These patches are based on Martin Petersen's 6.11/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git 6.11/scsi-queue
The functional changes of note to smartpqi are for: multipath failover
and improving the accuracy of our RAID bypass counter.
For multipath we are:
Reverting commit 94a68c814328 ("scsi: smartpqi: Quickly propagate
path failures to SCSI midlayer") because under certain rare
conditions involving encryption-enabled devices, a false path
failure is reported to the SML causing multipath to failover to
the other path.
Improving errors returned from the driver back to the SML by
checking for error codes returned from the firmware and returning
the correct ASC/ASCQ codes to the SML.
The other two patches add PCI-IDs for new controllers and change the
driver version.

Improve multipath failovers by mapping firmware errors into I/O errors.
In some rare instances, firmware does not return the proper error code for
I/O errors caused by a multipath path failure.
Map I/O errors returned by firmware into errors that help the multipath
layer to detect the failure of a path.

Correct a rare multipath failure issue by reverting commit 94a68c814328
("scsi: smartpqi: Quickly propagate path failures to SCSI midlayer") [1].
Reason for revert: The patch propagated the path failure to SML quickly
when one of the path fails during IO and AIO path gets disabled for a
multipath device.
But it created a new issue: when creating a volume on an encryption-enabled
controller, the firmware reports the AIO path is disabled, which cause the
driver to report a path failure to SML for a multipath device.
There will be a new fix to handle "Illegal request" and "Invalid field in
parameter list" on RAID path when the AIO path is disabled on a multipath
device.

The original implementation of this counter used an atomic variable.
However, this implementation negatively impacted performance in some

A kref imbalance occurs when handling an unsolicited PRLO in direct
attached topology.
Rework PRLO rcv handling when in MAPPED state. Save the state that we were
handling a PRLO by setting nlp_last_elscmd to ELS_CMD_PRLO. Then in the
lpfc_cmpl_els_logo_acc() completion routine, manually restart discovery.
By issuing the PLOGI, which nlp_gets, before nlp_put at the end of the
lpfc_cmpl_els_logo_acc() routine, we are saving us from a final nlp_put.
And, we are still allowing the unreg_rpi to happen.

topology
In direct attached topology, certain target vendors that are quick to issue
FLOGI followed by a cable pull for more than dev_loss_tmo may result in a
kref imbalance for the remote port ndlp object.
Add an nlp_get when the defer_flogi_acc flag is set. This is expected to
balance the nlp_put in the defer_flogi_acc clause in the
lpfc_issue_els_flogi() routine. Because we need to retain the ndlp ptr,
reorganize all of the defer_flogi_acc information into one
lpfc_defer_flogi_acc struct.

The vport->vmid_flag is unintentionally cleared twice after an issue_lip
via the lpfc_reinit_vmid routine().
The first call to lpfc_reinit_vmid() is in lpfc_cmpl_els_flogi(). Then
lpfc_cmpl_els_flogi_fabric() calls lpfc_register_new_vport(), which calls
lpfc_cmpl_reg_new_vport() when the mbox command completes and calls
lpfc_reinit_vmid() a second time.
Fix by moving the vmid_flag clear outside of the lpfc_reinit_vmid() routine
so that vmid_flag is only cleared once upon FLOGI completion.

The default UIC command timeout still remains 500ms. Allow platform
drivers to override the UIC command timeout if desired.
In a real product, the 500ms timeout value is probably good enough.
However, during the product development where there are a lot of logging
and debug messages being printed to the UART console, interrupt starvations
happen occasionally because the UART may print long debug messages from
different modules in the system. While printing, the UART may have
interrupts disabled for more than 500ms, causing UIC command timeout. The
UIC command timeout would trigger more printing from the UFS driver, and
eventually a watchdog timeout may occur unnecessarily.
Add support for overriding the UIC command timeout value with the newly
created uic_cmd_timeout kernel module parameter. Default value is
500ms. Supported values range from 500ms to 2 seconds.

This replaces some of the last remaining uses in the kernel of
1-element "fake" flexible arrays with modern C99 flexible arrays. Some

flexible arrays
Replace the deprecated[1] use of 1-element arrays in struct sgmap, struct
sgmap64, struct sgmapraw, struct user_sgmap, and struct user_sgmap64 with
modern flexible arrays. Additionally remove struct user_sgmapraw as it is
unused.
The resulting binary output differences from this change are limited only
to stack space consumption of the smaller "srbu" variable in
aac_issue_safw_bmic_identify() and aac_get_safw_ciss_luns(), as well as the
smaller associated pair of memcpy()s in
aac_send_safw_bmic_cmd(). Artificially growing the size of srbu back to its
prior size removes all binary differences[2].
As an aside, after studying the aacraid driver code I wonder how
aac_send_wellness_command() ever works. It is reporting a size 4 bytes too
small for what it has constructed in memory in the DMA region: sgentry64 is
size 12, whereas sgentry is size 8. Perhaps the hardware doesn't
care. (Regardless, it is unchanged by this patch.)

