[PULL 7/7] m68k: import bootinfo headers from linux |
|
Date: |
Fri, 12 Feb 2021 22:14:48 +0100 |
Copy bootinfo.h and bootinfo-mac.h from arch/m68k/include/uapi/asm/
to include/standard-headers/asm-m68k/
Imported from linux v5.9 but didn't change since v4.14 (header update)
and since v4.10 (content update).
