I was hoping the PASEMI / NXP regressions could be solved before

This patch replaces calls to spi_read() and spi_write() by
spi_write_then_read() which doesn't require DMA-safe buffers.

Arch code should use tracehook_*() helpers, as documented
in include/linux/tracehook.h,
ptrace_report_syscall() is not expected to be used outside that file.
The patch does not look very nice, but at least it is correct
and opens the way for PTRACE_GET_SYSCALL_INFO API.

Michael,
I have been wondering for a while now, but I failed to make sense of
this function: pt_regs_check (commit 002af9391bfbe). What is this
function meant for ?
Background, it breaks my W=1 build with:
