2009-04-01fbmem: fix fb_info->lock and mm->mmap_sem circular locking dependencyAndrea Righi
Fix a circular locking dependency in the frame buffer console driver pushing down the mutex fb_info->lock. Circular locking dependecies occur calling the blocking fb_notifier_call_chain() with fb_info->lock held. Notifier callbacks can try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the reverse order mm->mmap_sem => fb_info->lock.

- The Laguna GD5465 (AGP) has one register more than non-AGP chips. Recognize the AGP version and write a tile control register only on the AGP version. Tested only on an AGP card. - Bump up RAMDAC frequencies after X11 code. This allow to drive a flat panel resolution 1680x1050 at 16bpp from the 4MB card. - Fix screen start address overflow bits on Laguna cards (CRT1D register). - Fix exit path in the cirrusfb_pci_register() in case of error.

Break cirrusfb_decode_var() function into two parts: cirrusfb_check_pixclock() which can be called from the cirrusfb_check_var() aand merge rest into the cirrusfb_set_par_foo(). This allows rejecting modes with too high pixclock before before any change to hardware state (and a console is messed up). Also, fix RGB field's lengths for 8bpp modes to correct ones so X11 works with fbdev driver with cirrusfb. Kill some redundant function calls or register loads.

2009-04-01cirrusfb: add mmio registers for Laguna chipsetsKrzysztof Helt
The Laguna chipsets use special registers which are available through the mmio area. The cirrusfb driver does not use memory mapped registers for the PCI cards. Add the memory mapped area for Laguna chipsets and add basic usage of the special Laguna registers after SVGALIB code. This gives readable console at 16bpp on the GD-5465 (Laguna AGP).

2009-04-01autofs4: fix lookup deadlockIan Kent
A deadlock can occur when user space uses a signal (autofs version 4 uses SIGCHLD for this) to effect expire completion. The order of events is: Expire process completes, but before being able to send SIGCHLD to it's parent ... Another process walks onto a different mount point and drops the directory inode semaphore prior to sending the request to the daemon as it must ... A third process does an lstat on on the expired mount point causing it to wait on expire completion (unfortunately) holding the directory semaphore. The mount request then arrives at the daemon which does an lstat and, deadlock. For some time I was concerned about releasing the directory semaphore around the expire wait in autofs4_lookup as well as for the mount call back. I finally realized that the last round of changes in this function made the expiring dentry and the lookup dentry separate and distinct so the check and possible wait can be done anywhere prior to the mount call back. This patch moves the check to just before the mount call back and inside the directory inode mutex release.

The bindings describes a case where MMC/SD/SDIO slot directly connected to a SPI bus. Such setups are widely used on embedded PowerPC boards. The patch also adds the mmc-spi-slot entry to the OpenFirmware modalias table.

2009-04-01spi_mpc83xx: add OF platform driver bindingsAnton Vorontsov
Implement full support for OF SPI bindings. Now the driver can manage its own chip selects without any help from the board files and/or fsl_soc constructors. The "legacy" code is well isolated and could be removed as time goes by.
