hi,
new version of pahole (1.24) is causing compilation fail for 5.10
stable kernel, discussed in here [1][2]. Sending fix for that plus
dependency patches.
thanks,

commit db16c1fe92d7ba7d39061faef897842baee2c887 upstream.
[backported for dependency only extra_paholeopt variable setup and
usage, we don't want floats generated in 5.10]
pahole v1.21 supports the --btf_gen_floats flag, which makes it
generate the information about the floating-point types [1].
Adjust link-vmlinux.sh to pass this flag to pahole in case it's
supported, which is determined using a simple version check.

commit ff2e6efda0d5c51b33e2bcc0b0b981ac0a0ef214 upstream.
[backported for dependency, skipped Makefile.modfinal change,
because module BTF is not supported in 5.10]
The ccache tool can be used to speed up cross-compilation, by calling the
compiler and binutils through ccache. For example, following should work:
$ export ARCH=arm64 CROSS_COMPILE="ccache aarch64-linux-gnu-"
$ make M=drivers/gpu/drm/rockchip/
but pahole fails to extract the BTF info from DWARF, breaking the build:
CC [M] drivers/gpu/drm/rockchip//rockchipdrm.mod.o
LD [M] drivers/gpu/drm/rockchip//rockchipdrm.ko
BTF [M] drivers/gpu/drm/rockchip//rockchipdrm.ko
aarch64-linux-gnu-objcopy: invalid option -- 'J'
Usage: aarch64-linux-gnu-objcopy [option(s)] in-file [out-file]
Copies a binary file, possibly transforming it in the process
...
make[1]: *** [scripts/Makefile.modpost:156: __modpost] Error 2
make: *** [Makefile:1866: modules] Error 2
this fails because OBJCOPY is set to "ccache aarch64-linux-gnu-copy" and
later pahole is executed with the following command line:
LLVM_OBJCOPY=$(OBJCOPY) $(PAHOLE) -J --btf_base vmlinux $@
which gets expanded to:
LLVM_OBJCOPY=ccache aarch64-linux-gnu-objcopy pahole -J ...
instead of:
LLVM_OBJCOPY="ccache aarch64-linux-gnu-objcopy" pahole -J ...
Fixes: 5f9ae91f7c0d ("kbuild: Build kernel module BTFs if BTF is enabled and pahole supports it")

commit a0b8200d06ad6450c179407baa5f0f52f8cfcc97 upstream.
[small context changes due to missing floats support in 5.10]
Commit "mm/page_alloc: convert per-cpu list protection to local_lock" will
introduce a zero-sized per-CPU variable, which causes pahole to generate
invalid BTF. Only pahole versions 1.18 through 1.21 are impacted, as
before 1.18 pahole doesn't know anything about per-CPU variables, and 1.22
contains the proper fix for the issue.
Luckily, pahole 1.18 got --skip_encoding_btf_vars option disabling BTF
generation for per-CPU variables in anticipation of some unanticipated
problems. So use this escape hatch to disable per-CPU var BTF info on
those problematic pahole versions. Users relying on availability of
per-CPU var BTFs would need to upgrade to pahole 1.22+, but everyone won't
notice any regressions.

New pahole (version 1.24) generates by default new BTF_KIND_ENUM64 BTF tag,
which is not supported by stable kernel.
As a result the kernel with CONFIG_DEBUG_INFO_BTF option will fail to
compile with following error:
BTFIDS vmlinux
FAILED: load BTF from vmlinux: Invalid argument
New pahole provides --skip_encoding_btf_enum64 option to skip BTF_KIND_ENUM64
generation and produce BTF supported by stable kernel.
Adding this option to scripts/pahole-flags.sh.
This change does not have equivalent commit in linus tree, because linus tree
has support for BTF_KIND_ENUM64 tag, so it does not need to be disabled.

lore.kernel.org:

hum, the 'git send-email' log says it was sent to stable@vger.kernel.org
(plus other emails) all with no problem.. maybe some mailing list hiccup?
I'd give it some time
