Switch HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE to be a version number
test on libtraceevent being >= to version 1.5.0. This also corrects a
greater-than test to be greater-than-or-equal.

The LLVM template is first echo-ed into command_out and then
command_out executed. The echo surrounds the template with double
quotes, however, the template itself may contain quotes. This is
generally innocuous but in tools/perf/tests/bpf-script-test-prologue.c
we see:
...
SEC("func=null_lseek file->f_mode offset orig")
...
where the first double quote ends the double quote of the echo, then
the > redirects output into a file called f_mode.
To avoid this inadvertent behavior substitute redirects and similar
characters to be ASCII control codes, then substitute the output in
the echo back again.
Fixes: 5eab5a7ee032acaa ("perf llvm: Display eBPF compiling command in debug output")

Add general topdown L1 metrics for neoverse-n2-v2. Due to the wrong
count of stall_slot and stall_slot_frontend on neoverse-n2, the real
stall_slot and real stall_slot_frontend need to subtract cpu_cycles,
so overwrite the "MetricExpr" for neoverse-n2 which slots are 5.
Reference from ARM neoverse-n2 errata notice [0], D117.
Since neoverse-n2/neoverse-v2 does not yet support topdown L2, metric
groups such as Cache, TLB, Branch, InstructionsMix and PEutilization
will be added to further analysis of performance bottlenecks in the
following patches. Reference from ARM PMU guide [1][2].

The slots in each architecture may be different, so add #slots literal
to obtain the slots of different architectures, and the #slots can be
applied in the metric. Currently, The #slots just support for arm64,
and other architectures will return NAN.
On arm64, the value of slots is from the register PMMIR_EL1.SLOT, which
I can read in /sys/bus/event_source/device/armv8_pmuv3_*/caps/slots.
PMMIR_EL1.SLOT might read as zero if the PMU version is lower than
ID_AA64DFR0_EL1_PMUVer_V3P4 or the STALL_SLOT event is not implemented.

Currently flame graph generation requires a d3-flame-graph template to
be installed. Unfortunately this is hard to come by for things like
Debian [1].
If the template isn't installed then ask if it should be downloaded from
jsdelivr CDN. The downloaded HTML file is validated against an md5sum.
If the download fails, generate a minimal flame graph with the
javascript coming from links to jsdelivr CDN.
v3. Adds a warning message and quits before download in live mode.
v2. Change the warning to a prompt about downloading and add the
--allow-download command line flag. Add an md5sum check for the
downloaded HTML.

"Fix a missing elf_hwcap, fix some stack unwinder bugs and two trivial
cleanups"

betopff_init() only checks the total sum of the report counts for each
report field to be at least 4, but hid_betopff_play() expects 4 report
fields.
A device advertising an output report with one field and 4 report counts
would pass the check but crash the kernel with a NULL pointer dereference
in hid_betopff_play().

Make sure calibration values are defined to prevent potential kernel
crashes. This fixes a hypothetical issue for virtual or clone devices
inspired by a similar fix for DS4.

Some DualShock4 devices report invalid calibration data resulting
in kernel oopses due to division by zero during report handling.
The devices affected generally appear to be clone devices, which don't
implement all reports properly and don't populate proper calibration
data. The issue may have been seen on an official device with erased
calibration reports.
This patch prevents the crashes by essentially disabling calibration
when invalid values are detected.

Add a check for empty report_list in bigben_probe().
The missing check causes a type confusion when issuing a list_entry()
on an empty report_list.
The problem is caused by the assumption that the device must
have valid report_list. While this will be true for all normal HID
devices, a suitably malicious device can violate the assumption.

When exception is triggered, code flow go handle_\exception in some
cases. One of stackframe in this case as follows,
high -> +-------+
| REGS | <- a pt_regs
| |
| | <- ex trigger
| REGS | <- ex pt_regs <-+
| | |
| | |
low -> +-------+ ->unwind-+
When unwinder unwinds to handler_\exception it cannot go on prologue
analysis. Because it is an asynchronous code flow, we should get the
next frame PC from regs->csr_era rather than regs->regs[1]. At init time
we copy the handlers to eentry and also copy them to NUMA-affine memory
named pcpu_handlers if NUMA is enabled. Thus, unwinder cannot unwind
normally. To solve this, we try to give some hints in handler_\exception
and fixup unwinders in unwind_next_frame().

