This is a straight conversion from the old asm/unistd32.h into the
format used by 32-bit arm and most other architectures, calling scripts
to generate the asm/unistd32.h header and a new asm/syscalls32.h headers.
I used a semi-automated text replacement method to do the conversion,
and then used 'vimdiff' to synchronize the whitespace and the (unused)
names of the non-compat syscalls with the arm version.
There are two differences between the generated syscalls names and the
old version:
- the old asm/unistd32.h contained only a __NR_sync_file_range2
entry, while the arm32 version also defines
__NR_arm_sync_file_range with the same number. I added this
duplicate back in asm/unistd32.h.
- __NR__sysctl was removed from the arm64 file a while ago, but
all the tables still contain it. This should probably get removed
everywhere but I added it here for consistency.
On top of that, the arm64 version does not contain any references to
the 32-bit OABI syscalls that are not supported by arm64. If we ever
want to share the file between arm32 and arm64, it would not be
hard to add support for both in one file.

The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be
generated from scripts/syscall.tbl, which makes this consistent with
the other architectures that have their own syscall.tbl.
arc has a couple of architecture specific system calls, which I add to the
generic table. This for some reason includes the deprecated sys_sysfs()
syscall that was presumably added by accident.
The time32, renameat, stat64 and rlimit entries in the syscall_abis_32
entry are for system calls that were part of the generic ABI when arch/arc
got added but are no longer enabled by default for new architectures.
Both the user visible side of asm/unistd.h and the internal syscall
table in the kernel should have the same effective contents after this.

When clone3() was introduced, it was not obvious how each architecture
deals with setting up the stack and keeping the register contents in
a fork()-like system call, so this was left for the architecture
maintainers to implement, with __ARCH_WANT_SYS_CLONE3 defined by those
that already implement it.
Five years later, we still have a few architectures left that are missing
clone3(), and the macro keeps getting in the way as it's fundamentally
different from all the other __ARCH_WANT_SYS_* macros that are meant
to provide backwards-compatibility with applications using older
syscalls that are no longer provided by default.
Address this by reversing the polarity of the macro, adding an
__ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't
already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3
from all the other ones.

There are 11 copies of arch/*/kernel/syscalls/Makefile that all implement
the same basic logic in a somewhat awkward way.
I tried out various ways of unifying the existing copies and ended up
with something that hooks into the logic for generating the redirections
to asm-generic headers. This gives a nicer syntax of being able to list
the generated files in $(syscall-y) inside of arch/*/include/asm/Kbuild
instead of both $(generated-y) in that place and also in another
Makefile.
The configuration for which syscall.tbl file to use and which ABIs to
enable is now done in arch/*/kernel/Makefile.syscalls. I have done
patches for all architectures and made sure that the new generic
rules implement a superset of all the architecture specific corner
cases.
ince the header file is not specific to asm-generic/*.h redirects
now, I ended up renaming the file to scripts/Makefile.asm-headers.

In order to integrate the system call header generation with generating
the asm-generic wrappers, restrict the generated headers to those that
actually exist in include/asm-generic/.
The path is already known, so add these as a dependency.
The asm-generic/bugs.h header was removed in commit 61235b24b9cb ("init:
Remove check_bugs() leftovers"), which now causes a build failure, so
drop it from the list.

The list of generated headers is rather outdated, some of these no longer
exist, while others are already listed in include/asm-generic/Kbuild
so there is no need to list them here.
As we start validating the list of headers against the files that exist,
the outdated ones now cause a warning.

If we start validating the existence of the asm-generic side of
generated headers, this one causes a warning:
make[3]: *** No rule to make target 'arch/um/include/generated/asm/bpf_perf_event.h', needed by 'all'. Stop.
The problem is that the asm-generic header only exists for the uapi
variant, but arch/um has no uapi headers and instead uses the x86
userspace API.
Add a custom file with an explicit redirect to avoid this.

The helper calculate_psi_aligned_address() is used to convert an arbitrary
range into a size-aligned one.
The aligned_pages variable is calculated from input start and end, but is
not adjusted when the start pfn is not aligned and the mask is adjusted,
which results in an incorrect number of pages returned.
The number of pages is used by qi_flush_piotlb() to flush caches for the
first-stage translation. With the wrong number of pages, the cache is not
synchronized, leading to inconsistencies in some cases.

