sg_miter_next() using an sg_mapping_iter with flag SG_MITER_ATOMIC uses kmap_atomic() to map pages. A long time ago the kmap_atomic API required a slot to be provided which risked the possibility that other code might use the same slot at the same time. Disabling interrupts prevented the possibility of an interrupt handler doing that. However, that went away with commit 3e4d3af501cc ("mm: stack based kmap_atomic()"). Remove local_irq_{save,restore}() around sg_miter_{next,stop}(). Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> --- drivers/mmc/host/sdhci.c | 10 ---------- 1 file changed, 10 deletions(-)
