2009-11-10swiotlb: Add swiotlb_free() functionFUJITA Tomonori
swiotlb_free() function frees all allocated memory for swiotlb. We need to initialize swiotlb before IOMMU initialization (x86 and powerpc needs to allocate memory from bootmem allocator). If IOMMU initialization is successful, we need to free swiotlb resource (don't want to waste 64MB).

2009-11-10bootmem: Add free_bootmem_late()FUJITA Tomonori
Add a new function for freeing bootmem after the bootmem allocator has been released and the unreserved pages given to the page allocator. This allows us to reserve bootmem and then release it if we later discover it was not needed. ( This new API will be used by the swiotlb code to recover a significant amount of RAM (64MB). ) Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Cc: chrisw@sous-sol.org Cc: dwmw2@infradead.org Cc: joerg.roedel@amd.com Cc: muli@il.ibm.com Cc: hannes@cmpxchg.org Cc: tj@kernel.org Cc: akpm@linux-foundation.org Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <1257849980-22640-7-git-send-email-fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-11-10x86: Add iommu_init to x86_init_opsFUJITA Tomonori
We call the detections functions of all the IOMMUs then all their initialization functions. The latter is pointless since we don't detect multiple different IOMMUs. What we need to do is calling the initialization function of the detected IOMMU. This adds iommu_init hook to x86_init_ops so if an IOMMU detection function can set its initialization function to the hook.

2009-11-10x86: Under BIOS control, restore AP's APIC_LVTTHMR to the BSP valueYong Wang
On platforms where the BIOS handles the thermal monitor interrupt, APIC_LVTTHMR on each logical CPU is programmed to generate a SMI and OS must not touch it. Unfortunately AP bringup sequence using INIT-SIPI-SIPI clears all the LVT entries except the mask bit. Essentially this results in all LVT entries including the thermal monitoring interrupt set to masked (clearing the bios programmed value for APIC_LVTTHMR). And this leads to kernel take over the thermal monitoring interrupt on AP's but not on BSP (leaving the bios programmed value only on BSP). As a result of this, we have seen system hangs when the thermal monitoring interrupt is generated. Fix this by reading the initial value of thermal LVT entry on BSP and if bios has taken over the control, then program the same value on all AP's and leave the thermal monitoring interrupt control on all the logical cpu's to the bios.

2009-11-10rcu: Fix note_new_gpnum() uses of ->gpnumPaul E. McKenney
Impose a clear locking design on the note_new_gpnum() function's use of the ->gpnum counter. This is done by updating rdp->gpnum only from the corresponding leaf rcu_node structure's rnp->gpnum field, and even then only under the protection of that same rcu_node structure's ->lock field. Performance and scalability are maintained using a form of double-checked locking, and excessive spinning is avoided by use of the spin_trylock() function. The use of spin_trylock() is safe due to the fact that CPUs who fail to acquire this lock will try again later. The hierarchical nature of the rcu_node data structure limits contention (which could be limited further if need be using the RCU_FANOUT kernel parameter). Without this patch, obscure but quite possible races could result in a quiescent state that occurred during one grace period to be accounted to the following grace period, causing this following grace period to end prematurely.

2009-11-10rcu: Fix synchronization for rcu_process_gp_end() uses of ->completed counterPaul E. McKenney
Impose a clear locking design on the rcu_process_gp_end() function's use of the ->completed counter. This is done by creating a ->completed field in the rcu_node structure, which can safely be accessed under the protection of that structure's lock. Performance and scalability are maintained by using a form of double-checked locking, so that rcu_process_gp_end() only acquires the leaf rcu_node structure's ->lock if a grace period has recently ended. This fix reduces rcutorture failure rate by at least two orders of magnitude under heavy stress with force_quiescent_state() being invoked artificially often. Without this fix, unsynchronized access to the ->completed field can cause rcu_process_gp_end() to advance callbacks whose grace period has not yet expired. (Bad idea!) Signed-off-by: Paul E.

Chris Wright has some patches which let us fall back to swiotlb nicely if IOMMU initialisation fails. But those are a bit much for 2.6.32. Instead, let's shift the check for the biggest problem, the HP and Acer BIOS bug which reports a DMAR at physical address zero. That one can actually be checked much earlier -- before we even admit to having detected an IOMMU in the first place. So the swiotlb init goes ahead as we want.

2009-11-09ksm: cond_resched in unstable treeHugh Dickins
