cpufreq: interactive: apply intermediate load to max speed not current

Evaluate spikes in load (below go_hispeed_load) against the maximum
speed supported by the device, not the current speed (which tends to
make it too difficult to raise speed to intermediate levels until
very busy).

cpufreq: interactive: set at least hispeed when above hispeed load

If load is above go_hispeed_load, always go to at least hispeed_freq,
even when reducing speed from a higher speed, not just when jumping
up from minimum speed.  Avoids running at a lower than intended
speed after a burst of even higher load.

Apply min_sample_time to the last time the current target speed
was originally requested or re-validated as appropriate for the
current load, not to the time since the current speed was

loads.

x86 bpf_jit: fix a bug in emitting the 16-bit immediate operand of AND

[ Upstream commit 1d24fb3684f347226747c6b11ea426b7b992694e ]

When K >= 0xFFFF0000, AND needs the two least significant bytes of K as
its operand, but EMIT2() gives it the least significant byte of K and
0x2. EMIT() should be used here to replace EMIT2().

[ Upstream commit 81213b5e8ae68e204aa7a3f83c4f9100405dbff9 ]

If both addresses equal, nothing needs to be done. If the device is down,
then we simply copy the new address to dev->dev_addr. If the device is up,
then we add another loopback device with the new address, and if that does
not fail, we remove the loopback device with the old address. And only
then, we update the dev->dev_addr.

Make CDC EEM recalculate the hard_mtu after adjusting the

Without this, usbnet adjusts the MTU down to 1494 bytes, and the host is

mtd: sst25l: initialize writebufsize

commit c4cc625ea5958d065c21cc0fcea29e9ed8f3d2bc upstream.

The writebufsize concept was introduce by commit
"0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents
the maximum amount of data the device writes to the media at a time. This is
an important parameter for UBIFS which is used during recovery and which
basically defines how big a corruption caused by a power cut can be.

Set writebufsize to the flash page size because it is the maximum amount of
data it writes at a time.

commit b54f47c8bcfc5f766bf13ec31bd7dd1d4726d33b upstream.

Using UBI on m25p80 can give messages like:

    UBI error: io_init: bad write buffer size 0 for 1 min. I/O unit

We need to initialize writebufsize; I think "page_size" is the correct
"bufsize", although I'm not sure. Comments?

ACPI: Do cpufreq clamping for throttling per package v2

commit 2815ab92ba3ab27556212cc306288dc95692824b upstream.

On Intel CPUs the processor typically uses the highest frequency
set by any logical CPU. When the system overheats
Linux first forces the frequency to the lowest available one
to lower the temperature.

However this was done only per logical CPU, which means all
logical CPUs in a package would need to go through this before
the frequency is actually lowered.

Worse this delay actually prevents real throttling, because
the real throttle code only proceeds when the lowest frequency
is already reached.

So when a throttle event happens force the lowest frequency
for all CPUs in the package where it happened. The per CPU
state is now kept per package, not per logical CPU. An alternative
would be to do it per cpufreq unit, but since we want to bring
down the temperature of the complete chip it's better
to do it for all.

In principle it may even make sense to do it for all CPUs,
but I kept it on the package for now.

With this change the frequency is actually lowered, which
in terms also allows real throttling to proceed.

I also removed an unnecessary per cpu variable initialization.

PNPACPI: Fix device ref leaking in acpi_pnp_match

commit 89e96ada572fb216e582dbe3f64e1a6939a37f74 upstream.

During testing pci root bus removal, found some root bus bridge is not freed.
If booting with pnpacpi=off, those hostbridge could be freed without problem.
It turns out that some devices reference are not released during acpi_pnp_match.
that match should not hold one device ref during every calling.
Add pu_device calling before returning.

ACPICA: Fix regression in FADT revision checks

commit 3e80acd1af40fcd91a200b0416a7616b20c5d647 upstream.

	commit 64b3db22c04586997ab4be46dd5a5b99f8a2d390 (2.6.39),
"Remove use of unreliable FADT revision field" causes regression
for old P4 systems because now cst_control and other fields are
not reset to 0.

	The effect is that acpi_processor_power_init will notice
cst_control != 0 and a write to CST_CNT register is performed
that should not happen. As result, the system oopses after the
"No _CST, giving up" message, sometimes in acpi_ns_internalize_name,
sometimes in acpi_ns_get_type, usually at random places. May be
during migration to CPU 1 in acpi_processor_get_throttling.

	Every one of these settings help to avoid this problem:
 - acpi=off
 - processor.nocst=1
 - maxcpus=1

	The fix is to update acpi_gbl_FADT.header.length after
the original value is used to check for old revisions.

genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return value

commit f5cb92ac82d06cb583c1f66666314c5c0a4d7913 upstream.

irq_move_masked_irq() checks the return code of
chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is
also a valid return code, which is there to avoid a redundant copy of
the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid
the redundant copy, we also fail to adjust the thread affinity of an
eventually threaded interrupt handler.

Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return
values correctly by checking the valid return values seperately.
