Chris Metcalf 2d0186edeb __bitmap_parselist: fix bug in empty string handling ... commit 2528a8b8f457d7432552d0e2b6f0f4046bb702f4 upstream. bitmap_parselist("", &mask, nmaskbits) will erroneously set bit zero in the mask. The same bug is visible in cpumask_parselist() since it is layered on top of the bitmask code, e.g. if you boot with "isolcpus=", you will actually end up with cpu zero isolated. The bug was introduced in commit 4b060420a5 ("bitmap, irq: add smp_affinity_list interface to /proc/irq") when bitmap_parselist() was generalized to support userspace as well as kernelspace.
