Subject: build failure after commit eb0481bbc4ce ("objtool: Fix reloc_hash
 size")

Hello,

this morning, mainline kernel builds started to fail on my desktop like
this:

  mike@...n:~/work/git/kernel-upstream> mkdir /srv/ram/kobj
  mike@...n:~/work/git/kernel-upstream> make -j24 CC=gcc-13 O=/srv/ram/kobj defconfig >/dev/null
  mike@...n:~/work/git/kernel-upstream> make -j24 CC=gcc-13 O=/srv/ram/kobj all >/dev/null

I bisected the failure to commit

  eb0481bbc4ce ("objtool: Fix reloc_hash size")

I also tried gcc11 and building on a normal filesystem (rather than
tmpfs) but the result is still the same. Different configurations (e.g.
allmodconfig) only show more modules with "mmap fail reloc". The machine
has 64 GB of RAM and both ulimit -m and ulimit -v show "unlimited".
Anything idea what else I should try?
