+ACPICA: Clear reserved fields for incoming ACPI 1.0 FADTs
+
+Fixed a problem with the internal FADT conversion where ACPI 1.0
+FADTs that contained invalid non-zero values in reserved fields
+could cause later failures because these fields have meaning in
+later revisions of the FADT. For incoming ACPI 1.0 FADTs, these
+fields are now always zeroed. (Preferred_PM_Profile, PSTATE_CNT,
+CST_CNT, IAPC_BOOT_FLAGS.)

+These functions depend on "result" being initalized to 0, but "result"
+is not included as an input constraint to the inline assembly block
+following its initialization, only as an output constraint. Thus gcc
+thinks it doesn't need to initialize it, so result ends up undefined
+if the "unless" condition is true.
+
+This fixes an oops in sunrpc where the faulty atomics caused
+rpciod_up() to not start the workqueue as it should.

+Cc: stable@kernel.org

+
+From: Timo Jantunen <jeti@iki.fi>
+
+If the forcedeth driver receives too much work in an interrupt, it
+assumes it has a broken hardware with stuck IRQ. It works around the
+problem by disabling interrupts on the nic but makes a printk while
+holding device spinlog - which isn't smart thing to do if you have
+netconsole on the same nic.
+
+This patch moves the printk's out of the spinlock protected area.
+
+
+Without this patch the machine hangs hard. With this patch everything
+still works even when there is significant increase on CPU usage while
+using the nic.

+SATA in AHCI mode 0x4391
+SATA in non-raid5 driver 0x4392
+SATA in raid5 driver 0x4393

+
+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=3D242572).
+
+
+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).
+
+Patch in mainline as 313b0305b5a1e7e0fb39383befbf79558ce68a9c.
