2013-08-05ath9k: Remove ath_ant_comb_update()Sujith Manoharan
During a HW reset, the diversity config is programmed in the set_board_values() eeprom callback, there is no need to do it again by calling ath_ant_comb_update(). Fixed antenna support is not fully handled for 1-stream cards, it can be done later. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

The idea is to make the interface future-proof so we can add flags and not new fields. However, flags value isn't validated, as a result, userspace can't detect which flags are supported.

2013-08-05ath10k: fix device teardownMichal Kazior
This fixes interrupt-related issue when no interfaces were running thus the device was considered powered down. The power_down() function isn't really powering down the device. It simply assumed it won't interrupt. This wasn't true in some cases and could lead to paging failures upon FW indication interrupt (i.e. FW crash) because some structures aren't allocated in that device state. One reason for that was that ar_pci->started wasn't reset. The other is interrupts should've been masked when teardown starts. The patch reorganized interrupt setup and makes sure ar_pci->started is reset accordingly.

2013-08-05regmap: cache: Make sure to sync the last register in a blockLars-Peter Clausen
regcache_sync_block_raw_flush() expects the address of the register after last register that needs to be synced as its parameter. But the last call to regcache_sync_block_raw_flush() in regcache_sync_block_raw() passes the address of the last register in the block. This effectively always skips over the last register in a block, even if it needs to be synced. In order to fix it increase the address by one register. The issue was introduced in commit 75a5f89 ("regmap: cache: Write consecutive registers in a single block write").

2013-08-05fs: Allow unprivileged linkat(..., AT_EMPTY_PATH) aka flinkAndy Lutomirski
Every now and then someone proposes a new flink syscall, and this spawns a long discussion of whether it would be a security problem. I think that this is missing the point: flink is *already* allowed without privilege as long as /proc is mounted -- it's called AT_SYMLINK_FOLLOW. Now that O_TMPFILE is here, the ability to create a file with O_TMPFILE, write it, and link it in is very convenient. The only problem is that it requires that /proc be mounted so that you can do: linkat(AT_FDCWD, "/proc/self/fd/<tmpfd>", dfd, path, AT_SYMLINK_NOFOLLOW) This sucks -- it's much nicer to do: linkat(tmpfd, "", dfd, path, AT_EMPTY_PATH) Let's allow it. If this turns out to be excessively scary, it we could instead require that the inode in question be I_LINKABLE, but this seems pointless given the /proc situation Signed-off-by: Andy Lutomirski <luto@amacapital.net> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-08-05fs: Fix file mode for O_TMPFILEAndy Lutomirski

This fixes two bugs: O_TMPFILE required privilege (because the mode ended up as 000) and it produced bogus inodes with no type.

2013-08-05reiserfs: fix deadlock in umountAl Viro
Since remove_proc_entry() started to wait for IO in progress (i.e. since 2007 or so), the locking in fs/reiserfs/proc.c became wrong; if procfs read happens between the moment when umount() locks the victim superblock and removal of /proc/fs/reiserfs/<device>/*, we'll get a deadlock - read will wait for s_umount (in sget(), called by r_start()), while umount will wait in remove_proc_entry() for that read to finish, holding s_umount all along. Fortunately, the same change allows a much simpler race avoidance - all we need to do is remove the procfs entries in the very beginning of reiserfs ->kill_sb(); that'll guarantee that pointer to superblock will remain valid for the duration for procfs IO, so we don't need sget() to keep the sucker alive. As the matter of fact, we can get rid of the home-grown iterator completely, and use single_open() instead. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2013-08-05perf/x86: Fix intel QPI uncore event definitionsVince Weaver
John McCalpin reports that the "drs_data" and "ncb_data" QPI uncore events are missing the "extra bit" and always return zero values unless the bit is properly set. More details from him: According to the Xeon E5-2600 Product Family Uncore Performance Monitoring Guide, Table 2-94, about 1/2 of the QPI Link Layer events (including the ones that "perf" calls "drs_data" and "ncb_data") require that the "extra bit" be set. This was confusing for a while -- a note at the bottom of page 94 says that the "extra bit" is bit 16 of the control register. Unfortunately, Table 2-86 clearly says that bit 16 is reserved and must be zero. Looking around a bit, I found that bit 21 appears to be the correct "extra bit", and further investigation shows that "perf" actually agrees with me: [root@c560-003.stampede]# cat /sys/bus/event_source/devices/uncore_qpi_0/format/event config:0-7,21 So the command # perf -e "uncore_qpi_0/event=drs_data/" Is the same as # perf -e "uncore_qpi_0/event=0x02,umask=0x08/" While it should be # perf -e "uncore_qpi_0/event=0x102,umask=0x08/" I confirmed that this last version gives results that agree with the amount of data that I expected the STREAM benchmark to move across the QPI link in the second (cross-chip) test of the original script.

The mark argument is read only, so constify it. Also make dummy_mark in af_key const -- only used as dummy argument for this very function.

2013-08-04busy_poll: cleanup do-nothing placeholdersEliezer Tamir
When renaming ll_poll to busy poll, I introduced a typo in the name of the do-nothing placeholder for sk_busy_loop and called it sk_busy_poll. This broke compile when busy poll was not configured. Cong Wang submitted a patch to fixed that. This patch removes the now redundant, misspelled placeholder. Signed-off-by: Eliezer Tamir <eliezer.tamir@linux.intel.com> Signed-off-by: David S.

2013-08-04ACPI / video: improve quirk check in acpi_video_bqc_quirk()Felipe Contreras
If the _BCL package ordering is descending, the first level (br->levels[2]) is likely to be 0, and if the number of levels matches the number of steps, we might confuse a returned level to mean the index. For example: current_level = max_level = 100 test_level = 0 returned level = 100 In this case 100 means the level, not the index, and _BCM failed. Still, if the _BCL package ordering is descending, the index of level 0 is also 100, so we assume _BQC is indexed, when it's not. This causes all _BQC calls to return bogus values causing weird behavior from the user's perspective. For example: xbacklight -set 10; xbacklight -set 20; would flash to 90% and then slowly down to the desired level (20). The solution is simple; test anything other than the first level (e.g. 1).
