The brcmsmac driver is now using the bcma SPROM CRC check, which does
not recognize all chipsets that were functional prior to the switch. In
particular, the current code bails out on odd CRC errors in recent
Macbooks. This patch ignores those errors, with the argument that an
unrecognized SPROM should be treated similarly to a non-existing one.

commit adb5066 "ath9k_hw: do not apply the 2.4 ghz ack timeout
workaround to cts" reduced the hardware CTS timeout to the normal
values specified by the standard, but it turns out while it doesn't
need the same extra time that it needs for the ACK timeout, it
does need more than the value specified in the standard, but only
for 2.4 GHz.
This patch brings the CTS timeout value in sync with the initialization
values, while still allowing adjustment for bigger distances.

commit b4a82a0 "ath9k_hw: fix interpretation of the rx KeyMiss flag"
fixed the interpretation of the KeyMiss flag for keycache based lookups,
however WEP encryption uses a static index, so KeyMiss is always asserted
for it, even though frames are decrypted properly.
Fix this by clearing the ATH9K_RXERR_KEYMISS flag if no keycache based
lookup was performed.

This patch addresses a kernel bugzilla report and two recent mail threads.
The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.
The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.
The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.
This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

Fix multiple bugs in event tracing:
1) If you enable uCode tracing with the device down,
it will still attempt to access the device and
continuously log "MAC is in deep sleep!" errors.
Fix this by only starting logging when the device
is actually alive.
2) Now you can set the flag when the device is down,
but logging doesn't happen when you bring it up.
To fix that, start logging when the device comes
alive. This means we don't log before -- we could
do that but I don't need it right now.
3) For some reason we read the error instead of the
event log -- use the right pointer.
4) Optimise SRAM reading of event log header.
5) Fix reading write pointer == capacity, which can
happen due to racy SRAM access
6) Most importantly: fix an error where we would try
to read WAY too many events (like 2^32-300) when
we read the wrap counter before it is updated by
the uCode -- this does happen in practice and will
cause the driver to hang the machine.
7) Finally, change the timer to 10ms instead of 100ms
as 100ms is too slow to capture all data with a
normal event log and with 100ms the log will wrap
multiple times before we have a chance to read it.

For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.
In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.
This patch adds,
* New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
WMI event table.
* New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()

First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.
Summary of changes:
* ath6kl_wow_ap() is added to configure the below default
patterns when the system enters into WOW suspend in AP mode.
+ Unicast IP, EAPOL-like and ARP packet pattern
+ ARP packet pattern
+ mDNS/SSDP/LLMNR pattern
+ DHCP broadcast pattern
* ath6kl_wow_sta() is added to configure the below default
patterns when the system enters into WOW suspend in STA mode.
+ Unicast packet pattern
+ mDNS/SSDP/LLMNR pattern
* Move the user provided WOW patterns configuration code
from ath6kl_wow_suspend() to a separate function called
ath6kl_wow_usr().
* Two argument variable's ('filter' and 'mask) data type in
ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
'const u8 *'. This is needed to make all pattern and mask
arrays to be 'static const u8' in the caller function.
* New conditional check is added to make sure user
configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.
If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.
Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.
New module parameter suspend_mode can take any one of
the below suspend state,
1. cut power
2. deep sleep

When an interrupt comes in, we read the reason
bits and collect them into "trans_pcie->inta".
This happens with the spinlock held. However,
there's a bug resetting this variable -- that
happens after the spinlock has been released.
This means that it is possible for interrupts
to be missed if the reset happens after some
other interrupt reasons were already added to
the variable.
I found this by code inspection, looking for a
reason that we sometimes see random commands
time out. It seems possible that this causes
such behaviour, but I can't say for sure right
now since it happens extremely infrequently on
my test systems.

