2008-06-06uml: activate_mm: remove the dead PF_BORROWED_MM checkOleg Nesterov
use_mm() was changed to use switch_mm() instead of activate_mm(), since then nobody calls (and nobody should call) activate_mm() with PF_BORROWED_MM bit set. As Jeff Dike pointed out, we can also remove the "old != new" check, it is always true.

2008-06-06ipwireless: Fix blocked sendingDavid Sterba
Packet sending is driven by two flags, tx_ready and tx_queued. It was possible, that there were queued data for sending and hardware was flagged as blocked but in fact it was not. The tx_queued was indicator but should be really a counter else first fragmented packet resets tx_queued flag, but there may be pending packets which do not get sent. New semantics: tx_ready - set, if hw is ready to send packet, no packet is being transferred right now set the flag right at the place where data are copied into hw memory and not earlier without checking if it was succesful tx_queued - count of enqueued packets, including fragments Tested-by: Michal Rokos <michal.rokos@gmail.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This patch: commit e9720acd728a46cb40daa52c99a979f7c4ff195c Author: Pavel Emelyanov <xemul@openvz.org> Date: Fri Mar 7 11:08:40 2008 -0800 [NET]: Make /proc/net a symlink on /proc/self/net (v3) introduced a /proc/self/net directory without bumping the corresponding link count for /proc/self. This patch replaces the static link count initializations with a call that counts the number of directory entries in the given pid_entry table whenever it is instantiated, and thus relieves the burden of manually keeping the two in sync.

2008-06-06doc: document the kernel-doc conventions for kernel hackersPaul Jackson
Provide documentation of the kernel-doc documentation conventions oriented to kernel hackers. Since I figure that there will be more people reading this kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the rest of the kernel, than there will be readers of this file who are documentation developers extracting that embedded kernel-doc documentation, I have taken the liberty of making the new section added here: How to format kernel-doc comments the first section of the kernel-doc-nano-HOWTO.txt file. This first section is intended to introduce, motivate and provide basic usage of the kernel-doc mechanism for kernel hackers developing other portions of the kernel.

2008-06-06atmel_serial: filter out FP during baud rate detectionHaavard Skinnemoen
I made a change to u-boot that used the FP (Fractional Part) field of BRGR to achieve more accurate baud rate generation. Unfortunately, the atmel_serial driver looks at the whole BRGR register when trying to detect the baud rate that the port is currently running at, so setting FP to a nonzero value breaks the baud rate detection. I'll sit on the u-boot patch for a while longer, but this is clearly a bug in the atmel_serial driver which should be fixed.

2008-06-06ipc: only output msgmni value at boot timeNadia Derbey
When posting: [PATCH 1/8] Scaling msgmni to the amount of lowmem (see http://lkml.org/lkml/2008/2/11/171), I have added a KERN_INFO message that is output each time msgmni is recomputed. In http://lkml.org/lkml/2008/4/29/575 Tony Luck complained that this message references an ipc namespace address that is useless. I first thought of using an audit_log instead of a printk, as suggested by Serge Hallyn. But unfortunately, we do not have any other information than the namespace address to provide here too. So I chose to move the message and output it only at boot time, removing the reference to the namespace.

But Michael Kerrisk rightly complained that this change could affect the ABI. So I'm posting this patch to make MSGPOOL expressed back in Kbytes. Michael, on his side, has fixed the man page.

2008-06-06devscgroup: make white list more compact in some casesPavel Emelyanov
Consider you added a 'c foo:bar r' permission to some cgroup and then (a bit later) 'c'foo:bar w' for it. After this you'll see the c foo:bar r c foo:bar w lines in a devices.list file. Another example - consider you added 10 'c foo:bar r' permissions to some cgroup (e.g. by mistake). After this you'll see 10 c foo:bar r lines in a list file. This is weird. This situation also has one more annoying consequence. Having many items in a white list makes permissions checking slower, sine it has to walk a longer list. The proposal is to merge permissions for items, that correspond to the same device.

2008-06-06devscgroup: relax task to dev_cgroup conversionPavel Emelyanov
Two functions, that need to get a device_cgroup from a task (they are devcgroup_inode_permission and devcgroup_inode_mknod) make it in a strange way: They get a css_set from task, then a subsys_state from css_set, then a cgroup from the state and then a subsys_state again from the cgroup. Besides, the devices_subsys_id is read from memory, whilst there's a enum-ed constant for it. Optimize this part a bit: 1. Get the subsys_stats form the task and be done - no 2 extra dereferences, 2. Use the device_subsys_id constant, not the value from memory (i.e. one less dereference). Found while preparing 2.6.26 OpenVZ port.

2008-06-06rtc-ds1374: rename device to just "ds1374"Jean Delvare
Change the name of the device from "rtc-ds1374" to just "ds1374", to match what all other RTC drivers do. I seem to remember that this name was chosen to avoid possible confusion with an older ds1374 driver, but that driver was removed 3 months ago.

2008-06-06uml: deal with inaccessible address space startTom Spink
This patch makes os_get_task_size locate the bottom of the address space, as well as the top. This is for systems which put a lower limit on mmap addresses. It works by manually scanning pages from zero onwards until a valid page is found. Because the bottom of the address space may not be zero, it's not sufficient to assume the top of the address space is the size of the address space. The size is the difference between the top address and bottom address. [jdike@addtoit.com: changed the name to reflect that this function is supposed to return the top of the process address space, not its size and changed the return value to reflect that. Also some minor formatting changes] Signed-off-by: Tom Spink <tspink@gmail.com> Signed-off-by: Jeff Dike <jdike@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Protection against the host's time going backwards (eg, ntp activity on the host) by keeping track of the time at the last tick and if it's greater than the current time, keep time stopped until the host catches up.
