This patch implements ftrace trampolines through plt entry.
Tested by forcing ftrace_make_call() to use the module PLT, and then
loading up a module after setting up ftrace with:
| echo ":mod:<module-name>" > set_ftrace_filter;
| echo function > current_tracer;
| modprobe <module-name>
Since FTRACE_ADDR/FTRACE_REGS_ADDR is only defined when CONFIG_DYNAMIC_
FTRACE is selected, we wrap their usage in module_init_ftrace_plt() with
ifdeffery rather than using IS_ENABLED().

Once the function_graph tracer is enabled, a filtered function has the
following call sequence:
1) ftracer_caller ==> on/off by ftrace_make_call/ftrace_make_nop
2) ftrace_graph_caller
3) ftrace_graph_call ==> on/off by ftrace_en/disable_ftrace_graph_caller
4) prepare_ftrace_return
Considering the following DYNAMIC_FTRACE_WITH_REGS feature, it would be
more extendable to have a ftrace_graph_caller function, instead of
calling prepare_ftrace_return directly in ftrace_caller.

The compiler has inserted 2 NOPs before the regular function prologue.
T series registers are available and safe because of LoongArch's psABI.
At runtime, we can replace nop with bl to enable ftrace call and replace
bl with nop to disable ftrace call. The bl instruction requires us to
save the original RA value, so it saves RA at t0 here.
Details are:
| Compiled | Disabled | Enabled |
+------------+------------------------+------------------------+
| nop | move t0, ra | move t0, ra |
| nop | nop | bl ftrace_caller |
| func_body | func_body | func_body |
The RA value will be recovered by ftrace_regs_entry, and restored into
RA before returning to the regular function prologue. When a function is
not being traced, the "move t0, ra" is not harmful.
1) ftrace_make_call, ftrace_make_nop (in kernel/ftrace.c)
The two functions turn each recorded call site of filtered functions
into a call to ftrace_caller or nops.
2) ftracce_update_ftrace_func (in kernel/ftrace.c)
turns the nops at ftrace_call into a call to a generic entry for
function tracers.
3) ftrace_caller (in kernel/mcount_dyn.S)
The entry where each _mcount call sites calls to once they are
filtered to be traced.

Recordmcount utility under scripts is run, after compiling each object,
to find out all the locations of calling _mcount() and put them into
specific seciton named __mcount_loc.
Then the linker collects all such information into a table in the kernel
image (between __start_mcount_loc and __stop_mcount_loc) for later use
by ftrace.
This patch adds LoongArch specific definitions to identify such locations.
And on LoongArch, only the C version is used to build the kernel now that
CONFIG_HAVE_C_RECORDMCOUNT is on.

This patch contains basic ftrace support for LoongArch. Specifically,
function tracer (HAVE_FUNCTION_TRACER), function graph tracer (HAVE_
FUNCTION_GRAPH_TRACER) are implemented following the instructions in
Documentation/trace/ftrace-design.txt.
Use `-pg` makes stub like a child function `void _mcount(void *ra)`.
Thus, it can be seen store RA and alloc stack before `call _mcount`.
Find `alloc stack` at first, and then find `store RA`.
Note that the functions in both inst.c and time.c should not be hooked
with the compiler's -pg option: to prevent infinite self-referencing for
the former, and to ignore early setup stuff for the latter.

Instead of saving a pointer to the .got, .plt and .plt_idx sections to
apply {got,plt}-based relocations, save and use their section indices
instead.
The mod->arch.{core,init}.{got,plt} pointers were problematic for live-
patch because they pointed within temporary section headers (provided by
the module loader via info->sechdrs) that would be freed after module
load. Since livepatch modules may need to apply relocations post-module-
load (for example, to patch a module that is loaded later), using section
indices to offset into the section headers (instead of accessing them
through a saved pointer) allows livepatch modules on LoongArch to pass
in their own copy of the section headers to apply_relocate_add() to
apply delayed relocations.
The method used is same as commit c8ebf64eab ("arm64/module: use plt
section indices for relocations").

