This patch adds a new field, api_version, to hda_device_id struct, so that this information is embedded in modalias string. Although the information is basically redundant (struct hdac_device already has type field), the helper that extracts from MODULE_DEVICE_TABLE() won't take it account except for the exported table entries themselves. So we need to put the same information in the table, too.

For embedded device, we need an interface to disable it when it is not needed, to shrink the kernel size and memory footprint, here add CONFIG_SND_PCM_TIMER for it. When both CONFIG_SND_PCM_TIMER and CONFIG_SND_TIMER is unselected, about 25KB saving bonus we can get. Please be noted that when disabled, those stubs who using pcm timer (e.g. dmix, dsnoop & co) may work incorrectlly.

The address to transmit this message is stored on a certain register. This commit allocates a range of address on OHCI 1394 host controller to handle the messaging. As long as I know, the purpose of this message seems to notify lost of synchronization. While, the meaning of content of the message is not clear. Actual examples of this messaging: * When clock source is set as internal: - 0x00007051 - 0x00007052 - 0x00007054 - 0x00007057 - 0x00007058 * When clock source is set as somewhat external: - 0x00009000 - 0x00009010 - 0x00009020 - 0x00009021 - 0x00009022 The lost often occurs when using internal clock source. In this case, users hear sounds with quite short gap every several minutes. In fact, the lost is recovered temporarily. When using with external clock source, the lost seems not to occur. The mechanism is not clear yet. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

When CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has 'hwptr_log' member with a pointer to the structure. When calling xrun_log() in pcm_lib.c, the structure was allocated to the pointer. When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer is released. In f5914908a5b7 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'), the pointer logging is replaced with using Linux Kernel Tracepoints. The structure was also removed, while it's just declared. The member and kfree still remains. This commit removes the member and related codes. I think this was overlooked because it brings no errors/warnings to C compilers.

However on some boards (with S2MPS13) the pin is pulled down so any suspend will effectively trigger the reset of bucks supplying the power to the little and big cores. In the same time when resuming, these bucks must provide voltage greater or equal to voltage before suspend to match the frequency chosen by cpufreq. If voltage (default value of voltage after reset) is lower than one set by cpufreq before suspend, then system will hang during resuming.

One of usual power down methods for Exynos based devices looks like: 1. PWRHOLD pin of PMIC is connected to PSHOLD of Exynos SoC. 2. Exynos holds up this pin during system operation. 3. ACOKB pin of PMIC is pulled up to VBATT and optionally to pin in other device. 4. When PWRHOLD/PSHOLD goes low, the PMIC will turn off the power if ACOKB goes high. On Odroid XU3 family the difference is in (3) - the ACOKB is grounded. This means that PMIC must manually set PWRHOLD field to low and then wait for signal from Application Processor (the usual change in PWRHOLD/PSHOLD pin will actually cut off the power). The patch adds respective binding allowing Odroid XU3 device to be powered off.

This patch adds the ability to set this state via the new mlock system calls. We add MLOCK_ONFAULT for mlock2 and MCL_ONFAULT for mlockall. MLOCK_ONFAULT will set the VM_LOCKONFAULT modifier for VM_LOCKED. MCL_ONFAULT should be used as a modifier to the two other mlockall flags. When used with MCL_CURRENT, all current mappings will be marked with VM_LOCKED | VM_LOCKONFAULT. When used with MCL_FUTURE, the mm->def_flags will be marked with VM_LOCKED | VM_LOCKONFAULT. When used with both MCL_CURRENT and MCL_FUTURE, all current mappings and mm->def_flags will be marked with VM_LOCKED | VM_LOCKONFAULT. Prior to this patch, mlockall() will unconditionally clear the mm->def_flags any time it is called without MCL_FUTURE. This behavior is maintained after adding MCL_ONFAULT. If a call to mlockall(MCL_FUTURE) is followed by mlockall(MCL_CURRENT), the mm->def_flags will be cleared and new VMAs will be unlocked. This remains true with or without MCL_ONFAULT in either mlockall() invocation. munlock() will unconditionally clear both vma flags. munlockall() unconditionally clears for VMA flags on all VMAs and in the mm->def_flags field.

If only portions of the mapping will be used this can incur a high penalty for locking. For the example of a large file, this is the usage pattern for a large statical language model (probably applies to other statical or graphical models as well). For the security example, any application transacting in data that cannot be swapped out (credit card data, medical records, etc). This patch introduces the ability to request that pages are not pre-faulted, but are placed on the unevictable LRU when they are finally faulted in. The VM_LOCKONFAULT flag will be used together with VM_LOCKED and has no effect when set without VM_LOCKED. Setting the VM_LOCKONFAULT flag for a VMA will cause pages faulted into that VMA to be added to the unevictable LRU when they are faulted or if they are already present, but will not cause any missing pages to be faulted in. Exposing this new lock state means that we cannot overload the meaning of the FOLL_POPULATE flag any longer. Prior to this patch it was used to mean that the VMA for a fault was locked. This means we need the new FOLL_MLOCK flag to communicate the locked state of a VMA. FOLL_POPULATE will now only control if the VMA should be populated and in the case of VM_LOCKONFAULT, it will not be set. Signed-off-by: Eric B Munson <emunson@akamai.com> Acked-by: Kirill A.
