We had another incident with new net code poking into dma internals
blocking this series. That is now sorted out, so the series is back
on track.

Struct headers require a 'struct $NAME' title, all function parameters
require a description and need to be in the format '@.*:', else the
checker gets confused. Also demote one kerneldoc header where no effort
was made to document any of the function's params.

Hi Michael,
I see this patch is marked as "defered" in patchwork, but I can't see
any related discussion. Is it normal ?
Because it uses the "m<>" constraint which didn't work on GCC 4.6.
Since commit ("1bd79336a426 powerpc: Fix various
syscall/signal/swapcontext bugs"), getting save_general_regs() called
without FULL_REGS() is very unlikely and generates a warning.
The 32-bit version of save_general_regs() doesn't take care of it
at all and copies all registers anyway since that c
save_general_regs() which does special handling when i == PT_SOFTE.
Rewrite it to minimise the specific part, especially the __put_user()
and associated error handling is the same so make it common.
