[patch 1/6] PS3: Remove dev_dbg redefinition in ehci-ps3.c and ohci-ps3.c

[patch 1/6] PS3: Remove dev_dbg redefinition in ehci-ps3.c and ohci-ps3.c

[Geoff Levand]

Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition
of dev_dbg in the !DEBUG case from being a #define to being a static
inline.  There was code in usb/host/ehci-ps3.c and ohci-ps3.c to do
exactly that, which fails to compile now.  This fixes it by removing
the redefinition, as the redefinition is now superfluous.

[patch 5/6] PS3: Fix system slowdown

[Geoff Levand]

From: Takao Shinohara <shin@sm.sony.co.jp>

The PS3 HV will deliver soft-disabled interrupts at the next HV call or
interrupt.  Add an HV call to local_irq_restore() to force the timely
delivery of any pending interrupts.

This fixes the system slowdown bug reported here
http://bugzilla.kernel.org/show_bug.cgi?id=8260

From: Takao Shinohara <shin@sm.sony.co.jp>
Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com>
---

I made a request to change the behavior of the lv1 hypervisor to better
support the way we do soft-disable on Linux, but it is still not been
decided if and when that support will be done.

Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Note: It would be nicer to do the HV call from assembly, using a
firmware feature section, when the interrupt actually happens. The main
reason I haven't done a patch yet is that it happens in an exception
vectors with only few registers available nad the HV call will clobber a
lot more than we have saved.