Two fixes for regressions introduced during the merge window, one fix for
a long-standing obscure issue in the computation of hibernate image size
and two small PM documentation fixes.
* tag 'pm-fixes-for-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM / Sleep: Fix read_unlock_usermodehelper() call.
PM / Hibernate: Rewrite unlock_system_sleep() to fix s2disk regression
PM / Hibernate: Correct additional pages number calculation
PM / Documentation: Fix minor issue in freezing_of_tasks.txt
PM / Documentation: Fix spelling mistake in basic-pm-debugging.txt
Commit b298d289
"PM / Sleep: Fix freezer failures due to racy usermodehelper_is_disabled()"
added read_unlock_usermodehelper() but read_unlock_usermodehelper() is called
without read_lock_usermodehelper() when kmalloc() failed.

tg3_start_xmit() makes the wrong assumption for TSOV6 that skb->head
doesnt include any payload data.
if (skb_is_gso_v6(skb))
hdr_len = skb_headlen(skb) - ETH_HLEN;
This is not true anymore after commit f07d960df3 (tcp: avoid frag
allocation for small frames)
We should instead use : skb_transport_offset(skb) + tcp_hdrlen(skb)
Its also true for IPv4

Upon insertion of elements into the execution queue, it is validated
that there are enough credits to support additional vlan-macs,
and the credits are consumed. However, when removing a pending
command in `bnx2x_vland_mac_del_all' the consumed credits are not
released, which might cause leakage and eventually the inability to

RSS rings can be created on one (out of four) interfaces per port in a
multi-channel config. Doing this insulates the driver from a FW bug wherin
multi-channel config is wrongly reported even when not enabled. This also
helps performance in a multi-channel config, as one interface per port gets
RSS rings.

bond_alb_init_slave() is called from bond_enslave() and sets the slave's MAC
address. This is done differently for TLB and ALB modes.
bond->alb_info.rlb_enabled is used to discriminate between the two modes but
this flag may be uninitialized if the slave is being enslaved prior to calling
bond_open() -> bond_alb_initialize() on the master.
It turns out all the callers of alb_set_slave_mac_addr() pass
bond->alb_info.rlb_enabled as the hw parameter.
This patch cleans up the unnecessary parameter of alb_set_slave_mac_addr() and
makes the function decide based on the bonding mode instead, which fixes the
above problem.

This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e6713f ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.
The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver... Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.

Tested on two platforms, one with a valid MAC, the other without a MAC. The real
MAC is used if present, the interface fails to come up until the MAC is set on
the other. They successfully get an IP over DHCP and pass a simple ping and
login over ssh test.
This is meant to allow the Inforce SYS940X development board:
http://www.inforcecomputing.com/SYS940X_ECX.html
(and others suffering from a missing MAC) to work with the mainline kernel.
Without this patch, the probe will fail and the interface will not be created,
preventing the user from configuring the MAC manually.
This does not make any attempt to address a missing or invalid MAC for the

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.
Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.

If the frontend is in idle state, don't call get_frontend.
Calling get_frontend() when the device is not tuned may
result in wrong parameters to be returned to the
userspace.
I was tempted to not call get_frontend() at all, except
inside the dvb frontend thread, but this won't work for
all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB
STD-B31) allow the broadcaster to dynamically change the
channel specs at runtime. That means that an ISDB-T optimized
application may want/need to monitor the TMCC tables, decoded
at the frontends via get_frontend call.
So, let's do the simpler change here.
Eventually, the logic could be changed to work only if
the device is tuned and has lock, but, even so, the
lock is also standard-dependent. For ISDB-T, the right
lock to wait is that the demod has TMCC lock. So, drivers
may need to implement some logic to detect if the get_frontend
info was retrieved or not.

The Super-Isolate mode comes to isolate the BCM84833 PHY from the
outside world. Not doing it correctly, made link partner see the link
before the driver was loaded.
This patch also involves SPIROM version fixes since it is used to
determine whether the common init of the PHY was already executed, and
the common init of this PHY is partially responsible for setting the
Super-Isolate mode.

For UP processor, it is likely that no _MAT method or MADT table defined.
So currently acpi_get_cpuid(...) always return -1 for UP processor.
This is wrong. It should return valid value for CPU0.
In the other hand, BIOS may define multiple CPU handles even for UP
processor, for example
Scope (_PR)
{
Processor (CPU0, 0x00, 0x00000410, 0x06) {}
Processor (CPU1, 0x01, 0x00000410, 0x06) {}
Processor (CPU2, 0x02, 0x00000410, 0x06) {}
Processor (CPU3, 0x03, 0x00000410, 0x06) {}
}
We should only return valid value for CPU0's acpi handle.
And return invalid value for others.

smp_call_function() only lets all other CPUs execute a specific function,
while we expect all CPUs do in intel_idle. Without the fix, we could have
one cpu which has auto_demotion enabled or has no broadcast timer setup.
Usually we don't see impact because auto demotion just harms power and the
intel_idle init is called in CPU 0, where boradcast timer delivers
interrupt, but this still could be a problem.