Address mask specifies the number of low order bits of the address field
that must be masked for the invalidation operation.
Since address bits masked start from bit 12, the max address mask should
be MAX_AGAW_PFN_WIDTH, as defined in Table 19 ("Invalidate Descriptor
Address Mask Encodings") of the spec.
Limit the max address mask returned from calculate_psi_aligned_address()
to MAX_AGAW_PFN_WIDTH to prevent potential integer overflow in the

The GSBUSCFG0 register bits [31:16] are used to configure the cache type
settings of the descriptor and data write/read transfers (Cacheable,
Bufferable/Posted). When CCI is enabled in the design, DWC3 core GSBUSCFG0
cache bits must be updated to support CCI enabled transfers in USB.
To program GSBUSCFG0 cache bits create a software node property
in AMD-xilinx dwc3 glue driver and pass it to dwc3 core. The core
then reads this property value and configures it in dwc3_core_init()
sequence.

The size of the internal RAM of the DesignWare USB controller changed
between the different Lantiq SoCs. We have the following sizes:
Amazon + Danube: 8 KByte
Amazon SE + arx100: 2 KByte
xrx200 + xrx300: 2.5 KByte
For Danube SoC we do not provide the params and let the driver decide
to use sane defaults, for the Amazon SE and arx100 we use small fifos
and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
The auto detection of max_transfer_size and max_packet_count should

Since the beginning of time, struct usb_ep::maxpacket was a bitfield,
and when new 16-bit members were added, the convention was followed:
1da177e4c3f41 (Linus Torvalds 2005-04-16 236) unsigned maxpacket:16;
e117e742d3106 (Robert Baldyga 2013-12-13 237) unsigned maxpacket_limit:16;
a59d6b91cbca5 (Tatyana Brokhman 2011-06-28 238) unsigned max_streams:16;
However, there is no need for this as a simple u16 can be used instead,
simplifying the struct and the resulting compiler binary output. Switch
to u16 for all three, and rearrange struct slightly to minimize holes.
No change in the final size of the struct results; the 2 byte gap is
just moved to the end, as seen with pahole:
- /* XXX 2 bytes hole, try to pack */
...
/* size: 72, cachelines: 2, members: 15 */
...
+ /* padding: 2 */
Changing this simplifies future introspection[1] of maxpacket's type during
allocations:
drivers/usb/gadget/function/f_tcm.c:330:24: error: 'typeof' applied to a bit-field
330 | fu->cmd.buf = kmalloc(fu->ep_out->maxpacket, GFP_KERNEL);

Adding stripes to an existing raid4/5/6/10 mapped device grows its
capacity though it'll be only made available _after_ the respective
reshape finished as of MD kernel reshape semantics. Such reshaping
involves moving a window forward starting at BOD reading content
from previous lesser stripes and writing them back in the new
layout with more stripes. Once that process finishes at end of
previous data, the grown size may be announced and used. In order
to avoid writing over any existing data in place, out-of-place space
is added to the beginning of each data device by lvm2 before starting
the reshape process. That reshape space wasn't taken into acount for
data device size calculation.
Fixes resulting from above:
- correct event handling conditions in do_table_event() to set
the device's capacity after the stripe adding reshape ended
- subtract mentioned out-of-place space doing data device and
array size calculations
- conditionally set capacity as of superblock in preresume
Testing:
- passes all LVM2 RAID tests including new lvconvert-raid-reshape-size.sh one

When mutipath_message is called with an action and a device, it needs to
find the pgpath that matches that device. dm_get_device() is not the
right function for this. dm_get_device() will look for a table_device
matching the requested path in use by either the live or inactive table.
If it doesn't find the device, dm_get_device() will open it and add it
to the table. Means that multipath_message will accept any block device,
add it to the table if not present, and then look through the pgpaths
to see if it finds a match. Afterwards it will remove the device if it
was not previously in the table devices list.
This is the only function that can modify the device list of a table
besides the constructors and destructors, and it can only do this when
it was passed an invalid message. Instead, multipath_message() should
call dm_devt_from_path() to get the device dev_t, and match that against
its pgpaths.

