Will Deacon 9af386c8dc ARM: 6890/1: memmap: only free allocated memmap entries when using SPARSEMEM ... The SPARSEMEM code allocates memmap entries only for sections which are present (i.e. those which contain some valid memory). The membank checks in free_unused_memmap do not take this into account and can incorrectly attempt to free memory which is not allocated, resulting in a BUG() in the bootmem code. However, if memory is configured as follows: |<----section---->|<----hole---->|<----section---->| +--------+--------+--------------+--------+--------+ | bank 0 | unused | | bank 1 | unused | +--------+--------+--------------+--------+--------+ where a bank only occupies part of a section, the memmap allocated for the remainder of the section *can* be freed. This patch modifies the checks in free_unused_memmap so that only valid memmap entries are considered for removal.
