memblock: drop memblock_alloc_*_nopanic() variants

2019-03-12T17:04:02Z

As all the memblock allocation functions return NULL in case of error rather than panic(), the duplicates with _nopanic suffix can be removed.

efi: cper: Fix possible out-of-bounds access

2019-02-20T09:34:35Z

When checking a generic status block, we iterate over all the generic data blocks. The loop condition only checks that the start of the generic data block is valid (within estatus->data_length) but not the whole block. Because the size of data blocks (excluding error data) may vary depending on the revision and the revision is contained within the data block, ensure that enough of the current data block is valid before dereferencing any members otherwise an out-of-bounds access may occur if estatus->data_length is invalid. This relies on the fact that struct acpi_hest_generic_data_v300 is a superset of the earlier version. Also rework the other checks to avoid potential underflow.
