Alexandre Courbot 23be7fdafa ARM: 8305/1: DMA: Fix kzalloc flags in __iommu_alloc_buffer() ... There doesn't seem to be any valid reason to allocate the pages array with the same flags as the buffer itself. Doing so can eventually lead to the following safeguard in mm/slab.c's cache_grow() to be hit: if (unlikely(flags & GFP_SLAB_BUG_MASK)) { pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK); BUG(); } This happens when buffers are allocated with __GFP_DMA32 or __GFP_HIGHMEM. Fix this by allocating the pages array with GFP_KERNEL to follow what is done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer() is safe because atomic allocations are handled by __iommu_alloc_atomic().
