avoid endless loops in lib/swiotlb.c
Commit 681cc5cd3efbeafca6386114070e0bfb5012e249 ("iommu sg merging: swiotlb: respect the segment boundary limits") introduced two possibilities for entering an endless loop in lib/swiotlb.c: - if max_slots is zero (possible if mask is ~0UL) - if the number of slots requested fits into a swiotlb segment, but is too large for the part of a segment which remains after considering offset_slots This fixes them Signed-off-by: Jan Beulich <jbeulich@novell.com> Cc: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
