Slow night -- time for a [Build Report] for Linux 6.15

Linux 6.15 has been released.

$ uname -a
Linux lm 6.15.0 #1 SMP PREEMPT Mon May 26 22:25:03 PDT 2025 x86_64 x86_64 x86_64 GNU/Linux

real 416.11
user 19116.13
sys 3931.93

To get the NVIDIA driver to work with it, I had to install it
with two flags:

nvidia-installer command line:
./nvidia-installer
–no-unified-memory
–skip-module-load

This is because the unified memory module won't build.  (I tried
the MIT/GPL branch, didn't try the proprietary branch.)

Without unified memory, CUDA won't work.  So I'm out of luck there
until they fix it.  Here is the error:

   In file included from nvidia-uvm/uvm_va_block_types.h:27,
