The current kernel serializes console resizes but does not serialize the resize against the tty structure updates. This means that while two parallel resizes cannot mess up the console you can get incorrect results reported. Secondly while doing this I added vc_lock_resize() to lock and resize the console. This leaves all knowledge of the console_sem in the vt/console driver and kicks it out of the tty layer, which is good Thirdly while doing this I decided I couldn't stand "disallocate" any longer so I switched it to "deallocate".

Fat is commonly used on removable media. Mounting with -o flush tells the FS to write things to disk as quickly as possible. It is like -o sync, but much faster (and not as safe). Signed-off-by:

[assuming BSD security levels are deleted] The only user of i_security, f_security, s_security fields is SELinux, however, quite a few security modules are trying to get into kernel. So, wrap them under CONFIG_SECURITY. Adding config option for each security field is likely an overkill. Following Stephen Smalley's suggestion, i_security initialization is moved to security_inode_alloc() to not clutter core code with ifdefs and make alloc_inode() codepath tiny little bit smaller and faster. The user of (highly greppable) struct fown_struct::security field is still to be found. I've checked every "fown_struct" and every "f_owner" occurence. Additionally it's removal doesn't break i386 allmodconfig build. struct inode, struct file, struct super_block, struct fown_struct become smaller. P.S. Combined with two reiserfs inode shrinking patches sent to linux-fsdevel, I can finally suck 12 reiserfs inodes into one page. /proc/slabinfo -ext2_inode_cache 388 10 +ext2_inode_cache 384 10 -inode_cache 280 14 +inode_cache 276 14 -proc_inode_cache 296 13 +proc_inode_cache 292 13 -reiser_inode_cache 336 11 +reiser_inode_cache 332 12 <= -shmem_inode_cache 372 10 +shmem_inode_cache 368 10 Signed-off-by:

Now that the generic DMA code has a function to decide if a given DMA mapping is valid use it. This will catch cases where direction is not any of the defined enum values but some random number outside the valid range. The current implementation will only catch the defined but invalid case DMA_NONE. Signed-off-by:

This teaches dmi_decode() how to decode and save OEM Strings (type 11) DMI information, which is currently discarded silently. Existing code using DMI is not affected. Follows the "System Management BIOS (SMBIOS) Specification" (http://www.dmtf.org/standards/smbios ), and also the userspace dmidecode.c code. OEM Strings are the only safe way to identify some hardware, e.g., the ThinkPad embedded controller used by the soon-to-be-submitted tp_smapi driver. This will also let us eliminate the long whitelist in the mainline hdaps driver (in a future patch). Signed-off-by:

Convert loop.c from the deprecated kernel_thread to kthread. This patch simplifies the code quite a bit and passes similar testing to the previous submission on both emulated x86 and s390. Changes since last submission: switched to using a rather simple loop based on wait_event_interruptible. Signed-off-by:

touch_nmi_watchdog() calls touch_softlockup_watchdog() on both architectures that implement it (i386 and x86_64). On other architectures it does nothing at all. touch_nmi_watchdog() should imply touch_softlockup_watchdog() on all architectures. Suggested by Andi Kleen.

Convert the i386 summit subarch apicid_to_node to use node information provided by the SRAT. It was discussed a little on LKML a few weeks ago and was seen as an acceptable fix. The current way of obtaining the nodeid static inline int apicid_to_node(int logical_apicid) { return logical_apicid >> 5; } is just not correct for all summit systems/bios. Assuming the apicid matches the Linux node number require a leap of faith that the bios mapped out the apicids a set way. Modern summit HW (IBM x460) does not layout its bios in the manner for various reasons and is unable to boot i386 numa. The best way to get the correct apicid to node information is from the SRAT table during boot. It lays out what apicid belongs to what node. I use this information to create a table for use at run time. Signed-off-by:Keith Mannthey <kmannth@us.ibm.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by:
