6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anshuman Khandual <anshuman.khandual@arm.com>
commit 858c7bfcb35e1100b58bb63c9f562d86e09418d9 upstream.
FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1
access from EL1 requires appropriate EL2 fine grained trap configuration
via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2.
Otherwise such register accesses will result in traps into EL2.
Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine
grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the
bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into
PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers.
Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2
based registers to be accessible in EL2.

Slackware64-current).
I noticed that in 2 of 3 reboots X is slow to start (but is usable) and in dmesg I found this:

This patch was already in 6.12.24, and it is now twice in 6.12.y.
3802df8552de kbuild: Add '-fno-builtin-wcslen'
9c03f6194e88 kbuild: Add '-fno-builtin-wcslen'
and
$ grep fno-builtin-wcslen Makefile
KBUILD_CFLAGS += -fno-builtin-wcslen
KBUILD_CFLAGS += -fno-builtin-wcslen
This is the second time this happened in the 6.12 series. The other sequence is
61749c035911 Revert "vfio/platform: check the bounds of read/write syscalls"
61ba518195d6 vfio/platform: check the bounds of read/write syscalls
a20fcaa230f7 vfio/platform: check the bounds of read/write syscalls
Would it be possible to avoid those duplicates ? It doesn't matter in
the above cases, but we might not always be that lucky.
Thanks,
Guenter

Sorry about that, it's not a normal thing, and yes, our scripts should
check it. I'll work on adding it in the future, thanks.
