[v1] x86/boot/e820: Assorted E820 table handling features and cleanups

[PATCH 19/32] x86/boot/e820: Change struct e820_table::nr_entries type from __u32 to u32

Posted by Ingo Molnar 7 months ago

__u32 is for UAPI headers, and this definition is the only place
in the kernel-internal E820 code that uses __u32. Change it to u32.
