I get an "out of memory" error when building Linux kernels 5.15.164,
5.15.165 and 5.15.166-rc1:

#uname -a
Linux aragorn 5.15.166-rc1-smp #1 SMP PREEMPT Mon Sep 2 14:03:00 PDT 2024
i686 AMD Ryzen 9 5900X 12-Core Processor AuthenticAMD GNU/Linux

Attached is my config file.

I found a work around for this problem.

Remove the six minmax patches introduced with kernel 5.15.164:

minmax: allow comparisons of 'int' against 'unsigned char/short'
minmax: allow min()/max()/clamp() if the arguments have the same
minmax: clamp more efficiently by avoiding extra comparison
minmax: fix header inclusions
minmax: relax check to allow comparison between unsigned arguments
minmax: sanity check constant bounds when clamping

Can these 6 patches be removed or fixed?
