Just on a note on that mail: gk...@linux.vnet.ibm.com has no longer been

What is this patch supposed to be doing?
What bug is it fixing?
This information is part in the first message of this mail thread.
The patch was intendedfor the active discussion in this thread,
not for a broad review.

It seems some optimization has been removed from the code without removing
the if condition which should activate it only on 64-bit platforms and as

idr_get_next() gives WARN_ON_ONCE() when it gets (id > INT_MAX) true
and this happens when syzbot does fuzzing, and that warning is
expected, but WARN_ON_ONCE() is not required here and, cecking
the condition and returning NULL value would be suffice.

The current implementation reduces the sampling rate by half

Hi all,
this series adds range-based offsets to the dma-direct implementation. The
guts of the change are a patch from Jim with some modifications from me,
but to do it nicely we need to ARM patches to prepare for it as well.
Changes since v1:
- rebased on top of the latests dma-mapping
The __arch_page_to_dma hook is long gone.

This comment is outdated and no longer reflects the actual implementation
of af_packet.c.
Reasons for the new comment:
1.
In af_packet.c, the function packet_snd first reserves a headroom of
length (dev->hard_header_len + dev->needed_headroom).
Then if the socket is a SOCK_DGRAM socket, it
Move the helpers to translate to and from direct mapping DMA addresses
to dma-direct.h. This not only is the most logical place, but the new
placement also avoids dependency loops with pending commits.

The DMA offset notifier can only be used if PHYS_OFFSET is at least
KEYSTONE_HIGH_PHYS_START, which can't be represented by a 32-bit
phys_addr_t. Currently the code compiles fine despite that, a pending
change to the DMA offset handling would create a compiler warning for
this case. Add an ifdef
