[PATCH 0/2] arm64: errata: Fix two Kconfig column entries

[TAKANO Mitsuhiro]

Documentation/arch/arm64/silicon-errata.rst names two Kconfig symbols
that no Kconfig file defines.  I checked every Kconfig name in the
table: these are the only two.

The GIC-700 #2941627 entry names ARM64_ERRATUM_2941627; that workaround
is a GIC driver quirk, matched at runtime against the GIC's IIDR, so
there is no symbol to name.  The Falkor E1041 entry names
QCOM_FALKOR_ERRATUM_1041; the symbol defined in the tree is
QCOM_FALKOR_ERRATUM_E1041.

The two rows come from different commits, so they are kept separate and
each carries its own Fixes: tag.  Both are documentation-only changes:
the table keeps its column widths and no build was run.  I did not add
a Cc: stable tag, as nothing outside Documentation changes.

The changes and the changelog text were produced with an AI coding
assistant (Hermes Agent, model deepseek-v4.1-flash) working from the
tree and the git history.  I reviewed the diff and the reasoning, and I
am responsible for the submission.

[PATCH 1/2] arm64: errata: Set GIC-700 #2941627 Kconfig entry to N/A

[TAKANO Mitsuhiro]

The GIC-700 #2941627 entry in the arm64 silicon-errata table names
ARM64_ERRATUM_2941627 in its Kconfig column, but no Kconfig file defines
that symbol and no code refers to it.

The workaround has no Kconfig option: drivers/irqchip/irq-gic-v3.c
passes the GICD_IIDR value to gic_enable_quirks(), which compares it
against gic_quirks[]; the matching quirk,
gic_enable_quirk_arm64_2941627(), enables a static branch.  The table
already records GIC-driver workarounds that have no Kconfig symbol as
"N/A", for example the NVIDIA T241-FABRIC-4 row, whose workaround is
likewise in the GIC driver.

Set the Kconfig column to "N/A" for this row.  Leave the row in place: it
is the tree's only record of this erratum.

No functional change.  The change and this changelog were written with
the help of an LLM assistant (Hermes Agent); I reviewed both and am
responsible for them.

[PATCH 2/2] arm64: errata: Fix Falkor E1041 Kconfig name

[TAKANO Mitsuhiro]

The Falkor E1041 entry in the arm64 silicon-errata table names
QCOM_FALKOR_ERRATUM_1041, but the symbol is QCOM_FALKOR_ERRATUM_E1041: it
is defined in arch/arm64/Kconfig and used in
arch/arm64/include/asm/assembler.h.  Correct the name in the table.

The E1003 and E1009 rows name QCOM_FALKOR_ERRATUM_1003 and
QCOM_FALKOR_ERRATUM_1009; the E in the erratum ID is not part of either
symbol name, so an E-less name in the E1041 row looked consistent.
QCOM_FALKOR_ERRATUM_E1041 is the only Falkor symbol that carries the E.

The Kconfig symbol is correct; only the table entry is wrong.

No functional change.  The change and this changelog were written with
the help of an LLM assistant (Hermes Agent); I reviewed both and am
responsible for them.

[PATCH 0/2] arm64: errata: Fix two Kconfig column entries

[TAKANO Mitsuhiro]

Two entries in the arm64 silicon-errata table name Kconfig symbols that
do not exist.  The GIC-700 #2941627 row names ARM64_ERRATUM_2941627, but
the workaround has no Kconfig option at all; it is enabled from
irq-gic-v3.c through gic_enable_quirks().  The Falkor E1041 row spells
QCOM_FALKOR_ERRATUM_E1041 without the E.

The first patch marks the GIC-700 row "N/A", matching other workarounds
that have no option.  The second corrects the Falkor symbol name.  Both
changes touch only the text of the table; no Kconfig symbol or code
changes, and no build was run.

Sorry for the noise.