Inspired by commit 800834285361("bpf, arm64: Add BPF exception tables"),
do similar to LoongArch to add BPF exception tables.
When a tracing BPF program attempts to read memory without using the
bpf_probe_read() helper, the verifier marks the load instruction with
the BPF_PROBE_MEM flag. Since the LoongArch JIT does not currently
recognize this flag it falls back to the interpreter.
Add support for BPF_PROBE_MEM, by appending an exception table to the
BPF program. If the load instruction causes a data abort, the fixup
infrastructure finds the exception table and fixes up the fault, by
clearing the destination register and jumping over the faulting
instruction.
To keep the compact exception table entry format, inspect the pc in
fixup_exception(). A more generic solution would add a "handler" field
to the table entry, like on x86, s390 and arm64, etc.

Inspired by commit 2e77a62cb3a6("arm64: extable: add a dedicated uaccess
handler"), do similar to LoongArch to add a dedicated uaccess exception
handler to update registers in exception context and subsequently return
back into the function which faulted, so we remove the need for fixups
specialized to each faulting instruction.
Add gpr-num.h here because we need to map the same GPR names to integer
constants, so that we can use this to build meta-data for the exception
fixups.
The compiler treats gpr 0 as zero rather than $r0, so set it separately
to .L__gpr_num_zero, otherwise the following assembly error will occurs:
{standard input}: Assembler messages:

This is a LoongArch port of commit d6e2cc5647 ("arm64: extable: add
`type` and `data` fields").
Subsequent patches will add specialized handlers for fixups, in addition
to the simple PC fixup we have today. In preparation, this patch adds a
new `type` field to struct exception_table_entry, and uses this to
distinguish the fixup and other cases. A `data` field is also added so
that subsequent patches can associate data specific to each exception
site (e.g. register numbers).
Handlers are named ex_handler_*() for consistency, following the example
of x86. At the same time, get_ex_fixup() is split out into a helper so
that it can be used by other ex_handler_*() functions in the subsequent
patches.

Similar to other architectures such as arm64, x86, riscv and so on, use
offsets relative to the exception table entry values rather than their
absolute addresses for both the exception location and the fixup.
However, LoongArch label difference because it will actually produce two
relocations, a pair of R_LARCH_ADD32 and R_LARCH_SUB32. Take simple code
below for example:
$ cat test_ex_table.S
.section .text
1:
nop
.section __ex_table,"a"
.balign 4
.long (1b - .)
.previous
$ loongarch64-unknown-linux-gnu-gcc -c test_ex_table.S
$ loongarch64-unknown-linux-gnu-readelf -Wr test_ex_table.o
Relocation section '.rela__ex_table' at offset 0x100 contains 2 entries:
Offset Info Type Symbol's Value Symbol's Name + Addend
0000000000000000 0000000600000032 R_LARCH_ADD32 0000000000000000 .L1^B1 + 0
0000000000000000 0000000500000037 R_LARCH_SUB32 0000000000000000 L0^A + 0
The modpost will complain the R_LARCH_SUB32 relocation, so we need to
patch modpost.c to skip this relocation for .rela__ex_table section.

Pull EFI updates from Ard Biesheuvel:
"Another fairly sizable pull request, by EFI subsystem standards.
Most of the work was done by me, some of it in collaboration with the
distro and bootloader folks (GRUB, systemd-boot), where the main focus
has been on removing pointless per-arch differences in the way EFI
boots a Linux kernel.
- Refactor the zboot code so that it incorporates all the EFI stub
logic, rather than calling the decompressed kernel as a EFI app.
- Add support for initrd= command line option to x86 mixed mode.
- Allow initrd= to be used with arbitrary EFI accessible file systems
instead of just the one the kernel itself was loaded from.
- Move some x86-only handling and manipulation of the EFI memory map
into arch/x86, as it is not used anywhere else.
- More flexible handling of any random seeds provided by the boot
environment (i.e., systemd-boot) so that it becomes available much
earlier during the boot.
- Allow improved arch-agnostic EFI support in loaders, by setting a
uniform baseline of supported features, and adding a generic magic
number to the DOS/PE header. This should allow loaders such as GRUB
or systemd-boot to reduce the amount of arch-specific handling
substantially.
- (arm64) Run EFI runtime services from a dedicated stack, and use it
to recover from synchronous exceptions that might occur in the
firmware code.
- (arm64) Ensure that we don't allocate memory outside of the 48-bit
addressable physical range.
- Make EFI pstore record size configurable
- Add support for decoding CXL specific CPER records"

