* W1: w1_process, block or sleepDavid Fries2008-10-16
| | | | | | | | | | | | | | | | The w1_process thread's sleeping and termination has been modified. msleep_interruptible was replaced by schedule_timeout and schedule to allow for kthread_stop and wake_up_process to interrupt the sleep and the unbounded sleeping when a bus search is disabled. The W1_MASTER_NEED_EXIT and flags variable were removed as they were redundant with kthread_should_stop and kthread_stop. If w1_process is sleeping, requesting a search will immediately wake it up rather than waiting for the end of msleep_interruptible previously.

* W1: don't delay search startDavid Fries2008-10-16
| | | | | | | | | | | | | | | Move the creation of the w1_process thread to after the device has been initialized. This way w1_process doesn't have to check to see if it has been initialized and the bus search can proceed without sleeping. That also eliminates two checks in the w1_process loop. The sleep now happens at the end of the loop not the beginning. Also added a comment for why the atomic_set was 2.

* W1: abort search early on on exitDavid Fries2008-10-16
| | | | | | | | | | | Early abort if the master driver or the hardware goes away in the middle of a bus search operation.

* W1: fix deadlocks and remove w1_control_threadDavid Fries2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | w1_control_thread was removed which would wake up every second and process newly registered family codes and complete some final cleanup for a removed master. Those routines were moved to the threads that were previously requesting those operations. A new function w1_reconnect_slaves takes care of reconnecting existing slave devices when a new family code is registered or removed. The removal case was missing and would cause a deadlock waiting for the family code reference count to decrease, which will now happen. A problem with registering a family code was fixed. A slave device would be unattached if it wasn't yet claimed, then attached at the end of the list, two unclaimed slaves would cause an infinite loop. The struct w1_bus_master.search now takes a pointer to the struct w1_master device to avoid searching for it, which would have caused a lock ordering deadlock with the removal of w1_control_thread.

* tpm: work around bug in Broadcom BCM0102 chipsetValdis Kletnieks2008-10-16
| | | | | | | | | | | | | | | | | Patch tpm-correct-tpm-timeouts-to-jiffies-conversion reveals a bug in the Broadcom BCM0102 TPM chipset used in the Dell Latitude D820 - although most of the timeouts are returned in usecs as per the spec, one is apparently returned in msecs, which results in a too-small value leading to a timeout when the code treats it as usecs. To prevent a regression, we check for the known too-short value and adjust it to a value that makes things work.

* tpm: correct tpm timeouts to jiffies conversionMarcin Obara2008-10-16
| | | | | | | | | | | | | | | | | | This patch fixes timeouts conversion to jiffies, by replacing msecs_to_jiffies() calls with usecs_to_jiffies(). According to TCG TPM Specification Version 1.2 Revision 103 (pages 166, 167) TPM timeouts and durations are returned in microseconds (usec) not in miliseconds (msec). This fixes a long hang while loading TPM driver, if TPM chip starts in "Idle" state instead of "Ready" state. Without this patch - 'modprobe' may hang for 30 seconds or more.

* hfsplus: fix Buffer overflow with a corrupted imageEric Sesterhenn2008-10-16

* ext2: avoid printk floods in the face of directory corruptionEric Sandeen2008-10-16
| | | | | | | | | | | | | | | | | | A very large directory with many read failures (either due to storage problems, or due to invalid size & blocks from corruption) will generate a printk storm as the filesystem continues to try to read all the blocks. This flood of messages can tie up the box until it is complete - which may be a very long time, especially for very large corrupted values. This is fixed by only reporting the corruption once each time we try to read the directory.

* ext2: fix ext2 block reservation early ENOSPC issueMingming Cao2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We could run into ENOSPC error on ext2, even when there is free blocks on the filesystem. The problem is triggered in the case the goal block group has 0 free blocks , and the rest block groups are skipped due to the check of "free_blocks < windowsz/2". Current code could fall back to non reservation allocation to prevent early ENOSPC after examing all the block groups with reservation on , but this code was bypassed if the reservation window is turned off already, which is true in this case. This patch fixed two issues: 1) We don't need to turn off block reservation if the goal block group has 0 free blocks left and continue search for the rest of block groups. Current code the intention is to turn off the block reservation if the goal allocation group has a few (some) free blocks left (not enough for make the desired reservation window),to try to allocation in the goal block group, to get better locality. But if the goal blocks have 0 free blocks, it should leave the block reservation on, and continues search for the next block groups,rather than turn off block reservation completely. 2) we don't need to check the window size if the block reservation is off. The problem was originally found and fixed in ext4.

| | | | | | | | | | | | | | | | | Make alloc_carmine_fb() __devinit. WARNING: drivers/video/carminefb.o(.text+0x81b): Section mismatch in reference from the function alloc_carmine_fb() to the variable .devinit.data:carminefb_fix The function alloc_carmine_fb() references the variable __devinitdata carminefb_fix. This is often because alloc_carmine_fb lacks a __devinitdata annotation or the annotation of carminefb_fix is wrong.

* fbdev: ignore VESA modes if framebuffer does not support themMichal Januszewski2008-10-16
| | | | | | | | | | | | | | | | Currently, it is possible to set a graphics VESA mode at boot time via the vga= parameter even when no framebuffer driver supporting this is configured. This could lead to the system booting with a black screen, without a usable console. Fix this problem by only allowing to set graphics modes at boot time if a supporting framebuffer driver is configured.
