| | | | | | | | | | | | | | | | | | | | | | | | | | Since udev-176, udev no longer creates device nodes under /dev and this has to be managed by the kernel devtmpfs filesystem. This means that a kernel built with the current defconfigs will not boot on a system with a recent udev. Also, enable automatic mounting of /dev for filesystems which don't manually mount it.

The way SEI was called with nt2 and nt0 consecutive broke the nt0 stuff used for channel subsystem notifications. The reason why this was broken with the mentioned patch is that you cannot selectively disable type 0 notifications (so even when asked for type 2 only, type 0 could be presented). The way to do it is to tell SEI which types of notification you can process and -this is the important part- look at the SEI result which notification type you actually received.

In order to achieve that we multiply with 125 and divide by 512. When used within sched_clock() this triggers an overflow after appr. 417 days. Resulting in a sched_clock() return value that is much smaller than previously and therefore may cause all sort of weird things in subsystems that rely on a monotonic sched_clock() behaviour. To fix this implement a tod_to_ns() helper function which converts TOD values without overflow and call this function from both places that open coded the conversion: sched_clock() and kvm_s390_handle_wait().

What has happened is that the previous call to xfs_dir2_block_compact() has rearranged things; it changes btp->count as well as the blp array. So after we make that call, we must recalculate the proper pointer to the leaf entries by making another call to xfs_dir2_block_leaf_p(). Dave provided a metadump image which led to a simple reproducer (create a particular filename in the affected directory) and this resolves the testcase as well as the bug on his live system.

However, the power_specified flag can be simply removed under the assumption that the states are always backward sorted, which is the case with the current code. This change allows the menu governor select function and the cpuidle_play_dead() to be simplified. Moreover, the set_power_states() function can removed as it does not make sense any more. Drop the power_specified flag from struct cpuidle_driver and make the related changes as described above. As a consequence, this also fixes the bug where on the dynamic C-states system, the power fields are not initialized.

The values of these two fields may be different, in which case a NULL pointer dereference may happen in cpuidle_remove_state_sysfs(), for example. Fix this problem by making cpuidle_add_state_sysfs() use device->state_count too (which restores the original behavior of it).

Fix the help text too, for all the same reasons. Sadly, -Os keeps on generating some very suboptimal code for certain cases, to the point where any I$ miss upside is swamped by the downside. The main ones are: - using "rep movsb" for memcpy, even on CPU's where that is horrendously bad for performance. - not honoring branch prediction information, so any I$ footprint you win from smaller code, you lose from less code density in the I$. - using divide instructions when that is very expensive.

But hdmi_chmap_ctl_put() returns -EBADFD when no PCM stream is assigned yet, and this results in an error message from alsactl. Although the error is harmless, it's certainly ugly and can be regarded as a regression. As a workaround, this patch changes the return code in such a case to be zero for making others happy. (A slight excuse is: when the chmap is changed through the proper alsa-lib API, the PCM status is checked there anyway, so we don't have to be too strict in the kernel side.)
