I didn't see that error after I applied Linus' patch on top of v5.8.
On current mainline, I get the following error when trying to build
sparc64:allmodconfig:

include/linux/seqlock.h: In function 'write_seqcount_begin_nested':
arch/sparc/include/asm/percpu_64.h:19:25: error: '__local_per_cpu_offset' undeclared

This is caused by by commit 859247d39fb00 ("seqlock: lockdep assert non-preemptibility
on seqcount_t write").

When trying to build arm64:defconfig, I get this error:

Building arm64:defconfig ... failed
--------------
Error log:
Error: arch/arm64/boot/dts/intel/socfpga_agilex.dtsi:313.15-16 syntax error

This is caused by commit d4ae4dd346cd493 ("arm64: dts: agilex: add nand clocks").

Sigh. Anyway, after reverting those two commits on mainline (v5.8-2483-gc0842fbc1b18),
both arm64:defconfig and arm64:allmodconfig build for me (with gcc-9.3.0). Given that,
I don't think this compile problem is seen in the upstream kernel.
