On link state change, the controller gets reset,
causing PPS to drop out and the PHC to lose its
time and calibration. So we restart it if needed,
restoring calibration and time registers.
Changes since v2:
* Add `fec_ptp_save_state()`/`fec_ptp_restore_state()`
* Use `ktime_get_real_ns()`
* Use `BIT()` macro
Changes since v1:
* More ECR #define's

When running identity-mapped and depending on the kernel configuration,
it is possible that the compiler uses jump tables when generating code
for cc_platform_has().
This causes a boot failure because the jump table uses un-mapped kernel
virtual addresses, not identity-mapped addresses. This has been seen
with CONFIG_RETPOLINE=n.
Similar to sme_encrypt_kernel(), use an open-coded direct check for the
status of SNP rather than trying to eliminate the jump table. This
preserves any code optimization in cc_platform_has() that can be useful
post boot. It also limits the changes to SEV-specific files so that
future compiler features won't necessarily require possible build changes
just because they are not compatible with running identity-mapped.

In some cases, bootloaders will leave boot_params->cc_blob_address
uninitialized rather than zeroing it out. This field is only meant to be
set by the boot/compressed kernel in order to pass information to the
uncompressed kernel when SEV-SNP support is enabled.
Therefore, there are no cases where the bootloader-provided values
should be treated as anything other than garbage. Otherwise, the
uncompressed kernel may attempt to access this bogus address, leading to
a crash during early boot.
Normally, sanitize_boot_params() would be used to clear out such fields
but that happens too late: sev_enable() may have already initialized
it to a valid value that should not be zeroed out. Instead, have
sev_enable() zero it out unconditionally beforehand.
Also ensure this happens for !CONFIG_AMD_MEM_ENCRYPT as well by also
including this handling in the sev_enable() stub function.

Currently, net.netfilter.nf_conntrack_frag6_high_thresh can only be lowered.
I found this issue while investigating a probable kernel issue
causing flakes in tools/testing/selftests/net/ip_defrag.sh
In particular, these sysctl changes were ignored:
ip netns exec "${NETNS}" sysctl -w net.netfilter.nf_conntrack_frag6_high_thresh=9000000 >/dev/null 2>&1
ip netns exec "${NETNS}" sysctl -w net.netfilter.nf_conntrack_frag6_low_thresh=7000000 >/dev/null 2>&1
This change is inline with commit 836196239298 ("net/ipfrag: let ip[6]frag_high_thresh

To clear the flow table on flow table free, the following sequence
normally happens in order:
1) gc_step work is stopped to disable any further stats/del requests.
2) All flow table entries are set to teardown state.
3) Run gc_step which will queue HW del work for each flow table entry.
4) Waiting for the above del work to finish (flush).
5) Run gc_step again, deleting all entries from the flow table.
6) Flow table is freed.
But if a flow table entry already has pending HW stats or HW add work
step 3 will not queue HW del work (it will be skipped), step 4 will wait
for the pending add/stats to finish, and step 5 will queue HW del work
which might execute after freeing of the flow table.
To fix the above, this patch flushes the pending work, then it sets the
teardown flag to all flows in the flowtable and it forces a garbage
collector run to queue work to remove the flows from hardware, then it
flushes this new pending work and (finally) it forces another garbage
collector run to remove the entry from the software flowtable.

Pull file_remove_privs() fix from Christian Brauner:
"As part of Stefan's and Jens' work to add async buffered write
support to xfs we refactored file_remove_privs() and added
__file_remove_privs() to avoid calling __remove_privs() when
IOCB_NOWAIT is passed.
While debugging a recent performance regression report I found that
during review we missed that commit faf99b563558 ("fs: add
__remove_file_privs() with flags parameter") accidently changed
behavior when dentry_needs_remove_privs() returns zero.
Before the commit it would still call inode_has_no_xattr() setting
the S_NOSEC bit and thereby avoiding even calling into
dentry_needs_remove_privs() the next time this function is called.
After that commit inode_has_no_xattr() would only be called if
__remove_privs() had to be called.
Restore the old behavior. This is likely the cause of the performance
regression"

LRO/GRO_HW should be disabled if there is an attached XDP program.
BNXT_FLAG_TPA is the current setting of the LRO/GRO_HW. Using
BNXT_FLAG_TPA to disable LRO/GRO_HW will cause these features to be
permanently disabled once they are disabled.

There are 2 issues:
1. We should decrement hw_resc->max_nqs instead of hw_resc->max_irqs
with the number of NQs assigned to the VFs. The IRQs are fixed
on each function and cannot be re-assigned. Only the NQs are being
assigned to the VFs.
2. vf_msix is the total number of NQs to be assigned to the VFs. So
we should decrement vf_msix from hw_resc->max_nqs.

Using BNXT_PAGE_MODE_BUF_SIZE + offset as buffer length value is not
sufficient when running single buffer XDP programs doing redirect
operations. The stack will complain on missing skb tail room. Fix it
by using PAGE_SIZE when calling xdp_init_buff() for single buffer
programs.

Address learning should initially be turned off by the driver for port
operation in standalone mode, then the DSA core handles changes to it
via ds->ops->port_bridge_flags().
Leaving address learning enabled while ports are standalone breaks any
kind of communication which involves port B receiving what port A has
sent. Notably it breaks the ksz9477 driver used with a (non offloaded,
ports act as if standalone) bonding interface in active-backup mode,
when the ports are connected together through external switches, for
redundancy purposes.
This fixes a major design flaw in the ksz9477 and ksz8795 drivers, which
unconditionally leave address learning enabled even while ports operate
as standalone.

An AXI master address translation table property was inadvertently
added to the device tree & this was not caught by dtbs_check at the
time. Remove the property - it should not be in mpfs.dtsi anyway as
it would be more suitable in -fabric.dtsi nor does it actually apply
to the version of the reference design we are using for upstream.

Recent versions of dt-schema warn about a previously undetected
undocumented property:

From schema: Documentation/devicetree/bindings/mmc/cdns,sdhci.yaml
There are no GPIOs connected to MSSIO6B4 pin K3 so adding the common
cd-debounce-delay-ms property makes no sense. The Cadence IP has a
register that sets the card detect delay as "DP * tclk". On MPFS, this
clock frequency is not configurable (it must be 200 MHz) & the FPGA
comes out of reset with this register already set.

Pull parisc fixes from Helge Deller:
"Some interesting background to the current patchset:
It turned out that the fldw instruction (which loads a 32-bit word
from memory into one half of a FP register) failed on unaligned
addresses and even trashed some other random FP register instead. It's
a trivial one-liner fix in the exception handler but this failure
dates back to the very beginnings of the parisc-port. It's strange
that it was never noticed before.
Another patch fixes an annoyance noticed by Randy Dunlap. Running
"make ARCH=parisc64 randconfig" always returned a 32-bit config,
although one would expect a 64-bit config. Masahiro Yamada suggested
to mimik sparc Kconfig code, which fixed the issue nicely. This
allowed to drop some compiler build checks too.
Third, it's possible to build an optimized 32-bit kernel for PA8X00
(64-bit) CPUs, which then wouldn't start on 32-bit-only (PA1.x)
machines. I've added a bootup check which prevents that and which
prints a message to the console. This can be tested with qemu, which
currently only supports 32-bit emulation.
The other patches are usual clean-up stuff like added return value
checks and typo fixes in comments.
Summary:
- Fix emulation of fldw instruction on unaligned addresses
- Fix "make ARCH=parisc64 randconfig" to return a 64-bit config
- Prevent boot if trying to boot a 32-bit kernel compiled for PA8X00
