[PATCH] x86/efi: Free efi_pgd with free_pages()

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

 



This patch fixes another occurrence of free_page() that was missed
in 06ace26.
The efi_pgd is allocated as PGD_ALLOCATION_ORDER pages and therefore must
also be freed as PGD_ALLOCATION_ORDER pages with free_pages().
