Hello,

on ARM using dfu mode we've seen problems with dma memory allocations.
Some drivers use dma_inv_range on allocated buffers, which corrupts memory
around the buffer, it it's not aligned to cache lines. This series
introduces: dma_alloc() and dma_free() that allocate memory aligned to
cache lines. This is 64 bytes on ARM (just to be sure) and
DCACHE_LINE_SIZE on nios2. All other arch do a transparent xmalloc.

Feel free to add the appropriate alignment for your architecture to
"include/asm/dma.h"

regards, Marc

dma_alloc() allocates memory aligned to cache lines. We have to use
cache line aligned buffers if a driver calls dma_inv_range on the
buffer. Add dma_free() for documentation reasons, too.

Some drivers call dma_inv_range() on buffers, on arm these buffers must
be cache line aligned. This patch introduces transparent dma_alloc,
dma_free for blackfin, mips, openrisc, ppc, sandbox, x86 architectures
which translate into xmemalign and free. The arm version uses xmemalign.

The fsl udc driver allocates a buffer for small requests. The
driver then calls dma_inv_range later on it. This buffer happens
to be not cacheline aligned which means that a dma_inv_range can
corrupt other memory around the buffer.

Marc Kleine-Budde (4):
      ARM mmu: don't use CONFIG_MMU to disable mmu code, there are static inline versions
      ARM mmu: introduce dma_alloc, dma_free
      nios: add dma_alloc, dma_free and asm/dma.h
      blackfin, mips, openrisc, ppc, sandbox, x86: add transparent dma_alloc, dma_free inlines

Sascha Hauer (2):
      USB gadget fsl: request cacheline aligned buffer
      USB gadget: Fix dma memory allocations
