Subject: linux-next: build warning from Linus' tree

Hi all,

From Linus tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

arch/x86/boot/edd.c: In function 'query_edd':
arch/x86/boot/edd.c:148:11: warning: taking address of packed member of 'struct boot_params' may result in an unaligned pointer value [-Waddress-of-packed-member]
  148 |  mbrptr = boot_params.edd_mbr_sig_buffer;
      |           ^~~~~~~~~~~

I assume this is a result of upgrading my x86_64 cross compiler to v9.2.1
(from v8.3.0).

Stephen Rothwell
