Microcode gets reloaded late only if "1" is written to the reload file.
However, the code silently treats any other unsigned integer as a

Make the loader more strict to accept only "1" as a trigger value and

When SVE was initially merged we chose to export the maximum VQ in the ABI
as being 512, rather more than the architecturally supported maximum of 16.
For the ptrace tests this results in us generating a lot of test cases and
hence log output which are redundant since a system couldn't possibly
support them. Instead only check values up to the current architectural
limit, plus one more so that we're covering the constraining of higher
vector lengths.
This makes no practical difference to our test coverage, speeds things up
on slower consoles and makes the output much more managable.

commit bd500361a9 ("ACPI: PPTT: Update acpi_find_last_cache_level()

updates the prototype of acpi_get_cache_info(). The cache 'levels'
is update through a pointer and not the return value of the function.
If CONFIG_ACPI_PPTT is not defined, acpi_get_cache_info() doesn't
update its *levels and *split_levels parameters and returns 0.
This can lead to a faulty behaviour.
Make acpi_get_cache_info() return an error code if CONFIG_ACPI_PPTT

Also,

When validating drafted SPDK ublk target, in a case that
assigning large queue depth to multiqueue ublk device,
ublk target would run into a weird incorrect state. During
rounds of review and debug, An overflow bug was found
in ublk driver.
In ublk_cmd.h, UBLK_MAX_QUEUE_DEPTH is 4096 which means
each ublk queue depth can be set as large as 4096. But
when setting qd for a ublk device,
sizeof(struct ublk_queue) + depth * sizeof(struct ublk_io)
will be larger than 65535 if qd is larger than 2728.
Then queue_size is overflowed, and ublk_get_queue()
references a wrong pointer position. The wrong content of
ublk_queue elements will lead to out-of-bounds memory
access.
Extend queue_size in ublk_device as "unsigned int".

In order to re-write Jcc.d32 instructions text_poke_bp() needs to be
taught about them.
The biggest hurdle is that the whole machinery is currently made for 5
byte instructions and extending this would grow struct text_poke_loc
which is currently a nice 16 bytes and used in an array.
However, since text_poke_loc contains a full copy of the (s32)
displacement, it is possible to map the Jcc.d32 2 byte opcodes to
Jcc.d8 1 byte opcode for the int3 emulation.
This then leaves the replacement bytes; fudge that by only storing the

be prefixed with a 0x0f byte.

The PSCI suspend code is currently instrumentable, which is not safe as
instrumentation (e.g. ftrace) may try to make use of RCU during idle
periods when RCU is not watching.
To fix this we need to ensure that psci_suspend_finisher() and anything
it calls are not instrumented. We can do this fairly simply by marking
psci_suspend_finisher() and the psci*_cpu_suspend() functions as
noinstr, and the underlying helper functions as __always_inline.
When CONFIG_DEBUG_VIRTUAL=y, __pa_symbol() can expand to an out-of-line
instrumented function, so we must use __pa_symbol_nodebug() within
psci_suspend_finisher().
The raw SMCCC invocation functions are written in assembly, and are not

memblock_merge_regions() is called after regions have been modified to
merge the neighboring compatible regions. That will check all regions
but most checks are useless.
Most of the time we only insert one or a few new regions, or modify one or
a few regions. At this time, we don't need to check all the regions. We
only need to check the changed regions, because other not related regions
cannot be merged.
Add two parameters to memblock_merge_regions() to indicate the lower and
upper boundary to scan.
Debug code that counts the number of total iterations in
memblock_merge_regions(), like for instance
void memblock_merge_regions(struct memblock_type *type)
{
static int iteration_count = 0;
static int max_nr_regions = 0;
max_nr_regions = max(max_nr_regions, (int)type->cnt);
...
while () {
iteration_count++;
...
}
pr_info("iteration_count: %d max_nr_regions %d", iteration_count,
max_nr_regions);
}
Produces the following numbers on a physical machine with 1T of memory:
before: [2.472243] iteration_count: 45410 max_nr_regions 178
after: [2.470869] iteration_count: 923 max_nr_regions 176
The actual startup speed seems to change little, but it does reduce the
scan overhead.

If a compatible misses a match data entry, then something is wrong in
the development phase, we don't need to check for that at runtime.

We only ever call the SoC specific probe function from
svs_platform_probe. No need to carry that function in a global
datastructure around.

Some projects might not support CONFIG_DEBUG_FS but still needs svs to be
alive. Therefore, enclose debug cmd codes with CONFIG_DEBUG_FS to make sure
svs can be alive when CONFIG_DEBUG_FS not supported.
