* kgdbts: unify/generalize gdb breakpoint adjustmentMike Frysinger2011-05-273-0/+3
| | | | | | | | | | | | | | | | | | | The Blackfin arch, like the x86 arch, needs to adjust the PC manually after a breakpoint is hit as normally this is handled by the remote gdb. However, rather than starting another arch ifdef mess, create a common GDB_ADJUSTS_BREAK_OFFSET define for any arch to opt-in via their kgdb.h.

* cgroup: remove the ns_cgroupDaniel Lezcano2011-05-2711-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal. Since that time we have heard from XXX users who were affected by this. Signed-off-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: Serge E. Hallyn <serge.hallyn@canonical.com> Cc: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vread_tsc is short and hot, and it's userspace code so the usual reasons to enable -pg and turn off sibling calls don't apply. (OK, turning off sibling calls has no effect. But it might someday...) As an added benefit, tsc.c is profilable now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vclock_gettime's do_monotonic helper can't ever generate a negative nsec value, so it doesn't need to check whether it's negative. In the CLOCK_MONOTONIC_COARSE case, ns can't ever exceed 2e9-1, so we can avoid the loop entirely. This saves a single easily-predicted branch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vread_tsc checks whether rdtsc returns something less than cycle_last, which is an extremely predictable branch. GCC likes to generate a cmov anyway, which is several cycles slower than a predicted branch. This saves a couple of nanoseconds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RDTSC is completely unordered on modern Intel and AMD CPUs. The Intel manual says that lfence;rdtsc causes all previous instructions to complete before the tsc is read, and the AMD manual says to use mfence;rdtsc to do the same thing. From a decent amount of testing [1] this is enough to make rdtsc be ordered with respect to subsequent loads across a wide variety of CPUs. On Sandy Bridge (i7-2600), this improves a loop of clock_gettime(CLOCK_MONOTONIC) by more than 5 ns/iter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variables that are shared between the vdso and the kernel are currently a bit of a mess. They are each defined with their own magic, they are accessed differently in the kernel, the vsyscall page, and the vdso, and one of them (vsyscall_clock) doesn't even really exist. This changes them all to use a common mechanism. All of them are delcared in vvar.h with a fixed address (validated by the linker script). In the kernel (as before), they look like ordinary read-write variables. In the vsyscall page and the vdso, they are accessed through a new macro VVAR, which gives read-only access. The vdso is now loaded verbatim into memory without any fixups. As a side bonus, access from the vdso is faster because a level of indirection is removed. While we're at it, pack jiffies and vgetcpu_mode into the same cacheline.

Using those structures is redundant to the structs used by the cpuidle framework. This patch provides a clean-up of the internal struct, removes the internal C-states array, stores the data using the existing cpuidle per C-state struct and registers the mach specific data to cpuidle C-state driver_data (accessed using cpuidle_[gs]et_statedata). Also removes unused macros, fields and code and compacts the repeating code using an inline helper function. The result is more compact and more readable code as well as reduced data RAM usage. Also retain C1 as the only always valid C-state and system safe state. Signed-off-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cpuidle states settings can be overriden by some board- specific settings, by calling omap3_pm_init_cpuidle. Remove the 3430SDP specific states settings registration since the figures are identical to the default ones (in cpuidle34xx.c).
