So currently it seems to be hanging when checking drivers/clk/clk.c
doing the following.
$ make C=1 drivers/clk/clk.o
This is working under v6.19 and not under v7.0-rc1
The git bisect is pointing to this commit
commit e19e1b480ac73c3e62ffebbca1174f0f511f43e7
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Sat Feb 21 16:14:11 2026 -0800
add default_gfp() helper macro and use it in the new *alloc_obj()
helpers

The stderr output before it hangs is:
