2011-03-08dsa/mv88e6060: support nonzero mii base addressPeter Korsgaard
The mv88e6060 uses either the lower 16 or upper 16 mii addresses, depending on the value of the EE_CLK/ADDR4 pin. Support both configurations by using the sw_addr setting as base address.

2011-03-08r6040: fix multicast operationsShawn Lin
The original code does not work well when the number of mulitcast address to handle is greater than MCAST_MAX. It only enable promiscous mode instead of multicast hash table mode, so the hash table function will not be activated and all multicast frames will be recieved in this condition. This patch fixes the following issues with the r6040 NIC operating in multicast: 1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC hash table registers to make it process multicast traffic. 2) When the number of multicast address to handle is smaller than MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}. 3) The hashing of the address was not correct, due to an invalid substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an incorrect crc algorithm (ether_crc_le) instead of (ether_crc). 4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast hash table function.

2011-03-08mmc: fix CONFIG_MMC_UNSAFE_RESUME regressionOhad Ben-Cohen
30201e7f3 ("mmc: skip detection of nonremovable cards on rescan") allowed skipping detection of nonremovable cards on mmc_rescan(). The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

2011-03-08ASoC: Provide CODEC clocking operations and API callsMark Brown
When multi component systems use DAIless amplifiers which require clocking configuration it is at best hard to use the current clocking API as this requires a DAI even though the device may not even have one. Address this by adding set_sysclk() and set_pll() operations and APIs for CODECs. In order to avoid issues with devices which could be used either with or without DAIs make the DAI variants call through to their CODEC counterparts if there is no DAI specific operation. Converting over entirely would create problems for multi-DAI devices which offer per-DAI clocking setup.

2011-03-08kprobes: Disabling optimized kprobes for entry text sectionJiri Olsa
You can crash the kernel (with root/admin privileges) using kprobe tracer by running: echo "p system_call_after_swapgs" > ./kprobe_events echo 1 > ./events/kprobes/enable The reason is that at the system_call_after_swapgs label, the kernel stack is not set up. If optimized kprobes are enabled, the user space stack is being used in this case (see optimized kprobe template) and this might result in a crash. There are several places like this over the entry code (entry_$BIT). As it seems there's no any reasonable/maintainable way to disable only those places where the stack is not ready, I switched off the whole entry code from kprobe optimizing.

2011-03-08x86: Separate out entry text sectionJiri Olsa
Put x86 entry code into a separate link section: .entry.text. Separating the entry text section seems to have performance benefits - caused by more efficient instruction cache usage. Running hackbench with perf stat --repeat showed that the change compresses the icache footprint. The icache load miss rate went down by about 15%: before patch: 19417627 L1-icache-load-misses ( +- 0.147% ) after patch: 16490788 L1-icache-load-misses ( +- 0.180% ) The motivation of the patch was to fix a particular kprobes bug that relates to the entry text section, the performance advantage was discovered accidentally. Whole perf output follows: - results for current tip tree: Performance counter stats for './hackbench/hackbench 10' (500 runs): 19417627 L1-icache-load-misses ( +- 0.147% ) 2676914223 instructions # 0.497 IPC ( +- 0.079% ) 5389516026 cycles ( +- 0.144% ) 0.206267711 seconds time elapsed ( +- 0.138% ) - results for current tip tree with the patch applied: Performance counter stats for './hackbench/hackbench 10' (500 runs): 16490788 L1-icache-load-misses ( +- 0.180% ) 2717734941 instructions # 0.502 IPC ( +- 0.079% ) 5414756975 cycles ( +- 0.148% ) 0.206747566 seconds time elapsed ( +- 0.137% ) Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Nick Piggin <npiggin@kernel.dk> Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: masami.hiramatsu.pt@hitachi.com Cc: ananth@in.ibm.com Cc: davem@davemloft.net Cc: 2nddept-manager@sdl.hitachi.co.jp LKML-Reference: <20110307181039.GB15197@jolsa.redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

In complex subsystems like mac80211 structures can contain several timers and work structs, so identifying a specific instance from the call trace and object type output of debugobjects can be hard. Allow the subsystems which support debugobjects to provide a hint function.

The purpose of the snd_ctl_hole_check() function is to find conflicts between the numerical IDs of the new control and those of any existing controls. However, it would fail to detect an existing control whose count is smaller than the new control's count and whose interval of IDs is entirely contained in the interval of the new control's IDs. To fix this, use the correct formula to detect overlapping intervals, which happens to simplify the condition.

2011-03-08UBIFS: use max_write_size during recoveryArtem Bityutskiy
When recovering from unclean reboots UBIFS scans the journal and checks nodes. If a corrupted node is found, UBIFS tries to check if this is the last node in the LEB or not. This is is done by checking if there only 0xFF bytes starting from the next min. I/O unit. However, since now we write in c->max_write_size, we should actually check for 0xFFs starting from the next max. write unit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-03-08UBIFS: use max_write_size for write-buffersArtem Bityutskiy
Switch write-buffers from 'c->min_io_size' to 'c->max_write_size' which presumably has to be more write speed-efficient. However, when write-buffer is synchronized, write only the the min. I/O units which contain the data, do not write whole write-buffer. This is more space-efficient. Additionally, this patch takes into account that the LEB might not start from the max. write unit-aligned address. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-03-08UBIFS: introduce write-buffer size fieldArtem Bityutskiy
Currently we assume write-buffer size is always min_io_size. But this is about to change and write-buffers may be of variable size. Namely, they will be of max_write_size at the beginning, but will get smaller when we are approaching the end of LEB. This is a preparation patch which introduces 'size' field in the write-buffer structure which carries the current write-buffer size. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2011-03-08unfuck proc_sysctl ->d_compare()Al Viro
a) struct inode is not going to be freed under ->d_compare(); however, the thing PROC_I(inode)->sysctl points to just might. Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it! Said that, I really suspect that this check can be simply killed. Nick? Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Even though userland tools can get the block count via nilfs_get_cpinfo ioctl, it was not updated by the nilfs2 kernel code. This fixes the issue and makes it available for userland tools to calculate used amount per checkpoint. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Jiro SEKIBA <jir@unicus.jp>
2011-03-08nilfs2: optimize rec_len functionsRyusuke Konishi
This is a similar change to those in ext2/ext3 codebase (commit 40a063f6691ce937 and a4ae3094869f18e2, respectively). The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks. This will cut the corner. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
