Hi,
I checked the arch/x86/platform/efi/early_printk.c.
In early_efi_scroll_up(), 2 mapping entries will be used for the src/dst screen
buffer.
In drivers/acpi/acpica/tbutils.c, we've improved the early table loading code
in acpi_tb_parse_root_table().
We now need 2 mapping entries:
1. One mappi
Hi,
There is only limited entries in the x86 early mapping which is implemented by
the FIXMAP.
So this means for all __init call invoked for x86, if there was a early mapping
in it, it should be unmapped before exiting the __init call.
Using this rule, all __init call implementers can make sure
