ADS so that we don't need to allocate
memory during GT resets when GuC is reloaded and ADS population
happens again.
NOTE: Start with a sample static table of register lists to
layout the framework before adding real registers in subsequent
patch. This static register tables are a different format from
the ADS populated list.

Bug fix:

- fix a potential deadlock between writeback and block plug routines
- fix a deadlock btween freezefs and evict_inode

Before the commit f9ce0be71d ("mm: Cleanup faultaround and finish_fault()
codepaths") there was a call to update_mmu_cache in alloc_set_pte that
used to invalidate TLB entry caching invalid PTE that caused a page
fault. That commit removed that call so now invalid TLB entry survives
causing repetitive page faults on the CPU that took the initial fault
until that TLB entry is occasionally evicted. This issue is spotted by
the xtensa TLB sanity checker.
Fix this issue by defining update_mmu_tlb function that flushes TLB entry
for the faulting address.

This reverts commit 6f98a4bfee.
It turns out we still can't do this. Way too many platforms that don't
have any real source of randomness at boot and no jitter entropy because
they don't even have a cycle counter.
As reported by Guenter Roeck:
"This causes a large number of qemu boot test failures for various
architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I
observed).
Common denominator is that boot hangs at 'Saving random seed:'"
This isn't hugely unexpected - we tried it, it failed, so now we'll
revert it.

Add validation check for JFS_IP(ipimap)->i_imap to prevent a NULL deref
in diFree since diFree uses it without do any validations.
When function jfs_mount calls diMount to initialize fileset inode
allocation map, it can fail and JFS_IP(ipimap)->i_imap won't be
initialized. Then it calls diFreeSpecial to close fileset inode allocation
map inode and it will flow into jfs_evict_inode. Function jfs_evict_inode
just validates JFS_SBI(inode->i_sb)->ipimap, then calls diFree. diFree use
JFS_IP(ipimap)->i_imap directly, then it will cause a NULL deref.

Syzbot reported divide error in dbNextAG(). The problem was in missing
validation check for malicious image.
Syzbot crafted an image with bmp->db_numag equal to 0. There wasn't any
validation checks, but dbNextAG() blindly use bmp->db_numag in divide
expression
Fix it by validating bmp->db_numag in dbMount() and return an error if
image is malicious

In the timer callback function tipc_sk_timeout(), we're trying to
reschedule another timeout to retransmit a setup request if destination
link is congested. But we use the incorrect timeout value
(msecs_to_jiffies(100)) instead of (jiffies + msecs_to_jiffies(100)),
so that the timer expires immediately, it's irrelevant for original
description.
In this commit we correct the timeout value in sk_reset_timer()

Qian Cai reported a boot crash on arm64 systems, caused by:
0fb3978b0a ("sched/numa: Fix NUMA topology for systems with CPU-less nodes")
The bug is that node_state() must be supplied a valid node_states[] array index,
but in task_numa_placement() the max_nid search can fail with NUMA_NO_NODE,
which is not a valid index.
Fix it by checking that max_nid is a valid index.

The LAN966x has two internal PHYs which are in reset by default. The
driver already supported the internal PHYs of the SparX-5. Now add
support for the LAN966x, too. Add a new compatible to distinguish them.
The LAN966x has additional control bits in this register, thus convert
the regmap_write() to regmap_update_bits() to leave the remaining bits
untouched. This doesn't change anything for the SparX-5 SoC, because
there, the register consists only of reset bits.
