r8169: avoid needless NAPI poll scheduling

Theory  : though needless, it should not have hurt.
Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP
(see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242572).

The patch makes sense in itself but I should dig why it has an effect
on #242572 (assuming that NAPI do not change in a near future).

Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n.  Fix this

LGUEST && BLOCK.  Do the same for the net driver, rather then depending

Introduce CONFIG_SUSPEND for suspend-to-Ram and standby

Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.

Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).

There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

Provide timespec to guests rather than jiffies clock.

A non-periodic clock_event_device and the "jiffies" clock don't mix well:
tick_handle_periodic() can go into an infinite loop.

Currently lguest guests use the jiffies clock when the TSC is
unusable.  Instead, make the Host write the current time into the lguest
page on every interrupt.  This doesn't cost much but is more precise
and at least as accurate as the jiffies clock.  It also gets rid of
the GET_WALLCLOCK hypercall.

Also, delay setting sched_clock until our clock is set up, otherwise
the early printk timestamps can go backwards (not harmful, just ugly).

Removing processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.

Salyzyn, Mark [Fri, 27 Jul 2007 14:29:26 +0000 (10:29 -0400)]
[SCSI] aacraid: fix Sunrise Lake reset handling

The patch is *much* smaller than the description. I am attempting to
answer to those that want to understand an issue that was reported in
May this year.

If a Sunrise Lake based card that requires an alternate reset mechanism
is set up to ignore the commanded IOP_RESET it reports 0x00000010
(IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism
to reset all cores), and thus the reset platform function decides to
switch to IOP_RESET_ALWAYS because the reset platform function
parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS
then responds with the 0x3803000F return code, but alas we treat this as
an error instead of using the alternate reset mechanism (put a 0x03 into
the register offset 0x38). The reset fails, but the fact that the
IOP_RESET_ALWAYS command was issued has put the card in a purposeful
shutdown state in preparation for the alternate hardware reset to be
applied. Yuck.

IOP_RESET is ignored in internal production cards, typically to ensure
that we catch all adapter lockup issues without the driver progressing
further, so this would not appear to be a field issue and thus this
patch was destined to be only in the internal Adaptec source tree.
IOP_RESET_ALWAYS is reserved for
kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as
expected in any case. Also in the past we have had OEMs specifically
request that cards not be resetable after a BlinkLED/FirmwareAssert for
one reason or another and To head off the possibility that the Sunrise
Lake based cards would suffer a similar fate, we propose the enclosed
fix.

Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when
he reported an issue to the linux kernel list back in May regarding a
kexec problem resulting from this reset being ignore. His fix was to
update the Firmware to one that did not ignore the IOP_RESET. Previous
kernels did not attempt to reset the adapter and that is why it surfaced
as a regression in his hands.

The current list of aacraid based cards that use Sunrise Lake:

17 years ago[S390] Fix IRQ tracing.
Heiko Carstens [Fri, 27 Jul 2007 10:29:18 +0000 (12:29 +0200)]
[S390] Fix IRQ tracing.

If a machine check is pending and the external or I/O interrupt handler
returns to userspace io_mcck_pending is going to call s390_handle_mcck.
Before this happens a call to TRACE_IRQS_ON was already made since we
know that we are going back to userspace and hence interrupts will be
enabled. So there was an indication that interrupts are enabled while
in reality they are still disabled.
s390_handle_mcck will do a local_irq_save/restore pair and confuse
lockdep which later complains about inconsistent irq tracing.
To solve this just call trace_hardirqs_off before calling
s390_handle_mcck and trace_hardirqs_on afterwards.
