-Adjust link-vmlinux.sh to pass this flag to pahole in case it's

-
-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.

-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 ...
-

-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.
