2012-03-08tty: serial: OMAP: Fix oops due to NULL pdata in DT bootCousson, Benoit
The following commit: be4b0281956c5cae4f63f31f11d07625a6988766 (tty: serial: OMAP: block idle while the UART is transferring data in PIO mode), is introducing an oops if OMAP is booted using device tree blob because the pdata will not be initialized. Check if pdata is set before de-referencing it.

2012-03-08vt:tackle kbd_tableAlan Cox
Keyboard struct lifetime is easy, but the locking is not and is completely ignored by the existing code. Tackle this one head on - Make the kbd_table private so we can run down all direct users - Hoick the relevant ioctl handlers into the keyboard layer - Lock them with the keyboard lock so they don't change mid keypress - Add helpers for things like console stop/start so we isolate the poking around properly - Tweak the braille console so it still builds There are a couple of FIXME locking cases left for ioctls that are so hideous they should be addressed in a later patch. After this patch the kbd_table is private and all the keyboard jiggery pokery is in one place. This update fixes speakup and also a memory leak in the original.

2012-03-08viafb: avoid refresh and mode lookup in set_parFlorian Tobias Schandinat
As check_var already ensures that the mode is valid there is no need to do those expensive lookups here again.

2012-03-08viafb: modetable conversionFlorian Tobias Schandinat
This patch converts the modetables used in viafb to - remove the strange thing that sync_end and blanking_end contained the length and not the absolute value - remove hundreds of useless defines - use fb_videomode and not our own definition so modes defined in the subsystem and received via EDID are compatible with ours As the modes are now stored in a flat structure and no longer in a tree like thing the lookup time was increased but as it is a rare event anyway it shouldn't matter. Otherwise the behaviour should be the same as before. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2012-03-08staging: android: ram_console: honor dmesg_restrictNick Kralevich
The Linux kernel has a setting called dmesg_restrict. When true, only processes with CAP_SYSLOG can view the kernel dmesg logs. This helps prevent leaking of kernel information into user space. On Android, it's possible to bypass these restrictions by viewing /proc/last_kmsg. This change makes /proc/last_kmsg require the same permissions as dmesg.

It handles ecc on the data to correct bit errors introduced during reboot. ram_console is now a small wrapper around persistent_ram that feeds console data into the ringbuffer, and exports the old data to /proc/last_kmsg after a reboot.

2012-03-08[media] smsdvb: fix get_frontendGianluca Gennari
In the get_frontend function, an internal copy of the dtv_frontend_properties struct (which is never initialized) is copied over the frontend property cache data structure, resetting everything to 0. In particular, the delivery system is reset to 0 (which is an invalid value) so the driver stops working as soon as a DVBv3 application calls the get_frontend function, giving this error: dvb_frontend_ioctl_legacy: doesn't know how to handle a DVBv3 call to delivery system 0 This patch eliminates the unused internal copy of the dtv_frontend_properties struct, and gives a proper implementation of the get_frontend function. The original author of the patch is Panagiotis Malakoudis, who also tested this new version on Ubuntu 11.10 with the latest media_build tree installed. The original patch has been used on MIPS set-top-boxes for over one year, but it was never posted on the linux-media list. I ported the code to the current media_build tree (converting it to use the dtv_frontend_properties struct) and added basic support for ISDB-T (untested).

2012-03-08GFS2: Remove a __GFP_NOFAIL allocationSteven Whitehouse
In order to ensure that we've got enough buffer heads for flushing the journal, the orignal code used __GFP_NOFAIL when performing this allocation. Here we dispense with that in favour of using a mempool. This should improve efficiency in low memory conditions since flushing the journal is a good way to get memory back, we don't want to be spinning, waiting on memory allocations. The buffers which are allocated via this mempool are fairly short lived, so that we'll recycle them pretty quickly. Although there are other memory allocations which occur during the journal flush process, this is the one which can potentially require the most memory, so the most important one to fix. The amount of memory reserved is a fixed amount, and we should not need to scale it when there are a greater number of filesystems in use. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

While for a user mode register dump it may be reasonable to skip those (albeit x86-64 doesn't do so), for kernel mode dumps these should be printed to make sure all information possibly necessary for analysis is available.

2012-03-08x86: Tighten dependencies of CPU_SUP_*_32Jan Beulich

2012-03-08inetpeer: Invalidate the inetpeer tree along with the routing cacheSteffen Klassert
We initialize the routing metrics with the values cached on the inetpeer in rt_init_metrics(). So if we have the metrics cached on the inetpeer, we ignore the user configured fib_metrics. To fix this issue, we replace the old tree with a fresh initialized inet_peer_base. The old tree is removed later with a delayed work queue.
