[PATCH] arch: hexagon: Kconfig: add HAVE_DMA_ATTR in Kconfig and remove "linux/dma-mapping.h" from "asm/dma-mapping.h"

[PATCH] arch: hexagon: Kconfig: add HAVE_DMA_ATTR in Kconfig and remove "linux/dma-mapping.h" from "asm/dma-mapping.h"

[Chen Gang]

When HAS_DMA, and also need use generic implementation, HAVE_DMA_ATTR
must be enabled, or can not pass compiling with allmodconfig, the
related error:

    CC [M]  drivers/ata/libata-core.o
  drivers/ata/libata-core.c: In function 'ata_sg_clean':
  drivers/ata/libata-core.c:4598:3: error: implicit declaration of function 'dma_unmap_sg' [-Werror=implicit-function-declaration]
  drivers/ata/libata-core.c: In function 'ata_sg_setup':
  drivers/ata/libata-core.c:4708:2: error: implicit declaration of function 'dma_map_sg' [-Werror=implicit-function-declaration]

"linux/dma-mapping.h" will include "asm/dma-mapping.h", so need remove
"linux/dma-mapping.h" from "asm/dma-mapping.h",

[PATCH 0/2] arch: hexagon: include: asm: add prefix "vm_" for all enum members in "hexagon_vm.h"

[Chen Gang]

Append "vm_" to all enum members (which are too common to make conflict
with another sub-systems). The related error with allmodconfig:

    CC [M]  drivers/md/raid1.o

Also fix a typo issue: use 'affinity' instead of 'locdis' for

Oh, sorry, The new prefix "vm_" is still conflict with others. One case
is below (bottom of this mail)

I will use "hvmc_" for VM_CACHE_OPS and "hvmi_" for VM_INT_OPS instead
of. If get no rejections within 1 day, I will send patch v2 for it.

And also I will merge the related 2 patches together (although they are
for 2 issues).
