2010-03-09Blackfin: SMP: make core timers per-cpu clock events for HRTYi Li
SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer.

2010-03-09Blackfin: MPU: handle caches for reserved memorySonic Zhang

2010-03-09Blackfin: fix MPU page permission masks overflow when dealing with async memoryBarry Song
Attempting to use the MPU while doing XIP out of parallel flash hooked up to the async memory bus would often result in random crashes as the MPU slowly corrupted memory. The fallout here is that the async banks gain MPU protection from user space too. So any accesses have to go through the mmap() interface rather than just using hardcoded pointers.

2010-03-09Blackfin: flush caches on SMP when one core calls another via IPIYi Li

2010-03-09powerpc/booke: Fix breakpoint/watchpoint one-shot behaviorDave Kleikamp
Another fix for the extended ptrace patches in the -next tree. The handling of breakpoints and watchpoints is inconsistent. When a breakpoint or watchpoint is hit, the interrupt handler is clearing the proper bits in the dbcr* registers, but leaving the dac* and iac* registers alone. The ptrace code to delete the break/watchpoints checks the dac* and iac* registers for zero to determine if they are enabled. Instead, they should check the dbcr* bits.

2010-03-09powerpc: Reset kernel stack on cpu online from cede stateVaidyanathan Srinivasan
Cpu hotplug (offline) without dlpar operation will place cpu in cede state and the extended_cede_processor() function will return when resumed. Kernel stack pointer needs to be reset before start_secondary() is called to continue the online operation. Added new function start_secondary_resume() to do the above steps.

2010-03-09powerpc/pseries: Pass CPPR value to H_XIRR hcallMark Nelson
Now that we properly keep track of the CPPR value (since 49bd3647134ea47420067aea8d1401e722bf2aac, "powerpc/pseries: Track previous CPPR values to correctly EOI interrupts") we can pass it to the H_XIRR hcall. This is needed because the Partition Adjunct Option of new versions of pHyp extend the H_XIRR hcall to include the CPPR as an input parameter. Earlier versions not supporting this option just disregard the extra input parameter, so this doesn't cause any problems for existing systems. The Partition Adjunct Option is required for future systems that will support SR-IOV capable devices.

2010-03-09powerpc: Dynamically allocate pacasMichael Ellerman
On 64-bit kernels we currently have a 512 byte struct paca_struct for each cpu (usually just called "the paca"). Currently they are statically allocated, which means a kernel built for a large number of cpus will waste a lot of space if it's booted on a machine with few cpus. We can avoid that by only allocating the number of pacas we need at boot. However this is complicated by the fact that we need to access the paca before we know how many cpus there are in the system. The solution is to dynamically allocate enough space for NR_CPUS pacas, but then later in boot when we know how many cpus we have, we free any unused pacas.

2010-03-08Btrfs: use RB_ROOT to intialize rb_trees instead of setting rb_node to NULLEric Paris
btrfs inialize rb trees in quite a number of places by settin rb_node = NULL; The problem with this is that 17d9ddc72fb8bba0d4f678 in the linux-next tree adds a new field to that struct which needs to be NULL for the new rbtree library code to work properly. This patch uses RB_ROOT as the intializer so all of the relevant fields will be NULL'd. Without the patch I get a panic.

2010-03-08tipc: filter out messages not intended for this hostNeil Horman
Port commit 20deb48d16fdd07ce2fdc8d03ea317362217e085 from git://tipc.cslab.ericsson.net/pub/git/people/allan/tipc.git Part of the large effort I'm trying to help with getting all the downstreamed code from windriver forward ported to the upstream tree Origional commit message Restore check to filter out inadverdently received messages This patch reimplements a check that allows TIPC to discard messages that are not intended for it. This check was present in TIPC 1.5/1.6, but was removed by accident during the development of TIPC 1.7; it has now been updated to account for new features present in TIPC 1.7 and reinserted into TIPC. The main benefit of this check is to filter out messages arriving from orphaned link endpoints, which can arise when a node exits the network and then re-enters it with a different TIPC network address (i.e. <Z.C.N> value).
