2011-07-14tg3: Determine PCI function number in one placeMatt Carlson
tg3 devices will need to know exactly what function number they are so that they can communicate their status to the other functions. In a KVM environment, the function number of a device presented by the kernel might not be the true function number, so an alternative method to determine the function number is needed. This patch used to contain an implementation for the alternative method, but recently we discovered a hardware bug that renders it incorrect. While new method is not yet known, it is still useful to consolidate the code that determines the PCI function to one location and use the results throughout the code.

2011-07-14tg3: Check transitions to D0 power stateMatt Carlson
Currently pci_set_power_state() does not return useful return codes for transitions to the D0 power state. If a device refuses to go into D0, the PCI layer issues a warning but returns success. Entering into D0 is a requirement for correct operation of tg3 devices though. If the PCI layer should be changed to return an error code for this type of failure, the tg3 driver would be interested in catching it and reacting to it. This patch makes the necessary modifications. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-07-14sched: adjust scheduler cpu power for stolen timeGlauber Costa
This patch makes update_rq_clock() aware of steal time. The mechanism of operation is not different from irq_time, and follows the same principles. This lives in a CONFIG option itself, and can be compiled out independently of the rest of steal time reporting. The effect of disabling it is that the scheduler will still report steal time (that cannot be disabled), but won't use this information for cpu power adjustments. Everytime update_rq_clock_task() is invoked, we query information about how much time was stolen since last call, and feed it into sched_rt_avg_update(). Although steal time reporting in account_process_tick() keeps track of the last time we read the steal clock, in prev_steal_time, this patch do it independently using another field, prev_steal_time_rq. This is because otherwise, information about time accounted in update_process_tick() would never reach us in update_rq_clock().

2011-07-14KVM guest: Steal time accountingGlauber Costa
This patch accounts steal time time in account_process_tick. If one or more tick is considered stolen in the current accounting cycle, user/system accounting is skipped. Idle is fine, since the hypervisor does not report steal time if the guest is halted. Accounting steal time from the core scheduler give us the advantage of direct acess to the runqueue data. In a later opportunity, it can be used to tweak cpu power and make the scheduler aware of the time it lost.

2011-07-14KVM: Steal time implementationGlauber Costa
To implement steal time, we need the hypervisor to pass the guest information about how much time was spent running other processes outside the VM, while the vcpu had meaningful work to do - halt time does not count. This information is acquired through the run_delay field of delayacct/schedstats infrastructure, that counts time spent in a runqueue but not running. Steal time is a per-cpu information, so the traditional MSR-based infrastructure is used. A new msr, KVM_MSR_STEAL_TIME, holds the memory area address containing information about steal time This patch contains the hypervisor part of the steal time infrasructure, and can be backported independently of the guest portion.

2011-07-14GFS2: Resolve inode eviction and ail list interaction bugSteven Whitehouse
This patch contains a few misc fixes which resolve a recently reported issue. This patch has been a real team effort and has received a lot of testing. The first issue is that the ail lock needs to be held over a few more operations. The lock thats added into gfs2_releasepage() may possibly be a candidate for replacing with RCU at some future point, but at this stage we've gone for the obvious fix. The second issue is that gfs2_write_inode() can end up calling a glock recursively when called from gfs2_evict_inode() via the syncing code, so it needs a guard added. The third issue is that we either need to not truncate the metadata pages of inodes which have zero link count, but which we cannot deallocate due to them still being in use by other nodes, or we need to ensure that those pages have all made it through the journal and ail lists first. This patch takes the former approach, but the latter has also been tested and there is nothing to choose between them performance-wise. So again, we could revise that decision in the future. Also, the inode eviction process is now better documented.

