soc: mediatek: SVS: Use DEFINE_SIMPLE_DEV_PM_OPS for svs_pm_ops
When building this driver for an architecture that does not support
CONFIG_PM_SLEEP, such as hexagon, the following warnings occur:
drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function]
static int svs_suspend(struct device *dev)
^
drivers/soc/mediatek/mtk-svs.c:1515:12: error: unused function 'svs_resume' [-Werror,-Wunused-function]
static int svs_resume(struct device *dev)
^
2 errors generated.
This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS,
which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the
functions unused in the eyes of the compiler.
This problem was rectified in commit
1a3c7bb08826 ("PM: core: Add new
*_PM_OPS macros, deprecate old ones") with new macros. Use
DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing
svs_pm_ops when CONFIG_PM_SLEEP is set.

the enum mtk_ddp_comp_id was modified to add an index number to the

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit
0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

Pull ptrace_stop cleanups from Eric Biederman:
"While looking at the ptrace problems with PREEMPT_RT and the problems
Peter Zijlstra was encountering with ptrace in his freezer rewrite I
identified some cleanups to ptrace_stop that make sense on their own
and move make resolving the other problems much simpler.
The biggest issue is the habit of the ptrace code to change
task->__state from the tracer to suppress TASK_WAKEKILL from waking up
the tracee. No other code in the kernel does that and it is straight
forward to update signal_wake_up and friends to make that unnecessary.
Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and
then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying
on the fact that all stopped states except the special stop states can
tolerate spurious wake up and recover their state.
The state of stopped and traced tasked is changed to be stored in
task->jobctl as well as in task->__state. This makes it possible for
the freezer to recover tasks in these special states, as well as
serving as a general cleanup. With a little more work in that
direction I believe TASK_STOPPED can learn to tolerate spurious wake
ups and become an ordinary stop state.
The TASK_TRACED state has to remain a special state as the registers
for a process are only reliably available when the process is stopped
in the scheduler. Fundamentally ptrace needs acess to the saved
register values of a task.
There are bunch of semi-random ptrace related cleanups that were found
while looking at these issues.
One cleanup that deserves to be called out is from commit
57b6de08b5f6
("ptrace: Admit ptrace_stop can generate spuriuos SIGTRAPs"). This
makes a change that is technically user space visible, in the handling
of what happens to a tracee when a tracer dies unexpectedly. According
to our testing and our understanding of userspace nothing cares that
spurious SIGTRAPs can be generated in that case"

firmware_loader: enable XZ by default if compressed support is enabled
Commit
23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed
firmware files") added support for ZSTD compression, but in the process
also made the previously default XZ compression a config option.
That means that anybody who upgrades their kernel and does a
make oldconfig
to update their configuration, will end up without the XZ compression
that the configuration used to have.
Add the 'default y' to make sure this doesn't happen.
The whole compression question should probably be improved upon, since
it is now possible to "enable" compression in the kernel config but not
enable any actual compression algorithm, which makes it all very
useless. It makes no sense to ask Kconfig questions that enable
situations that are nonsensical like that.
This at least fixes the immediate problem of a kernel update resulting
in a nonbootable machine because of a missed option.

"This is the majority of the loongarch architecture code, including the
final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so it
is currently impossible to boot the kernel, until the loongarch
specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the PCI
subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI for
the libc ports to build on, and to help any treewide changes in the
mainline kernel get applied here as well.

perf mem: Trace physical address for Arm SPE events
Currently, Arm SPE events don't trace physical address, therefore, the
field 'phys_addr' is always zero in synthesized memory samples. This
leads to perf c2c tool cannot locate the memory node for samples.
This patch enables configuration 'pa_enable' for Arm SPE events, so the
physical address packet can be traced, finally this can allow perf c2c
tool to locate properly for memory node.

perf record: Support sample-read topdown metric group for hybrid platforms
With the hardware TopDown metrics feature, the sample-read feature should
be supported for a TopDown group, e.g., sample a non-topdown event and read
a Topdown metric group. But the current perf record code errors are out.
For a TopDown metric group,the slots event must be the leader of the group,
but the leader slots event doesn't support sampling. To support sample-read
the TopDown metric group, uses the 2nd event of the group as the "leader"
for the purposes of sampling.
Only the platform with the TopDown metric feature supports sample-read the
topdown group. In commit
acb65150a47c ("perf record: Support sample-read
topdown metric group"), it adds arch_topdown_sample_read() to indicate
whether the TopDown group supports sample-read, it should only work on the
non-hybrid systems, this patch extends the support for hybrid platforms.
Before:
# ./perf record -e "{cpu_core/slots/,cpu_core/cycles/,cpu_core/topdown-retiring/}:S" -a sleep 1
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/topdown-retiring/).
/bin/dmesg | grep -i perf may provide additional information.

perf unwind: Fix segbase for ld.lld linked objects
segbase is the address of .eh_frame_hdr and table_data is segbase plus
the header size. find_proc_info computes segbase as `map->start +
segbase - map->pgoff` which is wrong when
* .eh_frame_hdr and .text are in different PT_LOAD program headers
* and their p_vaddr difference does not equal their p_offset difference
Since 10.0, ld.lld's default --rosegment -z noseparate-code layout has
such R and RX PT_LOAD program headers.
ld.lld (default) => perf report fails to unwind `perf record
--call-graph dwarf` recorded data
ld.lld --no-rosegment => ok (trivial, no R PT_LOAD)
ld.lld -z separate-code => ok but by luck: there are two PT_LOAD but
their p_vaddr difference equals p_offset difference
ld.bfd -z noseparate-code => ok (trivial, no R PT_LOAD)
ld.bfd -z separate-code (default for Linux/x86) => ok but by luck:
there are two PT_LOAD but their p_vaddr difference equals p_offset
difference
To fix the issue, compute segbase as dso's base address plus
PT_GNU_EH_FRAME's p_vaddr. The base address is computed by iterating
over all dso-associated maps and then subtract the first PT_LOAD p_vaddr
(the minimum guaranteed by generic ABI) from the minimum address.
In libunwind, find_proc_info transitively called by unw_step is cached,
so the iteration overhead is acceptable.

perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systems
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need
extend API arch_evsel__must_be_in_group() to support hybrid systems.
In the origin code, for hybrid system event "cpu_core/slots/", the output
of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be
"true"). Currently only one API evsel__remove_from_group() calls it. In
evsel__remove_from_group(), it adds the second condition to check, so the
output of evsel__remove_from_group() still is correct. That's the reason
why there isn't an instant error. I'd like to fix the issue found in API
arch_evsel__must_be_in_group() in case someone else using the function in
the other place.

driver core: Set default deferred_probe_timeout back to 0.
Since we had to effectively reverted
commit
35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits
until the deferred_probe_timeout fires") in an earlier patch, a non-zero
deferred_probe_timeout will break NFS rootfs mounting [1] again. So, set
the default back to zero until we can fix that.
