2008-06-12pagemap: pass mm into pagewalkersDave Hansen
We need this at least for huge page detection for now, because powerpc needs the vm_area_struct to be able to determine whether a virtual address is referring to a huge page (its pmd_huge() doesn't work). It might also come in handy for some of the other users.

2008-06-12common implementation of iterative div/modJeremy Fitzhardinge
We have a few instances of the open-coded iterative div/mod loop, used when we don't expcet the dividend to be much bigger than the divisor. Unfortunately modern gcc's have the tendency to strength "reduce" this into a full mod operation, which isn't necessarily any faster, and even if it were, doesn't exist if gcc implements it in libgcc. The workaround is to put a dummy asm statement in the loop to prevent gcc from performing the transformation. This patch creates a single implementation of this loop, and uses it to replace the open-coded versions I know about.

2008-06-11cpuidle acpi driver: fix oops on AC<->DCVenkatesh Pallipadi
cpuidle and acpi driver interaction bug with the way cpuidle_register_driver() is called. Due to this bug, there will be oops on AC<->DC on some systems, where they support C-states in one DC and not in AC. The current code does ON BOOT: Look at CST and other C-state info to see whether more than C1 is supported. If it is, then acpi processor_idle does a cpuidle_register_driver() call, which internally enables the device. ON CST change notification (AC<->DC) and on suspend-resume: acpi driver temporarily disables device, updates the device with any new C-states, and reenables the device. The problem is is on boot, there are no C2, C3 states supported and we skip the register. Later on AC<->DC, we may get a CST notification and we try to reevaluate CST and enabled the device, without actually registering it. This causes breakage as we try to create /sys fs sub directory, without the parent directory which is created at register time.

Most legacy software do not like tables > 255 as rtm_table is u8 so tb_id is sent &0xff and it is possible to mismatch for example table 510 with table 254 (main).

2008-06-10sched: fix TASK_WAKEKILL vs SIGKILL raceOleg Nesterov
schedule() has the special "TASK_INTERRUPTIBLE && signal_pending()" case, this allows us to do current->state = TASK_INTERRUPTIBLE; schedule(); without fear to sleep with pending signal. However, the code like current->state = TASK_KILLABLE; schedule(); is not right, schedule() doesn't take TASK_WAKEKILL into account. This means that mutex_lock_killable(), wait_for_completion_killable(), down_killable(), schedule_timeout_killable() can miss SIGKILL (and btw the second SIGKILL has no effect). Introduce the new helper, signal_pending_state(), and change schedule() to use it. Hopefully it will have more users, that is why the task's state is passed separately. Note this "__TASK_STOPPED | __TASK_TRACED" check in signal_pending_state(). This is needed to preserve the current behaviour (ptrace_notify). I hope this check will be removed soon, but this (afaics good) change needs the separate discussion. The fast path is "(state & (INTERRUPTIBLE | WAKEKILL)) + signal_pending(p)", basically the same that schedule() does now. However, this patch of course bloats schedule().

2008-06-09IB/core: Remove IB_DEVICE_SEND_W_INV capability flagRoland Dreier
In 2.6.26, we added some support for send with invalidate work requests, including a device capability flag to indicate whether a device supports such requests. However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

2008-06-09[POWERPC] Make walk_memory_resource available with MEMORY_HOTPLUG=nNathan Lynch
The ehea driver was recently changed[1] to use walk_memory_resource() to detect the system's memory layout. However, walk_memory_resource() is available only when memory hotplug is enabled. So CONFIG_EHEA was made to depend on MEMORY_HOTPLUG [2], but it is inappropriate for a network driver to have such a dependency. Make the declaration of walk_memory_resource() and its powerpc implementation (ehea is powerpc-specific) unconditionally available.

Migrate the PIT timer to the physical CPU which vcpu0 is scheduled on, similarly to what is done for the LAPIC timers, otherwise PIT interrupts will be delayed until an unrelated event causes an exit. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-06-05FRV: ip_fast_csum() requires a memory clobber on its inline asmDavid Howells
ip_fast_csum() requires a memory clobber on its inline asm as it accesses memory in a fashion that gcc can't predict. The GCC manual says: If your assembler instructions access memory in an unpredictable fashion, add `memory' to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. The bug hasn't been noticed in FRV, but it has been seen in PA-RISC. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
