commit 3fbf586c upstream. 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".

commit 1082f57a upstream. The EHCI driver stores in usb_host_endpoint.hcpriv a pointer to either an ehci_qh or an ehci_iso_stream structure, and uses the contents of the hw_info1 field to distinguish the two cases. After ehci_qh was split into hw and sw parts, ehci_iso_stream must also be adjusted so that it again looks like an ehci_qh structure. This fixes a NULL pointer access in ehci_endpoint_disable() when it tries to access qh->hw->hw_info1. Signed-off-by:

commit 92bc3648 upstream. When isochronous URBs are shorter than one frame and when more than one ITD in a frame has been completed before the interrupt can be handled, scan_periodic() completes the URBs in the order in which they are found in the descriptor list. Therefore, the descriptor list must contain the ITDs in the correct order, i.e., a new ITD must be linked in after any previous ITDs of the same endpoint. This should fix garbled capture data in the USB audio drivers. Signed-off-by:

commit 7152b592 upstream. This patch (as1352) fixes a bug in the way isochronous input data is returned to userspace for usbfs transfers. The entire buffer must be copied, not just the first actual_length bytes, because the individual packets will be discontiguous if any of them are short. Reported-by:

commit 352fa6ad upstream. The TTY layer takes some care to ensure that only sub-page allocations are made with interrupts disabled. It does this by setting a goal of "TTY_BUFFER_PAGE" to allocate. Unfortunately, while TTY_BUFFER_PAGE takes the size of tty_buffer into account, it fails to account that tty_buffer_find() rounds the buffer size out to the next 256 byte boundary before adding on the size of the tty_buffer. This patch adjusts the TTY_BUFFER_PAGE calculation to take into account the size of the tty_buffer and the padding. Once applied, tty_buffer_alloc() should not require high-order allocations.

commit d9661adf upstream. We allocate during interrupts so while our buffering is normally diced up small anyway on some hardware at speed we can pressure the VM excessively for page pairs. We don't really need big buffers to be linear so don't try so hard. In order to make this work well we will tidy up excess callers to request_room, which cannot itself enforce this break up.

commit 0d9dc7c8 upstream. The issue occur while deleting 60 virtual ports through the sys interface /sys/class/fc_vports/vport-X/vport_delete. It happen while in a mistake each request sent twice for the same vport. This interface is asynchronous, entering the delete request into a work queue, allowing more than one request to enter to the delete work queue. The result is a NULL pointer. The first request already delete the vport, while the second request got a pointer to the vport before the device destroyed. Re-create vport later cause system freeze. Solution: Check vport flags before entering the request to the work queue. [jejb: fixed int<->long problem on spinlock flags variable] Signed-off-by:

commit 413b43de upstream. Fix an 'oops' when a tmpfs mount point is mounted with the mpol=default mempolicy. Upon remounting a tmpfs mount point with 'mpol=default' option, the mount code crashed with a null pointer dereference. The initial problem report was on 2.6.27, but the problem exists in mainline 2.6.34-rc as well. On examining the code, we see that mpol_new returns NULL if default mempolicy was requested. This 'NULL' mempolicy is accessed to store the node mask resulting in oops. The following patch fixes it. Signed-off-by:

commit 220b140b upstream. Anton Blanchard found that he could reliably make the kernel hit a BUG_ON in the slab allocator by taking a cpu offline and then online while a system-wide perf record session was running. The reason is that when the cpu comes up, we completely reinitialize the ctx field of the struct perf_cpu_context for the cpu. If there is a system-wide perf record session running, then there will be a struct perf_event that has a reference to the context, so its refcount will be 2. (The perf_event has been removed from the context's group_entry and event_entry lists by perf_event_exit_cpu(), but that doesn't remove the perf_event's reference to the context and doesn't decrement the context's refcount.) When the cpu comes up, perf_event_init_cpu() gets called, and it calls __perf_event_init_context() on the cpu's context. That resets the refcount to 1. Then when the perf record session finishes and the perf_event is closed, the refcount gets decremented to 0 and the context gets kfreed after an RCU grace period. Since the context wasn't kmalloced -- it's part of a per-cpu variable -- bad things happen. In fact we don't need to completely reinitialize the context when the cpu comes up. It's sufficient to initialize the context once at boot, but we need to do it for all possible cpus. This moves the context initialization to happen at boot time. With this, we don't trash the refcount and the context never gets kfreed, and we don't hit the BUG_ON. Reported-by:

commit 1c583063 upstream. When the CMI8738 FRAME2 register is read, the chip sometimes (probably when wrapping around) returns an invalid value that would be outside the programmed DMA buffer. This leads to an inconsistent PCM pointer that is likely to result in an underrun. To work around this, read the register multiple times until we get a valid value; the error state seems to be very short-lived. Signed-off-by:
