x86_64: remove bogus optimization in sysret_signal
This short-circuit path in sysret_signal looks wrong to me.
AFAICT, in practice the branch is never taken--and if it were,
it would go wrong. To wit, try loading a module whose init
function does set_thread_flag(TIF_IRET), and see insmod crash
(presumably with a wrong user stack pointer).
This is because the FIXUP_TOP_OF_STACK work hasn't been done yet
when we jump around the call to ptregscall_common and get to
int_with_check--where it expects the user RSP,SS,CS and EFLAGS to
have been stored by FIXUP_TOP_OF_STACK.
I don't think it's normally possible to get to sysret_signal with no
_TIF_DO_NOTIFY_MASK bits set anyway, so these two instructions are
already superfluous. If it ever did happen, it is harmless to call
do_notify_resume with nothing for it to do.

* Filter out "default" transfer mode values (0x00 - default PIO mode,

Allowing "default" transfer mode values is a dangerous thing to do as
we don't support programming controller to the "default" transfer mode
and devices often use different values for the default and maximum PIO
mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
programmed for higher PIO mode while device will use the lower PIO mode.
There is no functionality loss as by using special IOCTLs device can
still be programmed to "default" transfer modes (it is only useful for
debugging/testing purposes anyway).
* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was

ide: add ->read_sff_dma_status method
Add ->read_sff_dma_status method for reading DMA Status register
and use it instead of ->INB.
While at it:
* Use inb() directly in ns87415.c::ns87415_dma_end().
There should be no functional changes caused by this patch.

ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use
it instead of calling ide_init_port_hw() directly.
[ However if host has > 1 port we must still set hwif->chipset to hint
consecutive ide_find_port() call that the previous slot is occupied. ]
* Unexport ide_init_port_hw().
v2:
* Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
(Suggested by Geert Uytterhoeven)
* Better patch description.
v3:
* Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)
There should be no functional changes caused by this patch.

Move ide_find_port() call to pmac_ide_setup_device().
While at it:
- fix return value (s/-ENODEV/-ENOENT/)
- add DRV_NAME define and use it to set name field of pmac_port_info
- use ide_find_port_slot() instead of ide_find_port()
- remove superfluous error message (ide_find_port_slot() takes care of it)
- drop IDE interface number from driver banner message (but include bus type)
v2:
* Build fix (thanks to Stephen Rothwell for noticing the issue).

UML - Fix boot crash
My copying of linux/init.h didn't go far enough. The definition of
__used singled out gcc minor version 3, but didn't care what the major
version was. This broke when unit-at-a-time was added and gcc started
throwing out initcalls.
This results in an early boot crash when ptrace tries to initialize a
process with an empty, uninitialized register set.
