2012-01-06PCI: Pull PCI 'latency timer' setup up into the coreMyron Stowe
The 'latency timer' of PCI devices, both Type 0 and Type 1, is setup in architecture-specific code [see: 'pcibios_set_master()']. There are two approaches being taken by all the architectures - check if the 'latency timer' is currently set between 16 and 255 and if not bring it within bounds, or, do nothing (and then there is the gratuitously different PA-RISC implementation). There is nothing architecture-specific about PCI's 'latency timer' so this patch pulls its setup functionality up into the PCI core by creating a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over-ridden by architecture-specific code. No functional change. Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2011-12-27net: meth: Add set_rx_mode hook to fix ICMPv6 neighbor discoveryJoshua Kinard
SGI IP32 (O2)'s ethernet driver (meth) lacks a set_rx_mode function, which prevents IPv6 from working completely because any ICMPv6 neighbor solicitation requests aren't picked up by the driver. So the machine can ping out and connect to other systems, but other systems will have a very hard time connecting to the O2. Signed-off-by: Joshua Kinard <kumba@gentoo.org> Signed-off-by: David S.

2011-12-11nohz: Remove tick_nohz_idle_enter_norcu() / tick_nohz_idle_exit_norcu()Frederic Weisbecker
Those two APIs were provided to optimize the calls of tick_nohz_idle_enter() and rcu_idle_enter() into a single irq disabled section. This way no interrupt happening in-between would needlessly process any RCU job. Now we are talking about an optimization for which benefits have yet to be measured. Let's start simple and completely decouple idle rcu and dyntick idle logics to simplify.

2011-12-11nohz: Allow rcu extended quiescent state handling seperately from tick stopFrederic Weisbecker
It is assumed that rcu won't be used once we switch to tickless mode and until we restart the tick. However this is not always true, as in x86-64 where we dereference the idle notifiers after the tick is stopped. To prepare for fixing this, add two new APIs: tick_nohz_idle_enter_norcu() and tick_nohz_idle_exit_norcu(). If no use of RCU is made in the idle loop between tick_nohz_enter_idle() and tick_nohz_exit_idle() calls, the arch must instead call the new *_norcu() version such that the arch doesn't need to call rcu_idle_enter() and rcu_idle_exit(). Otherwise the arch must call tick_nohz_enter_idle() and tick_nohz_exit_idle() and also call explicitly: - rcu_idle_enter() after its last use of RCU before the CPU is put to sleep. - rcu_idle_exit() before the first use of RCU after the CPU is woken up.

2011-12-11nohz: Separate out irq exit and idle loop dyntick logicFrederic Weisbecker
The tick_nohz_stop_sched_tick() function, which tries to delay the next timer tick as long as possible, can be called from two places: - From the idle loop to start the dytick idle mode - From interrupt exit if we have interrupted the dyntick idle mode, so that we reprogram the next tick event in case the irq changed some internal state that requires this action. There are only few minor differences between both that are handled by that function, driven by the ts->inidle cpu variable and the inidle parameter. The whole guarantees that we only update the dyntick mode on irq exit if we actually interrupted the dyntick idle mode, and that we enter in RCU extended quiescent state from idle loop entry only. Split this function into: - tick_nohz_idle_enter(), which sets ts->inidle to 1, enters dynticks idle mode unconditionally if it can, and enters into RCU extended quiescent state. - tick_nohz_irq_exit() which only updates the dynticks idle mode when ts->inidle is set (ie: if tick_nohz_idle_enter() has been called). To maintain symmetry, tick_nohz_restart_sched_tick() has been renamed into tick_nohz_idle_exit(). This simplifies the code and micro-optimize the irq exit path (no need for local_irq_save there). This also prepares for the split between dynticks and rcu extended quiescent state logics. We'll need this split to further fix illegal uses of RCU in extended quiescent states in the idle loop.

2011-12-08memblock: Kill early_node_map[]Tejun Heo
Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP - there's no user of early_node_map[] left. Kill early_node_map[] and replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP. Also, relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h as page_alloc.c would no longer host an alternative implementation. This change is ultimately one to one mapping and shouldn't cause any observable difference; however, after the recent changes, there are some functions which now would fit memblock.c better than page_alloc.c and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK doesn't make much sense on some of them. Further cleanups for functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice. -v2: Fix compile bug introduced by mis-spelling CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in mmzone.h.

2011-12-08net/irda: convert au1k_ir to platform driver.Manuel Lauss
Moderate driver cleanup: convert to platform driver, get rid of board-specific code. Driver loads and runs on a DB1100 board. But since I have no other IrDA hardware to exchange data with I can't say whether it really sends and receives.

2011-12-07MIPS: Netlogic: Mark Netlogic chips as SMT capableHillf Danton
Netlogic XLR chip has multiple cores. Each core includes four integrated hardware threads, and they share L1 data and instruction caches. If the chip is marked to be SMT capable, scheduler then could do more, say, idle load balancing. Changes are now confined only to the code of XLR, and hardware is probed to get core ID for correct setup.

2011-12-07MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C
Create a common NMI and reset handler in smpboot.S and use this for both XLR and XLP. In the earlier code, the woken up CPUs would busy wait until released, switch this to wakeup by NMI. The initial wakeup code or XLR and XLP are differ since they are started from different bootloaders (XLP from u-boot and XLR from netlogic bootloader). But in both platforms the woken up CPUs wait and are released by sending an NMI. Add support for starting XLR and XLP in 1/2/4 threads per core.