Pull modules updates from Luis Chamberlain:
"Tux gets for xmas an improvement to the average lookup performance of
kallsyms_lookup_name() by 715x thanks to the work by Zhen Lei, which
upgraded our old implementation from being O(n) to O(log(n)), while
also retaining the old implementation support on /proc/kallsyms.
The only penalty was increasing the memory footprint by 3 *
kallsyms_num_syms. Folks who want to improve this further now also
have a dedicated selftest facility through KALLSYMS_SELFTEST.
Stephen Boyd added zstd in-kernel decompression support, but the only
users of this would be folks using the load-pin LSM because otherwise
we do module decompression in userspace.
The only other thing with mentioning is a minor boot time optimization
by Rasmus Villemoes which deferes param_sysfs_init() to late init. The
rest is cleanups and minor fixes"

Pull clk driver updates from Stephen Boyd:
"A pile of clk driver updates with a small tracepoint patch to the clk
core this time around.
The core framework is effectively unchanged, with the majority of the
diff going to the Qualcomm clk driver directory because they added two
3k line files that are almost all clk data (Abel Vesa from Linaro
tried to shrink the number of lines down, but it doesn't seem to be
possible without sacrificing readability).
The second big driver this time around is the Rockchip rk3588 clk and
reset unit, at _only_ 2.5k lines.
Ignoring the big clk drivers from the familiar SoC vendors, there's
just a bunch of little clk driver updates and fixes throughout here.
It's the usual set of clk data fixups to describe proper parents, or
add frequencies to frequency tables, or plug memory leaks when
function calls fail. Also, some drivers are converted to use modern
clk_hw APIs, which is always nice to see. And data is deduplicated,
leading to a smaller kernel Image.
Overall this batch has a larger collection of cleanups than it
typically does. Maybe that means there are less new SoCs right now
that need supporting, and the focus has shifted to quality and
reliability. I can dream.
New Drivers:
- Frequency hopping controller hardware on MediaTek MT8186
- Global clock controller for Qualcomm SM8550
- Display clock controller for Qualcomm SC8280XP
- RPMh clock controller for Qualcomm QDU1000 and QRU1000 SoCs

Pull pin control updates from Linus Walleij:
"The two large chunks is the header clean-up from Andy and the Qualcomm
DT bindings clean-up from Krzysztof. Each which could give rise to
conflicts, but I haven't seen any.
The YAML conversions happening around the device tree is the biggest
item in the series and is the result of Rob Herrings ambition to
autovalidate these trees against strict schemas and it is paying off
in lots of bugs found and ever prettier device trees. Sooner or later
the transition will be complete, Krzysztof is fixing up all of the
Qualcomm stuff, which is pretty voluminous.
Core changes:
- minor but nice and important documentation clean-ups
New drivers:
- subdriver for the Qualcomm SDM670 SoC
- subdriver for the Intel Moorefield SoC
- trivial support for the NXP Freescale i.MXRT1170 SoC
Other changes and improvements
- major clean-up of the Qualcomm pin control device tree bindings by
Krzysztof
- major header clean-up by Andy
- some immutable irqchip clean-up for the Actions Semiconductor and
Nuvoton drivers
- GPIO helpers for The Cypress cy8c95x0 driver
- bias handling in the Mediatek MT7986 driver
- remove the unused pins-are-numbered concept that never flew"

Pull spi updates from Mark Brown:
"A busy enough release, but not for the core which has only seen very
small updates. The biggest addition is the readdition of support for
detailed configuration of the timings around chip selects. That had
been removed for lack of use but there's been applications found for
it on Atmel systems. Otherwise the updates are mostly feature
additions and cleanups to existing drivers.
Summary:
- Provide a helper for getting device match data in a way that
abstracts away which firmware interface is being used.
- Re-add the spi_set_cs_timing() API for detailed configuration of
the timing around chip select and support it on Atmel.
- Support for MediaTek MT7986, Microchip PCI1xxxx, Nuvoton WPCM450
FIU and Socionext F_OSPI"

Pull regulator updates from Mark Brown:
"Quite a quiet release for regulator, the diffstat is dominated by the
I2C migration to probe_new() and the newly added MT6357 driver. We've
just one framework addition and the rest is all new device support,
fixes and cleanups.
The framework addition is an API for requesting all regulators defined
in DT, this isn't great practice but has reasonable applications when
there is generic code handling devices on buses where the bus
specification doesn't include power. The immediate application is MDIO
but I believe there's others, it's another API that'll need an eye
keeping on it for undesirable usage.
Summary:
- An API for requesting all regulators defined in DT
- Conversion of lots of drivers to the I2C probe_new() API
- Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and Richtek