2011-07-13ftrace: Fix dynamic selftest failure on some archsSteven Rostedt
Archs that do not implement CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST, will fail the dynamic ftrace selftest. The function tracer has a quick 'off' variable that will prevent the call back functions from being called. This variable is called function_trace_stop. In x86, this is implemented directly in the mcount assembly, but for other archs, an intermediate function is used called ftrace_test_stop_func(). In dynamic ftrace, the function pointer variable ftrace_trace_function is used to update the caller code in the mcount caller. But for archs that do not have CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST set, it only calls ftrace_test_stop_func() instead, which in turn calls __ftrace_trace_function. When more than one ftrace_ops is registered, the function it calls is ftrace_ops_list_func(), which will iterate over all registered ftrace_ops and call the callbacks that have their hash matching. The issue happens when two ftrace_ops are registered for different functions and one is then unregistered. The __ftrace_trace_function is then pointed to the remaining ftrace_ops callback function directly. This mean it will be called for all functions that were registered to trace by both ftrace_ops that were registered. This is not an issue for archs with CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST, because the update of ftrace_trace_function doesn't happen until after all functions have been updated, and then the mcount caller is updated. But for those archs that do use the ftrace_test_stop_func(), the update is immediate. The dynamic selftest fails because it hits this situation, and the ftrace_ops that it registers fails to only trace what it was suppose to and instead traces all other functions. The solution is to delay the setting of __ftrace_trace_function until after all the functions have been updated according to the registered ftrace_ops. Also, function_trace_stop is set during the update to prevent function tracing from calling code that is caused by the function tracer itself. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-07-13ftrace: Update filter when tracing enabled in set_ftrace_filter()Steven Rostedt
Currently, if set_ftrace_filter() is called when the ftrace_ops is active, the function filters will not be updated. They will only be updated when tracing is disabled and re-enabled. Update the functions immediately during set_ftrace_filter(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-07-13ftrace: Balance records when updating the hashSteven Rostedt
Whenever the hash of the ftrace_ops is updated, the record counts must be balance. This requires disabling the records that are set in the original hash, and then enabling the records that are set in the updated hash. Moving the update into ftrace_hash_move() removes the bug where the hash was updated but the records were not, which results in ftrace triggering a warning and disabling itself because the ftrace_ops filter is updated while the ftrace_ops was registered, and then the failure happens when the ftrace_ops is unregistered. The current code will not trigger this bug, but new code will. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2011-07-13[media] dvb_frontend: fix race condition in stopping/starting frontendDevin Heitmueller
Attached is a patch which addresses a race condition in the DVB core related to closing/reopening the DVB frontend device in quick succession. This is the reason that devices such as the HVR-1300, HVR-3000, and HVR-4000 have been failing to scan properly under MythTV and w_scan. The gory details of the race are described in the patch. Devin There is a race condition exhibited when channel scanners such as w_scan and MythTV quickly close and then reopen the frontend device node. Under normal conditions, the behavior is as follows: 1. Application closes the device node 2. DVB frontend ioctl calls dvb_frontend_release which sets fepriv->release_jiffies 3. DVB frontend thread *eventually* calls dvb_frontend_is_exiting() which compares fepriv->release_jiffies, and shuts down the thread if timeout has expired 4. Thread goes away 5. Application opens frontend device 6. DVB frontend ioctl() calls ts_bus_ctrl(1) 7. DVB frontend ioctl() creates new frontend thread, which calls dvb_frontend_init(), which has demod driver init() routine setup initial register state for demod chip. 8. Tuning request is issued. The race occurs when the application in step 5 performs the new open() call before the frontend thread is shutdown. In this case the ts_bus_ctrl() call is made, which strobes the RESET pin on the demodulator, but the dvb_frontend_init() function never gets called because the frontend thread hasn't gone away yet. As a result, the initial register config for the demod is *never* setup, causing subsequent tuning requests to fail. If there is time between the close and open (enough for the dvb frontend thread to be torn down), then in that case the new frontend thread is created and thus the dvb_frontend_init() function does get called. The fix is to set the flag which forces reinitialization if we did in fact call ts_bus_ctrl(). This problem has been seen on the HVR-1300, HVR-3000, and HVR-4000, and is likely occuring on other designs as well where ts_bus_ctrl() actually strobes the reset pin on the demodulator. Note that this patch should supercede any patches submitted for the 1300/3000/4000 which remove the code that removes GPIO code in cx8802_dvb_advise_acquire(), which have been circulating by users for some time now...

This fixes a regression introduced in 3.0-rc1 by 08ee80cc397ac1a3 ("mmc: core: eMMC bus width may not work on all platforms"), which incorrectly assumed we would be re-reading the ext_csd at resume- time.

2011-07-13mac80211: allow driver to disconnect after resumeJohannes Berg
In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.
