[PATCH v4 11/12] x86: reserve setup_data ranges late after parsing memmap cmdline

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Kdump kernel using memmap=exactmap, move e820_reserve_setup_data after
parsing early params so they can be set reserved finally. Or kdump kernel
will warn about ioremap a normal ram range.
