* [ALSA] hda-intel - Support 64bit buffer allocationTakashi Iwai2008-04-241-0/+4
| | | | | | | The HD-audio hardware usually supports 64bit address for DMA and other buffers. The patch enables the feature if supported. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] hda-intel - Fix PCM device number assignmentTakashi Iwai2008-04-2410-44/+66
| | | | | | | | | | | | | | | | | In the current scheme, PCM device numbers are assigned incrementally in the order of codecs. This causes problems when the codec number is irregular, e.g. codec #0 for HDMI and codec #1 for analog. Then the HDMI becomes the first PCM, which is picked up as the default output device. Unfortuantely this doesn't work well with normal setups. This patch introduced the fixed device numbers for the PCM types, namely, analog, SPDIF, HDMI and modem. The PCM devices are assigned according to the corresponding PCM type. After this patch, HDMI will be always assigned to PCM #3, SPDIF to PCM #1, and the first analog to PCM #0, etc. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] Add more fallbacks to OSS PHONEOUT mixer mapTakashi Iwai2008-04-241-0/+2
| | | | | | | | Added more fallbacks to OSS PHONEOUT mixer mapping. This corresponds to the speaker output in general, so now "Mono" and "Speaker" are assigned. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] hda-codec - Allow multiple SPDIF devicesTakashi Iwai2008-04-241-2/+33
| | | | | | | | | The current code doesn't allow multiple SPDIF devices, and causes errors when multiple SPDIF devices are found (e.g. SPDIF out and HDMI). This patch allows multiple SPDIF devices by incrementing the index automatically. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [mszeredi@suse.cz] rewrite and split big patch into managable chunks /proc/mounts in its current form lacks important information: - propagation state - root of mount for bind mounts - the st_dev value used within the filesystem - identifier for each mount and it's parent It also suffers from the following problems: - not easily extendable - ambiguity of mountpoints within a chrooted environment - doesn't distinguish between filesystem dependent and independent options - doesn't distinguish between per mount and per super block options This patch introduces /proc/<pid>/mountinfo which attempts to address all these deficiencies. Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is extracted into separate functions. Thanks to Al Viro for the help in getting the design right.

| * [patch 4/7] vfs: mountinfo: add mount peer group IDMiklos Szeredi2008-04-233-4/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a unique ID to each peer group using the IDR infrastructure. The identifiers are reused after the peer group dissolves. The IDR structures are protected by holding namepspace_sem for write while allocating or deallocating IDs. IDs are allocated when a previously unshared vfsmount becomes the first member of a peer group. When a new member is added to an existing group, the ID is copied from one of the old members. IDs are freed when the last member of a peer group is unshared. Setting the MNT_SHARED flag on members of a subtree is done as a separate step, after all the IDs have been allocated. This way an allocation failure can be cleaned up easilty, without affecting the propagation state. Based on design sketch by Al Viro.

| * | [IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu2008-04-224-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it stands it's impossible to use any authentication algorithms with an ID above 31 portably. It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | IRQ resources 2" PNP_MAX_IRQ is 2 If a device invokes pnpacpi_parse_allocated_irqresource() 0, 1, or 2 times, we are happy. The 3rd time, we will fail and print "pnpacpi: exceeded the max number of IRQ resources: 2" The 4th and subsequent calls (if this ever happened) would silently scribble on irq_resource[2], which doesn't actualy exist.

| | | | | | | | | | | | | | | | | | | | | | | | The only reason to have separated __...() for those was to keep them inlined for local users in exit.c. Since Alexey removed the inline on those, there's no reason whatsoever to keep them around; just collapse with normal variants. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