There was a performance regression reported where dm-crypt would perform
worse on new kernels than on old kernels. The reason is that the old
kernels split the bios to NVMe request size (that is usually 65536 or
131072 bytes) and the new kernels pass the big bios through dm-crypt and
split them underneath.
If a big 1MiB bio is passed to dm-crypt, dm-crypt processes it on a single
core without parallelization and this is what causes the performance
degradation.
This commit introduces new tunable variables
/sys/module/dm_crypt/parameters/max_read_size and
/sys/module/dm_crypt/parameters/max_write_size that specify the maximum
bio size for dm-crypt. Bios larger than this value are split, so that
they can be encrypted in parallel by multiple cores. If these variables
are '0', a default 131072 is used.
Splitting bios may cause performance regressions in other workloads - if
this happens, the user should increase the value in max_read_size and
max_write_size variables.
max_read_size:
128k 2399MiB/s
256k 2368MiB/s
512k 1986MiB/s
1024 1790MiB/s
max_write_size:
128k 1712MiB/s
256k 1651MiB/s
512k 1537MiB/s
1024k 1332MiB/s
Note that if you run dm-crypt inside a virtual machine, you may need to do
"echo numa >/sys/module/workqueue/parameters/default_affinity_scope" to
improve performance.

net: phy: aquantia: enable support for aqr115c
This series addesses two issues with the aqr115c PHY on Qualcomm
sa8775p-ride-r3 board and adds support for this PHY to the aquantia driver.
While the manufacturer calls the 2.5G PHY mode OCSGMII, we reuse the existing
2500BASEX mode in the kernel to avoid extending the uAPI.
It took me a while to resend because I noticed an issue with the PHY coming
out of suspend with no possible interfaces listed and tracked it to the
GLOBAL_CFG registers for different modes returning 0. A workaround has been
added to the series. Unfortunately the HPG doesn't mention a proper way of
doing it or even mention any such issue at all.
Changes since v2:
- add a patch that addresses an issue with GLOBAL_CFG registers returning 0
- reuse aqr113c_config_init() for aqr115c
- improve commit messages, give more details on the 2500BASEX mode reuse
Link to v2: https://lore.kernel.org/lkml/Zn4Nq1QvhjAUaogb@makrotopia.org/T/
Changes since v1:
- split out the PHY patches into their own series
- don't introduce new mode (OCSGMII) but use existing 2500BASEX instead
- split the wait-for-FW patch into two: one renaming and exporting the
relevant function and the second using it before checking the FW ID

The way the delayed work is handled in ceph_monc_stop() is prone to
races with mon_fault() and possibly also finish_hunting(). Both of
these can requeue the delayed work which wouldn't be canceled by any of
the following code in case that happens after cancel_delayed_work_sync()
runs -- __close_session() doesn't mess with the delayed work in order
to avoid interfering with the hunting interval logic. This part was
missed in commit b5d91704f53e ("libceph: behave in mon_fault() if
cur_mon < 0") and use-after-free can still ensue on monc and objects
that hang off of it, with monc->auth and monc->monmap being
particularly susceptible to quickly being reused.
To fix this:
- clear monc->cur_mon and monc->hunting as part of closing the session
in ceph_monc_stop()
- bail from delayed_work() if monc->cur_mon is cleared, similar to how
it's done in mon_fault() and finish_hunting() (based on monc->hunting)
- call cancel_delayed_work_sync() after the session is closed

The FIXME is very old and probably needed because of some driver bug
like insufficient initialization. It may well be that it was fixed
meanwhile but we never know because the spurious irq is silently
ignored. Add now a call trace when this happens so we have more
information in case the issue still exists.

Add qxl_bo_pin_and_vmap() that pins and vmaps a buffer object in one
step. Update callers of the regular qxl_bo_vmap(). Fixes a bug where
qxl accesses an unpinned buffer object while it is being moved; such
as with the monitor-description BO. An typical error is shown below.

Commit b33651a5c98d ("drm/qxl: Do not pin buffer objects for vmap")
removed the implicit pin operation from qxl's vmap code. This is the
correct behavior for GEM and PRIME interfaces, but the pin is still
needed for qxl internal operation.
Also add a corresponding function qxl_bo_vunmap_and_unpin() and remove
the old qxl_bo_vmap() helpers.
Future directions: BOs should not be pinned or vmapped unnecessarily.
The pin-and-vmap operation should be removed from the driver and a
temporary mapping should be established with a vmap_local-like helper.
See the client helper drm_client_buffer_vmap_local() for semantics.
v2:
- unreserve BO on errors in qxl_bo_pin_and_vmap() (Dmitry)

Setting up HostNotify can be tricky. Support debugging by stating
when a HostNotify alert was received independent of the irq being
mapped. Especially useful with the in-kernel i2c testunit. Update
documentation as well.