The prolugue unwinder rely on symbol info. When PC is not in kernel text
address, it cannot find relative symbol info and it will be broken. The
guess unwinder will be used in this case. And the guess unwinder code in
prolugue unwinder is redundant. Strip it out and set the unwinder type
in unwind_state. Make guess_unwinder::unwind_next_frame() as default way
when other unwinders cannot unwind in some extreme case.

The stack frame when function_graph enable like follows,
--------- <- function sp_on_entry
|
|
|
FAKE_RA <- sp_on_entry - sizeof(pt_regs) + PT_R1
|
--------- <- sp_on_entry - sizeof(pt_regs)
So if we want to get the &FAKE_RA we should get sp_on_entry first. In
the unwinder_prologue case, we can get the sp_on_entry as state->sp,
because we try to calculate each CFA and the ra saved address. But in
the unwinder_guess case, we cannot get it because we do not try to
calculate the CFA. Although LoongArch have not fixed frame, the $ra is
saved at CFA - 8 in most cases, we can try guess, too. As we store the
pc in state, we not need to dereference state->sp, too.

If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
only releases pages to the buddy allocator if they are not in the
deferred range. This is correct for free pages (as defined by
for_each_free_mem_pfn_range_in_zone()) because free pages in the
deferred range will be initialized and released as part of the deferred
init process. memblock_free_pages() is called by memblock_free_late(),
which is used to free reserved ranges after memblock_free_all() has
run. All pages in reserved ranges have been initialized at that point,
and accordingly, those pages are not touched by the deferred init
process. This means that currently, if the pages that
memblock_free_late() intends to release are in the deferred range, they
will never be released to the buddy allocator. They will forever be
reserved.
In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
which is also correct for free pages but is not correct for reserved
pages. KMSAN metadata for reserved pages is initialized by
kmsan_init_shadow(), which runs shortly before memblock_free_all().
For both of these reasons, memblock_free_pages() should only be called
for free pages, and memblock_free_late() should call __free_pages_core()
directly instead.
One case where this issue can occur in the wild is EFI boot on
x86_64. The x86 EFI code reserves all EFI boot services memory ranges
via memblock_reserve() and frees them later via memblock_free_late()
(efi_reserve_boot_services() and efi_free_boot_services(),
respectively). If any of those ranges happens to fall within the
deferred init range, the pages will not be released and that memory will
be unavailable.
For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:

Pull memblock fix from Mike Rapoport:
"memblock: always release pages to the buddy allocator in
memblock_free_late()
If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
only releases pages to the buddy allocator if they are not in the
deferred range. This is correct for free pages (as defined by
for_each_free_mem_pfn_range_in_zone()) because free pages in the
deferred range will be initialized and released as part of the
deferred init process.
memblock_free_pages() is called by memblock_free_late(), which is used
to free reserved ranges after memblock_free_all() has run. All pages
in reserved ranges have been initialized at that point, and
accordingly, those pages are not touched by the deferred init process.
This means that currently, if the pages that memblock_free_late()
intends to release are in the deferred range, they will never be
released to the buddy allocator. They will forever be reserved.
In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
which is also correct for free pages but is not correct for reserved
pages. KMSAN metadata for reserved pages is initialized by
kmsan_init_shadow(), which runs shortly before memblock_free_all().
For both of these reasons, memblock_free_pages() should only be called
for free pages, and memblock_free_late() should call
__free_pages_core() directly instead.
One case where this issue can occur in the wild is EFI boot on x86_64.
The x86 EFI code reserves all EFI boot services memory ranges via
memblock_reserve() and frees them later via memblock_free_late()
(efi_reserve_boot_services() and efi_free_boot_services(),
respectively).
If any of those ranges happens to fall within the deferred init range,
the pages will not be released and that memory will be unavailable.
For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:
