2014-10-23intel_pstate: Correct BYT VID values.Dirk Brandewie
Using a VID value that is not high enough for the requested P state can cause machine checks. Add a ceiling function to ensure calulated VIDs with fractional values are set to the next highest integer VID value. The algorythm for calculating the non-trubo VID from the BIOS writers guide is: vid_ratio = (vid_max - vid_min) / (max_pstate - min_pstate) vid = ceiling(vid_min + (req_pstate - min_pstate) * vid_ratio) Cc: All applicable <stable@vger.kernel.org> Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com> Signed-off-by: Rafael J.

2014-10-23cpufreq: intel_pstate: Fix setting max_perf_pct in performance policyPali Rohár
Code which changes policy to powersave changes also max_policy_pct based on max_freq. Code which change max_perf_pct has upper limit base on value max_policy_pct. When policy is changing from powersave back to performance then max_policy_pct is not changed. Which means that changing max_perf_pct is not possible to high values if max_freq was too low in powersave policy. Test case: $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 800000 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 3300000 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor performance $ cat /sys/devices/system/cpu/intel_pstate/max_perf_pct 100 $ echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor $ echo 800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq $ echo 20 > /sys/devices/system/cpu/intel_pstate/max_perf_pct $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor powersave $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 800000 $ cat /sys/devices/system/cpu/intel_pstate/max_perf_pct 20 $ echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor $ echo 3300000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq $ echo 100 > /sys/devices/system/cpu/intel_pstate/max_perf_pct $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor performance $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 3300000 $ cat /sys/devices/system/cpu/intel_pstate/max_perf_pct 24 And now intel_pstate driver allows to set maximal value for max_perf_pct based on max_policy_pct which is 24 for previous powersave max_freq 800000. This patch will set default value for max_policy_pct when setting policy to performance so it will allow to set also max value for max_perf_pct.

2014-10-23iwlwifi: dvm: drop non VO frames when flushingEmmanuel Grumbach
When mac80211 wants to ensure that a frame is sent, it calls the flush() callback. Until now, iwldvm implemented this by waiting that all the frames are sent (ACKed or timeout). In case of weak signal, this can take a significant amount of time, delaying the next connection (in case of roaming). Many users have reported that the flush would take too long leading to the following error messages to be printed: iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201 iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00 [snip] iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000 [snip] iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9] [snip] Instead of waiting for these packets, simply drop them. This significantly improves the responsiveness of the network. Note that all the queues are flushed, but the VO one. This is not typically used by the applications and it likely contains management frames that are useful for connection or roaming. This bug is tracked here: https://bugzilla.kernel.org/show_bug.cgi?id=56581 But it is duplicated in distributions' trackers.

2014-10-23ath: use CTL region from cfg80211 if unset in EEPROMFelix Fietkau
Many AP devices do not have the proper regulatory domain programmed in EEPROM. Instead they expect the software to set the appropriate region. For these devices, the country code defaults to US, and the driver uses the US CTL tables as well. On devices bought in Europe this can lead to tx power being set too high on the band edges, even if the cfg80211 regdomain is set correctly. Fix this issue by taking into account the DFS region, but only when the EEPROM regdomain is set to default. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2014-10-23bcma: fix build when CONFIG_OF_ADDRESS is not setHauke Mehrtens
Commit 2101e533f41a ("bcma: register bcma as device tree driver") introduces a hard dependency on OF_ADDRESS into the bcma driver. OF_ADDRESS is specifically disabled for the sparc architecture. This results in the following error when building sparc64:allmodconfig. drivers/bcma/main.c: In function 'bcma_of_find_child_device': drivers/bcma/main.c:150:3: error: implicit declaration of function 'of_translate_address' Fixes: 2101e533f41a ("bcma: register bcma as device tree driver") Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: John W.

2014-10-23nfsd4: fix crash on unknown operation numberJ. Bruce Fields
Unknown operation numbers are caught in nfsd4_decode_compound() which sets op->opnum to OP_ILLEGAL and op->status to nfserr_op_illegal. The error causes the main loop in nfsd4_proc_compound() to skip most processing. But nfsd4_proc_compound also peeks ahead at the next operation in one case and doesn't take similar precautions there.

2014-10-23MIPS: idle: Remove leftover __pastwait symbol and its referencesMarkos Chandras
The __pastwait symbol was only used by the address_is_in_r4k_wait_irqoff function but this is no longer used since the SMTC removal in commit b633648c5ad3 ('MIPS: MT: Remove SMTC support'). That symbol also led to build failures under certain random configuration due to the way the compiler compiled the r4k_wait_irqoff function. If that function was called multiple times, the __pastwait symbol was redefined breaking the build like this: CHK include/generated/compile.h CC arch/mips/kernel/idle.o {standard input}: Assembler messages: {standard input}:527: Error: symbol `__pastwait' is already defined Link: http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1244879922.24479.30.camel%40falcon Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Markos Chandras <markos.chandras@imgtec.com> Patchwork: https://patchwork.linux-mips.org/patch/7791/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
