This allows us to change the representation (to a dangling bitmap or cpumask_var_t) without breaking all the callers: they can use tsk_cpumask() now and won't see a difference as the changes roll into linux-next. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

CLONE_PARENT can fool the ->self_exec_id/parent_exec_id logic. If we re-use the old parent, we must also re-use ->parent_exec_id to make sure exit_notify() sees the right ->xxx_exec_id's when the CLONE_PARENT'ed task exits. Also, move down the "p->parent_exec_id = p->self_exec_id" thing, to place two different cases together.

This reverts commit e088e4c9. Removing the sysfs interface for p4-clockmod was flagged as a regression in bug 12826. Course of action: - Find out the remaining causes of overheating, and fix them if possible. ACPI should be doing the right thing automatically. If it isn't, we need to fix that. - mark p4-clockmod ui as deprecated - try again with the removal in six months. It's not really feasible to printk about the deprecation, because it needs to happen at all the sysfs entry points, which means adding a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

btrfs_tree_locked was being used to make sure a given extent_buffer was properly locked in a few places. But, it wasn't correct for UP compiled kernels. This switches it to using assert_spin_locked instead, and renames it to btrfs_assert_tree_locked to better reflect how it was really being used. Signed-off-by: Chris Mason <chris.mason@oracle.com>

So in acct_update_integrals we may end up with the following scenario: Between reading tsk->stime/tsk->utime and tsk->acct_timexpd an interrupt happens which updates accouting values. This causes acct_timexpd to be greater than the former stime + utime. The subsequent calculation of dtime = cputime_sub(time, tsk->acct_timexpd); will be negative and the division performed by cputime_to_jiffies(dtime) will generate an exception since the result won't fit into a 32 bit register. In order to fix this just always disable interrupts while accessing any of the accounting values.

Impact: remove lots of lguest boot WARN_ON() when CONFIG_SPARSE_IRQ=y We now need to call irq_to_desc_alloc_cpu() before set_irq_chip_and_handler_name(), but we can't do that from init_IRQ (no kmalloc available). So do it as we use interrupts instead. Also means we only alloc for irqs we use, which was the intent of CONFIG_SPARSE_IRQ anyway.

Impact: fix lguest boot crash on modern Intel machines The code in early_init_intel does: if (c->x86 > 6 || (c->x86 == 6 && c->x86_model >= 0xd)) { u64 misc_enable; rdmsrl(MSR_IA32_MISC_ENABLE, misc_enable); And that rdmsr faults (not allowed from non-0 PL). We can get around this by mugging the family ID part of the cpuid. 5 seems like a good number. Of course, this is a hack (how very lguest!). We could just indicate that we don't support MSRs, or implement lguest_rdmst.

This is a build fix required after "x86-64: seccomp: fix 32/64 syscall hole" (commit 5b101740). MIPS doesn't have the issue that was fixed for x86-64 by that patch. This also doesn't solve the N32 issue which is that N32 seccomp processes will be treated as non-compat processes thus only have access to N64 syscalls.

In case a ptraced task is reaped (while the tracer is still attached), ds_exit_thread() is called before ptrace_exit(). The latter will release the bts_tracer and remove the thread's ds_ctx. The former will WARN() if the context is not NULL. Oleg Nesterov submitted patches that move ptrace_exit() before exit_thread() and thus reverse the order of the above calls. Remove the bad warning.

orion5x_wdt no longer compiled after the changes in commit ebe35aff ("Orion: prepare for runtime-determined timer tick rate"). The tick rate define (ORION5X_TCLK) was removed in favor of a runtime detection. The quick fix is to add the define in the watchdog driver. The fix is not correct for all supported orion5x platforms, but since the supported platforms right now are 133 Mhz and 166 Mhz, it won't be _that_ far off. ;-) A fix that uses the runtime-determined timer tick rate will be applied later.
