MEDIA_SUPPORT is set by default to m so DVB_CORE can't be y and this is
the only tristate that we set to y that is controlled by MEDIA_SUPPORT.
Change it to m. Fixes:
[NOTE]: 'CONFIG_DVB_CORE' last val (y) and .config val (m) do not match
[INFO]: CONFIG_DVB_CORE : m ## .config: 3617

When compiling xilinx-zynq board linux-kernel-dev(v5.8) if
"GCC_PLUGINS=y", The following error will appear:
"HOSTCXX -fPIC scripts/gcc-plugins/arm_ssp_per_task_plugin.o
fatal error: gmp.h: No such file or directory"
the GCC_PLUGINS depend on return result of gcc-plugin.sh

With some devices physical addresses are different than dma addresses.
To be able to deal with these cases, we need to call phys_to_dma on
physical addresses (including machine addresses in Xen terminology)
before returning them from xen_swiotlb_alloc_coherent and

It is not strictly needed. Call virt_to_phys on xen_io_tlb_start
instead. It will be useful not to have a start_dma_addr around with the
next patches.
Note that virt_to_phys is not the same as xen_virt_to_bus but actually
it is used to compared again

xen_alloc_coherent_pages might return pages for which virt_to_phys and
virt_to_page don't work, e.g. ioremap'ed pages.
So in xen_swiotlb_free_coherent we can't assume that virt_to_page works.
Instead add a is_vmalloc_addr check and use vmalloc_to_page on vmalloc

XEN_PFN_PHYS is only used in one place in swiotlb-xen making things more
complex than need to be.
Remove the definition of XEN_PFN_PHYS and open code the cast in the one
place where it is needed.

dma_cache_maint is getting called passing a dma address which could be

Add a struct device* parameter to dma_cache_maint.
Translate the dma_addr_t parameter of dma_cache_maint by calling
