The TV detection logic is not reliable on the Cantiga platform. Sometimes the TV will be misdetected as the following two cases: - TV is misdetected on some laptops. e.g. There is no TV connector port or no TV is attached. But the TV is shown as connected. - TV connector type is misdetected. e.g. the component TV is attached, but the TV is shown as S-video type. According to the hardware requirement, the TV sense state bits of TV DAC register should be cleared to zero on Cantiga platfrom. https://bugzilla.kernel.org/show_bug.cgi?id=14792 Cc: Stable Team <stable@kernel.org> Signed-off-by:

The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver. Signed-off-by: -

In order to use disks larger than 2TiB on Windows XP, it is necessary to use 4096-byte logical sectors in an MBR. Although the kernel storage and functions called from msdos.c used "sector_t" internally, msdos.c still used u32 variables, which results in the ability to handle XP-compatible large disks. This patch changes the internal variables to "sector_t". Daniel said: "In the near future, WD will be releasing products that need this patch".

In the extended CSD register the CARD_TYPE is an 8-bit value of which the upper 6 bits were reserved in JEDEC specifications prior to version 4.4. In version 4.4 two of the reserved bits were designated for identifying support for the newly added High-Speed Dual Data Rate. Unfortunately the mmc_read_ext_csd() function required that the reserved bits be zero instead of ignoring them as it should. This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are reserved or not yet supported. It also stops the function jumping to the end as though an error occurred, when it is only warns that the CARD_TYPE bits (that it does interpret) are invalid. Signed-off-by:

The reiserfs journal behaves inconsistently when determining whether to allow a mount of a read-only device. This is due to the use of the continue_replay variable to short circuit the journal scanning. If it's set, it's assumed that there are transactions to replay, but there may not be. If it's unset, it's assumed that there aren't any, and that may not be the case either. I've observed two failure cases: 1) Where a clean file system on a read-only device refuses to mount 2) Where a clean file system on a read-only device passes the optimization and then tries writing the journal header to update the latest mount id. The former is easily observable by using a freshly created file system on a read-only loopback device. This patch moves the check into journal_read_transaction, where it can bail out before it's about to replay a transaction. That way it can go through and skip transactions where appropriate, yet still refuse to mount a file system with outstanding transactions. Signed-off-by:

Commit 57fe60df ("reiserfs: add atomic addition of selinux attributes during inode creation") contains a bug that will cause it to oops when mounting a file system that didn't previously contain extended attributes on a system using security.* xattrs. The issue is that while creating the privroot during mount reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which dereferences the xattr root. The xattr root doesn't exist, so we get an oops. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=15309Signed-off-by:

In 2.6.34-rc1, removing vhost_net module causes an oops in sync_mm_rss (called from do_exit) when workqueue is destroyed. This does not happen on net-next, or with vhost on top of to 2.6.33. The issue seems to be introduced by 34e55232 ("mm: avoid false sharing of mm_counter) which added sync_mm_rss() that is passed task->mm, and dereferences it without checking. If task is a kernel thread, mm might be NULL. I think this might also happen e.g. with aio. This patch fixes the oops by calling sync_mm_rss when task->mm is set to NULL. I also added BUG_ON to detect any other cases where counters get incremented while mm is NULL. The oops I observed looks like this: BUG: unable to handle kernel NULL pointer dereference at 00000000000002a8 IP: [<ffffffff810b436d>] sync_mm_rss+0x33/0x6f PGD 0 Oops: 0002 [#1] SMP last sysfs file: /sys/devices/system/cpu/cpu7/cache/index2/shared_cpu_map CPU 2 Modules linked in: vhost_net(-) tun bridge stp sunrpc ipv6 cpufreq_ondemand acpi_cpufreq freq_table kvm_intel kvm i5000_edac edac_core rtc_cmos bnx2 button i2c_i801 i2c_core rtc_core e1000e sg joydev ide_cd_mod serio_raw pcspkr rtc_lib cdrom virtio_net virtio_blk virtio_pci virtio_ring virtio af_packet e1000 shpchp aacraid uhci_hcd ohci_hcd ehci_hcd [last unloaded: microcode] Pid: 2046, comm: vhost Not tainted 2.6.34-rc1-vhost #25 System Planar/IBM System x3550 -[7978B3G]- RIP: 0010:[<ffffffff810b436d>] [<ffffffff810b436d>] sync_mm_rss+0x33/0x6f RSP: 0018:ffff8802379b7e60 EFLAGS: 00010202 RAX: 0000000000000008 RBX: ffff88023f2390c0 RCX: 0000000000000000 RDX: ffff88023f2396b0 RSI: 0000000000000000 RDI: ffff88023f2390c0 RBP: ffff8802379b7e60 R08: 0000000000000000 R09: 0000000000000000 R10: ffff88023aecfbc0 R11: 0000000000013240 R12: 0000000000000000 R13: ffffffff81051a6c R14: ffffe8ffffc0f540 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff880001e80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00000000000002a8 CR3: 000000023af23000 CR4: 00000000000406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process vhost (pid: 2046, threadinfo ffff8802379b6000, task ffff88023f2390c0) Stack: ffff8802379b7ee0 ffffffff81040687 ffffe8ffffc0f558 ffffffffa00a3e2d <0> 0000000000000000 ffff88023f2390c0 ffffffff81055817 ffff8802379b7e98 <0> ffff8802379b7e98 0000000100000286 ffff8802379b7ee0 ffff88023ad47d78 Call Trace: [<ffffffff81040687>] do_exit+0x147/0x6c4 [<ffffffffa00a3e2d>] ? handle_rx_net+0x0/0x17 [vhost_net] [<ffffffff81055817>] ? autoremove_wake_function+0x0/0x39 [<ffffffff81051a6c>] ? worker_thread+0x0/0x229 [<ffffffff810553c9>] kthreadd+0x0/0xf2 [<ffffffff810038d4>] kernel_thread_helper+0x4/0x10 [<ffffffff81055342>] ? kthread+0x0/0x87 [<ffffffff810038d0>] ? kernel_thread_helper+0x0/0x10 Code: 00 8b 87 6c 02 00 00 85 c0 74 14 48 98 f0 48 01 86 a0 02 00 00 c7 87 6c 02 00 00 00 00 00 00 8b 87 70 02 00 00 85 c0 74 14 48 98 <f0> 48 01 86 a8 02 00 00 c7 87 70 02 00 00 00 00 00 00 8b 87 74 RIP [<ffffffff810b436d>] sync_mm_rss+0x33/0x6f RSP <ffff8802379b7e60> CR2: 00000000000002a8 ---[ end trace 41603ba922beddd2 ]--- Fixing recursive fault but reboot is needed!
