As in commit f21afc25 ("smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu()"), we don't want to enable irqs if they are not already enabled. I don't know of any bugs currently caused by this unconditional local_irq_enable(), but I want to use this function in MIPS/OCTEON early boot (when we have early_boot_irqs_disabled). This also makes this function have similar semantics to on_each_cpu() which is good in itself. Signed-off-by:

At least on ARM no-MMU the extable is empty and so there is nothing to sort. So add a check for the table to be empty which effectively only changes that the misleading pr_notice is suppressed. Signed-off-by:

All of the other non-trivial !SMP versions of functions in smp.h are out-of-line in up.c. Move on_each_cpu() there as well. This allows us to get rid of the #include <linux/irqflags.h>. The drawback is that this makes both the x86_64 and i386 defconfig !SMP kernels about 200 bytes larger each. Signed-off-by:

The SMP version of this function doesn't unconditionally enable irqs, so neither should this !SMP version. There are no know problems caused by this, but we make the change for consistency's sake. Signed-off-by:

As in commit f21afc25 ("smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu()"), we don't want to enable irqs if they are not already enabled. There are currently no known problematical callers of these functions, but since it is a known failure pattern, we preemptively fix them. Since they are not trivial functions, make them non-inline by moving them to up.c. This also makes it so we don't have to fix #include dependancies for preempt_{disable,enable}. Signed-off-by:

When running with GENERIC_LOCKBREAK=y, the locking implementations emit calls to arch_{read,write,spin}_relax when spinning on a contended lock in order to allow architectures to favour the CPU owning the lock if possible. In reality, everybody apart from PowerPC and S390 just does cpu_relax() here, so make that the default behaviour and allow it to be overridden if required.

I found the following pattern that leads in to interesting findings: grep -r "ret.*|=.*__put_user" * grep -r "ret.*|=.*__get_user" * grep -r "ret.*|=.*__copy" * The __put_user() calls in compat_ioctl.c, ptrace compat, signal compat, since those appear in compat code, we could probably expect the kernel addresses not to be reachable in the lower 32-bit range, so I think they might not be exploitable. For the "__get_user" cases, I don't think those are exploitable: the worse that can happen is that the kernel will copy kernel memory into in-kernel buffers, and will fail immediately afterward. The alpha csum_partial_copy_from_user() seems to be missing the access_ok() check entirely. The fix is inspired from x86. This could lead to information leak on alpha. I also noticed that many architectures map csum_partial_copy_from_user() to csum_partial_copy_generic(), but I wonder if the latter is performing the access checks on every architectures.

pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from pnp_driver. Changed pnp_bus_suspend() and pnp_bus_resume() to check if pnp driver has dev_pm_ops and call. If dev_pm_ops don't exist, then call use legacy pm_ops. Without this change, pnp_driver dev_pm_ops will not get called. In addition to the pnp driver bus pm_ops change to invoke driver dev_pm_ops, this patch set contains changes to rtc-cmos, tpm_tis, and apple-gmux pnp drivers to convert from legacy pm_ops to dev_pm_ops. This patch (of 4): pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from pnp_driver. Changed pnp_bus_suspend() and pnp_bus_resume() to check if pnp driver has dev_pm_ops and call. If dev_pm_ops don't exist, then call use legacy pm_ops. Without this change, pnp_driver dev_pm_ops will not get called. Signed-off-by:

A memory cgroup with (1) multiple threshold notifications and (2) at least one threshold >=2G was not reliable. Specifically the notifications would either not fire or would not fire in the proper order. The __mem_cgroup_threshold() signaling logic depends on keeping 64 bit thresholds in sorted order. mem_cgroup_usage_register_event() sorts them with compare_thresholds(), which returns the difference of two 64 bit thresholds as an int. If the difference is positive but has bit[31] set, then sort() treats the difference as negative and breaks sort order. This fix compares the two arbitrary 64 bit thresholds returning the classic -1, 0, 1 result. The test below sets two notifications (at 0x1000 and 0x81001000): cd /sys/fs/cgroup/memory mkdir x for x in 4096 2164264960; do cgroup_event_listener x/memory.usage_in_bytes $x | sed "s/^/$x listener:/" & done echo $$ > x/cgroup.procs anon_leaker 500M v3.11-rc7 fails to signal the 4096 event listener: Leaking... Done leaking pages. Patched v3.11-rc7 properly notifies: Leaking... 4096 listener:2013:8:31:14:13:36 Done leaking pages. The fixed bug is old. It appears to date back to the introduction of memcg threshold notifications in v2.6.34-rc1-116-g2e72b634 "memcg: implement memory thresholds" Signed-off-by:Greg Thelen <gthelen@google.com> Acked-by:
