commit 2a15cd2ff488a9fdb55e5e34060f499853b27c77 upstream.
With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.Reported-by: Sameer Nanda

commit 62fb376e214d3c1bfdf6fbb77dac162f6da04d7e upstream.
mplayer -vo fbdev tries to create a screen that is twice as tall as the
allocated framebuffer for "doublebuffering". By default, and all in-tree
users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer
originally allocated.References: https://bugs.freedesktop.org/show_bug.cgi?id=38138

In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit a9b89e2) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.Driver rtl8192de also has the same code structure - this one is fixed as well.

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=1The fix is to update acpi_gbl_FADT.header.length after
the original value is used to check for old revisions.https://bugzilla.kernel.org/show_bug.cgi?id=42700

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.

commit c9651e70ad0aa499814817cbf3cc1d0b806ed3a1 upstream.
Since 3.2.12 and 3.3, some systems are failing to boot with a BUG_ON.
Some other systems using the pata_jmicron driver fail to boot because no
disks are detected. Passing pcie_aspm=force on the kernel command line
works around it.The cause: commit 4949be16822e ("PCI: ignore pre-1.1 ASPM quirking when
ASPM is disabled") changed the behaviour of pcie_aspm_sanity_check() to
always return 0 if aspm is disabled, in order to avoid cases where we
changed ASPM state on pre-PCIe 1.1 devices.This skipped the secondary function of pcie_aspm_sanity_check which was
to avoid us enabling ASPM on devices that had non-PCIe children, causing
trouble later on. Move the aspm_disabled check so we continue to honour
that scenario.Addresses https://bugzilla.kernel.org/show_bug.cgi?id=42979 and

commit 49d4bcaddca977fffdea8b0b71f6e5da96dac78e upstream.
When DMA is enabled, sh-sci transfer begins with
uart_start()
sci_start_tx()
if (cookie_tx < 0) schedule_work()
Then, starts DMA when wq scheduled, -- (A)
process_one_work()
work_fn_rx()
cookie_tx = desc->submit_tx()
And finishes when DMA transfer ends, -- (B)
sci_dma_tx_complete()
async_tx_ack()
cookie_tx = -EINVAL
(possible another schedule_work())This A to B sequence is not reentrant, since controlling variables
(for example, cookie_tx above) are not queues nor lists. So, they
must be invoked as A B A B..., otherwise results in kernel crash.To ensure the sequence, sci_start_tx() seems to test if cookie_tx < 0
(represents "not used") to call schedule_work().
But cookie_tx will not be set (to a cookie, also means "used") until
in the middle of work queue scheduled function work_fn_tx().This gap between the test and set allows the breakage of the sequence
under the very frequently call of uart_start().
Another gap between async_tx_ack() and another schedule_work() results
in the same issue, too.This patch introduces a new condition "cookie_tx == 0" just to mark
it is "busy" and assign it within spin-locked region to fill the gaps.Signed-off-by: Takashi Yoshii

commit aeb2deae2660a1773c83d3c6e9e6575daa3855d6 upstream.
This patch fixes a possible deadlock in dm-crypt's mempool use.
Currently, dm-crypt reserves a mempool of MIN_BIO_PAGES reserved pages.
It allocates first MIN_BIO_PAGES with non-failing allocation (the allocation
cannot fail and waits until the mempool is refilled). Further pages are
allocated with different gfp flags that allow failing.Because allocations may be done in parallel, this code can deadlock. Example:
There are two processes, each tries to allocate MIN_BIO_PAGES and the processes
run simultaneously.
It may end up in a situation where each process allocates (MIN_BIO_PAGES / 2)
pages. The mempool is exhausted. Each process waits for more pages to be freed
to the mempool, which never happens.To avoid this deadlock scenario, this patch changes the code so that only
the first page is allocated with non-failing gfp mask. Allocation of further
pages may fail.Signed-off-by: Mikulas Patocka

commit 8276536cec38bc6bde30d0aa67716f22b9b9705a upstream.
This function should be capable of both enabling and disabling interrupts
based upon the *enable* parameter. Right now the function only enables
the interrupt and *enable* is not used at all. So add the interrupt
disable capability also using the parameter.Signed-off-by: Tarun Kanti DebBarma

commit 9ab2393fc3e460cd2040de1483918eb17abb822f upstream.
The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner
instead of a tda18271c1 tuner as used in revision D1E9. To
account for this, we must hardcode the frontend configuration
to use the same IF frequency configuration for both revisions
of the device.6MHz DVB-T is unaffected by this issue, as the recommended
IF Frequency configuration for 6MHz DVB-T is the same on both
c1 and c2 revisions of the tda18271 tuner.Signed-off-by: Michael Krufky

commit 34817174fca0c5512c2d5b6ea0fc37a0337ce1d8 upstream.
The error handling in lgdt3303_read_status() and lgdt330x_read_ucblocks()
doesn't work, because i2c_read_demod_bytes() returns a u8 and (err < 0)
is always false.err = i2c_read_demod_bytes(state, 0x58, buf, 1);
if (err < 0)
return err;Change the return type of i2c_read_demod_bytes() to int. Also change
the return value on error to -EIO to make (err < 0) work.Signed-off-by: Xi Wang
