scripts/faddr2line: Fix vmlinux detection on arm64

Since commit dcea997beed6 ("faddr2line: Fix overlapping text section
failures, the sequel"), faddr2line is completely broken on arm64.

For some reason, on arm64, the vmlinux ELF object file type is ET_DYN
rather than ET_EXEC. Check for both when determining whether the object
is vmlinux.

Modules and vmlinux.o have type ET_REL on all arches.

Merge tag 'spi-nor/for-5.20' into mtd/next

SPI NOR core changes:
- move SECT_4K_PMC flag out of the core as it's a vendor specific flag
- s/addr_width/addr_nbytes: address width means the number of IO lines
used for the address, whereas in the code it is used as the number of
address bytes.
- do not change nor->addr_nbytes at SFDP parsing time. At the SFDP parsing
time we should not change members of struct spi_nor, but instead fill
members of struct spi_nor_flash_parameters which could later on be used
by the callers.
- track flash's internal address mode so that we can use 4B opcodes
together with opcodes that don't have a 4B opcode correspondent.

SPI NOR manufacturer drivers changes:
- esmt: Rename "f25l32qa" flash name to "f25l32qa-2s".
- micron-st: Skip FSR reading if SPI controller does not support it to
allow flashes that support FSR to work even when attached to such SPI
controllers.
- spansion: Add s25hl-t/s25hs-t IDs and fixups.

Pull irqchip/genirq updates from Marc Zyngier:

* Core code update:

- Non-SMP IRQ affinity fixes, allowing UP kernel to behave similarly
to SMP ones for the purpose of interrupt affinity

- Let irq_set_chip_handler_name_locked() take a const struct irq_chip *

- Tidy-up the NOMAP irqdomain API variant

- Teach action_show() to use for_each_action_of_desc()

- Make irq_chip_request_resources_parent() allow the parent callback
to be optional

- Remove dynamic allocations from populate_parent_alloc_arg()

* New drivers:

- Merge the long awaited IRQ support for the LoongArch architecture,
with the provisional ACPICA update (to be reverted once the official
support lands)

- New Renesas RZ/G2L IRQC driver, equipped with its companion GPIO
driver

* Driver updates

- Optimise the hot path operations for the SiFive PLIC, trading the
locking for per-CPU priority masking masking operations which are
apparently faster

- Work around broken PLIC implementations that deal pretty badly with
edge-triggered interrupts. Flag two implementations as affected.

- Simplify the irq-stm32-exti driver, particularly the table that
remaps the interrupts from exti to the GIC, reducing the memory usage

- Convert the ocelot irq_chip to being immutable

- Check ioremap() return value in the MIPS GIC driver

- Move MMP driver init function declarations into the common .h

- The obligatory typo fixes

faddr2line: Fix overlapping text section failures, the sequel

If a function lives in a section other than .text, but .text also exists
in the object, faddr2line may wrongly assume .text. This can result in
comically wrong output. For example:

$ scripts/faddr2line vmlinux.o enter_from_user_mode+0x1c
enter_from_user_mode+0x1c/0x30:
find_next_bit at /home/jpoimboe/git/linux/./include/linux/find.h:40
(inlined by) perf_clear_dirty_counters at /home/jpoimboe/git/linux/arch/x86/events/core.c:2504

Fix it by passing the section name to addr2line, unless the object file
is vmlinux, in which case the symbol table uses absolute addresses.

Merge tag 'objtool-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull objtool updates from Ingo Molnar:

- Comprehensive interface overhaul:
=========================

Merge tag 'objtool-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull objtool updates from Ingo Molnar:

- Comprehensive interface overhaul:
=================================

Objtool's interface has some issues:

- Several features are done unconditionally, without any way to
turn them off. Some of them might be surprising. This makes
objtool tricky to use, and prevents porting individual features
to other arches.

- The config dependencies are too coarse-grained. Objtool
enablement is tied to CONFIG_STACK_VALIDATION, but it has several
other features independent of that.

- The objtool subcmds ("check" and "orc") are clumsy: "check" is
really a subset of "orc", so it has all the same options.

The subcmd model has never really worked for objtool, as it only
has a single purpose: "do some combination of things on an object
file".

- The '--lto' and '--vmlinux' options are nonsensical and have
surprising behavior.

Overhaul the interface:

- get rid of subcmds

- make all features individually selectable

- remove and/or clarify confusing/obsolete options

- update the documentation

- fix some bugs found along the way

- Fix x32 regression

- Fix Kbuild cleanup bugs

- Add scripts/objdump-func helper script to disassemble a single
function from an object file.

- Rewrite scripts/faddr2line to be section-aware, by basing it on
'readelf', moving it away from 'nm', which doesn't handle multiple
sections well, which can result in decoding failure.

- Rewrite & fix symbol handling - which had a number of bugs wrt.
object files that don't have global symbols - which is rare but
possible. Also fix a bunch of symbol handling bugs found along the
way.