APEI needs memory access in interrupt context. The obvious choice is
acpi_read(), but originally it couldn't be used in interrupt context
because it makes temporary mappings with ioremap(). Therefore, we added
drivers/acpi/atomicio.c, which provides:
acpi_pre_map_gar() -- ioremap in process context
acpi_atomic_read() -- memory access in interrupt context
acpi_post_unmap_gar() -- iounmap
Later we added acpi_os_map_generic_address() (2971852) and enhanced
acpi_read() so it works in interrupt context as long as the address has
been previously mapped (620242a). Now this sequence:
acpi_os_map_generic_address() -- ioremap in process context
acpi_read()/apei_read() -- now OK in interrupt context
acpi_os_unmap_generic_address()
is equivalent to what atomicio.c provides.
This patch introduces apei_read() and apei_write(), which currently are
functional equivalents of acpi_read() and acpi_write(). This is mainly
proactive, to prevent APEI breakages if acpi_read() and acpi_write()
are ever augmented to support the 'bit_offset' field of GAS, as APEI's
__apei_exec_write_register() precludes splitting up functionality
related to 'bit_offset' and APEI's 'mask' (see its
APEI_EXEC_PRESERVE_REGISTER block).
With apei_read() and apei_write() in place, usages of atomicio routines
are converted to apei_read()/apei_write() and existing calls within
osl.c and the CA, based on the re-factoring that was done in an earlier
patch series - http://marc.info/?l=linux-acpi&m=128769263327206&w=2:
acpi_pre_map_gar() --> acpi_os_map_generic_address()
acpi_post_unmap_gar() --> acpi_os_unmap_generic_address()
acpi_atomic_read() --> apei_read()
acpi_atomic_write() --> apei_write()
Note that acpi_read() and acpi_write() currently use 'bit_width'
for accessing GARs which seems incorrect. 'bit_width' is the size of
the register, while 'access_width' is the size of the access the
processor must generate on the bus. The 'access_width' may be larger,
for example, if the hardware only supports 32-bit or 64-bit reads. I
wanted to minimize any possible impacts with this patch series so I
did *not* change this behavior.

Export remapping and unmapping interfaces - acpi_os_map_generic_address()
and acpi_os_unmap_generic_address() - for ACPI generic registers that are
backed by memory mapped I/O (MMIO).
The acpi_os_map_generic_address() and acpi_os_unmap_generic_address()
declarations may more properly belong in include/acpi/acpiosxf.h next to
acpi_os_read_memory() but I believe that would require the ACPI CA making
them an official part of the ACPI CA - OS interface.

Some firmware will access memory in ACPI NVS region via APEI. That
is, instructions in APEI ERST/EINJ table will read/write ACPI NVS
region. The original resource conflict checking in APEI code will
check memory/ioport accessed by APEI via general resource management
mech. But ACPI NVS region is marked as busy already, so that the
false resource conflict will prevent APEI ERST/EINJ to work.
To fix this, this patch excludes ACPI NVS regions when APEI components
request resources. So that they will not conflict with ACPI NVS

Some APEI firmware implementation will access injected address
specified in param1 to trigger the error when injecting memory error.
This will cause resource conflict with RAM.
On one of our testing machine, if injecting at memory address
0x10000000, the following error will be reported in dmesg:
APEI: Can not request iomem region <0000000010000000-0000000010000008> for GARs.

# echo 0xfffffffffffff000 > param2
# echo 0x8 > error_type
# echo 1 > error_inject

echo: write error: Input/output error
The EIO comes from:
rc = apei_exec_pre_map_gars(&trigger_ctx);
The root cause is as follow. Normally, ACPI atomic IO support is used
to access IO memory. But in EINJ of that machine, it is used to
access RAM to trigger the injected error. And the ioremap() called by
apei_exec_pre_map_gars() can not map the RAM.
This patch add RAM mapping support to ACPI atomic IO support to
satisfy EINJ requirement.

In most cases, printk only guarantees messages from different printk
calling will not be interleaved between each other. But, one APEI
GHES hardware error report will involve multiple printk calling,
normally each for one line. So it is possible that the hardware error
report comes from different generic hardware error source will be
interleaved.
In this patch, a sequence number is prefixed to each line of error
report. So that, even if they are interleaved, they still can be
distinguished by the prefixed sequence number.
