2011-01-18sched, autogroup: Fix CONFIG_RT_GROUP_SCHED sched_setscheduler() failureMike Galbraith
If CONFIG_RT_GROUP_SCHED is set, __sched_setscheduler() fails due to autogroup not allocating rt_runtime. Free unused/unusable rt_se and rt_rq, redirect RT tasks to the root task group, and tell __sched_setscheduler() that it's ok.

2011-01-18sched: Update effective_load() to use global share weightsPaul Turner
Previously effective_load would approximate the global load weight present on a group taking advantage of: entity_weight = tg->shares ( lw / global_lw ), where entity_weight was provided by tg_shares_up. This worked (approximately) for an 'empty' (at tg level) cpu since we would place boost load representative of what a newly woken task would receive. However, now that load is instantaneously updated this assumption is no longer true and the load calculation is rather incorrect in this case. Fix this (and improve the general case) by re-writing effective_load to take advantage of the new shares distribution code.

2011-01-18x86: Make relocatable kernel work with new binutilsShaohua Li
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make boot panic. According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to 2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is using such binutils. See: http://sourceware.org/bugzilla/show_bug.cgi?id=12327 The reason of the boot panic is that we have 'jiffies = jiffies_64;' in vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is warning saying jiffies is an absolute address and can't be relocatable. At runtime, jiffies will have virtual address 0.

2011-01-18autofs4 - fix get_next_positive_dentry()Ian Kent
The initialization condition in fs/autofs4/expire.c:get_next_positive_dentry() appears to be incorrect. If prev == NULL I believe that root should be returned. Further down, at the current dentry check for it being simple_positive() it looks like the d_lock for dentry p should be dropped instead of dentry ret, otherwise when p is assinged to ret we end up with no lock on p and a lost lock on ret, which leads to a deadlock.

2011-01-17ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan
The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).