struct aac_srb_unit contains struct aac_srb, which contains struct sgmap,
which ends in a (currently) "fake" (1-element) flexible array. Converting
this to a flexible array is needed so that runtime bounds checking won't
think the array is fixed size (i.e. under CONFIG_FORTIFY_SOURCE=y and/or
CONFIG_UBSAN_BOUNDS=y), as other parts of aacraid use struct sgmap as a
flexible array.
It is not legal to have a flexible array in the middle of a structure, so
it either needs to be split up or rearranged so that it is at the end of
the structure. Luckily, struct aac_srb_unit, which is exclusively
consumed/updated by aac_send_safw_bmic_cmd(), does not depend on member
ordering.
The values set in the on-stack struct aac_srb_unit instance "srbu" by the
only two callers, aac_issue_safw_bmic_identify() and
aac_get_safw_ciss_luns(), do not contain anything in srbu.srb.sgmap.sg, and
they both implicitly initialize srbu.srb.sgmap.count to 0 during
memset(). For example:
memset(&srbu, 0, sizeof(struct aac_srb_unit));
srbcmd = &srbu.srb;
srbcmd->flags = cpu_to_le32(SRB_DataIn);
srbcmd->cdb[0] = CISS_REPORT_PHYSICAL_LUNS;
srbcmd->cdb[1] = 2; /* extended reporting */
srbcmd->cdb[8] = (u8)(datasize >> 8);
srbcmd->cdb[9] = (u8)(datasize);
rcode = aac_send_safw_bmic_cmd(dev, &srbu, phys_luns, datasize);
During aac_send_safw_bmic_cmd(), a separate srb is mapped into DMA, and has
srbu.srb copied into it:
srb = fib_data(fibptr);
memcpy(srb, &srbu->srb, sizeof(struct aac_srb));
Only then is srb.sgmap.count written and srb->sg populated:
srb->count = cpu_to_le32(xfer_len);
sg64 = (struct sgmap64 *)&srb->sg;
sg64->count = cpu_to_le32(1);
sg64->sg[0].addr[1] = cpu_to_le32(upper_32_bits(addr));
sg64->sg[0].addr[0] = cpu_to_le32(lower_32_bits(addr));
sg64->sg[0].count = cpu_to_le32(xfer_len);
But this is happening in the DMA memory, not in srbu.srb. An attempt to
copy the changes back to srbu does happen:
/*
* Copy the updated data for other dumping or other usage if
* needed
*/
memcpy(&srbu->srb, srb, sizeof(struct aac_srb));
But this was never correct: the sg64 (3 u32s) overlap of srb.sg (2 u32s)
always meant that srbu.srb would have held truncated information and any
attempt to walk srbu.srb.sg.sg based on the value of srbu.srb.sg.count
would result in attempting to parse past the end of srbu.srb.sg.sg[0] into
srbu.srb_reply.
After getting a reply from hardware, the reply is copied into
srbu.srb_reply:
srb_reply = (struct aac_srb_reply *)fib_data(fibptr);
memcpy(&srbu->srb_reply, srb_reply, sizeof(struct aac_srb_reply));
This has always been fixed-size, so there's no issue here. It is worth
noting that the two callers _never check_ srbu contents -- neither
srbu.srb nor srbu.srb_reply is examined. (They depend on the mapped
xfer_buf instead.)
Therefore, the ordering of members in struct aac_srb_unit does not matter,
and the flexible array member can moved to the end.
(Additionally, the two memcpy()s that update srbu could be entirely
removed as they are never consumed, but I left that as-is.)

flexible array
Replace the deprecated[1] use of a 1-element array in struct
MR_HOST_DEVICE_LIST with a modern flexible array.
One binary difference appears in megasas_host_device_list_query():
struct MR_HOST_DEVICE_LIST *ci;
...
ci = instance->host_device_list_buf;
...
memset(ci, 0, sizeof(*ci));
The memset() clears only the non-flexible array fields. Looking at the rest
of the function, this appears to be fine: firmware is using this region to
communicate with the kernel, so it likely never made sense to clear the
first MR_HOST_DEVICE_LIST_ENTRY.

This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.
That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.
The complexity of those macros stems from two issues:
(a) trying to use them in situations that require a C constant
expression (in static initializers and for array sizes)
(b) the type sanity checking
and MIN_T/MAX_T avoids both of these issues.
Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.
But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.
However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.
This does exactly that.
Which in turn will then allow for much simpler implementations of
min_t()/max_t(). All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.
We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:
$ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.
All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define
Misc:
- A warning has been added to inform users of an unsupported
configuration when mixing CXL VH and RCH/RCD hierarchies
- The ENXIO error code has been replaced with EBUSY for inject poison
