Currently, most of the MMU-specific code is in mm.{c,h}. To make the

The original assembly setup_fixmap() is actually doing two seperate

I was just going to apply this, but patch 1 seems to have a non-trivial
conflict with the is_swiotlb_active removal in pci-dma.c. Can you resend
against the current dma-mapping for-next tree?

Hi,
this is a patch set to clean up the PCM copy ops using sockptr_t as a
"universal" pointer, inspired by the recent patch from Andy
Shevchenko:
https://lore.kernel.org/r/20230721100146.67293-1-andriy.shevche...@linux.intel.com
Even though it sounds a bit weird, sockptr_t is a generic type
This patch converts the xen frontend driver code to use the new
unified PCM copy callback. It's a straightforward conversion from
*_user() to *_sockptr() variants.
