Add support for RTC of Exynos3250 SoC. The Exynos3250 needs source clock(32.768KHz) for RTC block. If source clock of RTC is registerd on clock list of common clk framework, Exynos RTC drvier have to control this clock. Clock list for s3c-rtc device: - rtc : CLK_RTC of CLK_GATE_IP_PERIR is gate clock for RTC. - rtc_src : XrtcXTI is 32.768.kHz source clock for RTC. (XRTCXTI: Specifies a clock from 32.768 kHz crystal pad with XRTCXTI and XRTCXTO pins. RTC uses this clock as the source of a real-time clock.) Signed-off-by:

If rcu-walk mode we don't *have* to return -EISDIR for non-mount-traps as we will simply drop into REF-walk and handling DCACHE_NEED_AUTOMOUNT dentrys the slow way. But it is better if we do when possible. In 'oz_mode', use the same condition as ref-walk: if not a mountpoint, then it must be -EISDIR. In regular mode there are most tests needed. Most of them can be performed without taking any spinlocks. If we find a directory that isn't obviously empty, and isn't mounted on, we need to call 'simple_empty()' which does take a spinlock. If this turned out to hurt performance, some other approach could be found to signal when a directory is known to be empty. Signed-off-by:

->fs_lock protects AUTOFS_INF_EXPIRING. We need to be sure that once the flag is set, no new references beneath the dentry are taken. So rcu-walk currently needs to take fs_lock before checking the flag. This hurts performance. Change the expiry to a two-stage process. First set AUTOFS_INF_NO_RCU which forces any path walk into ref-walk mode, then drop the lock and call synchronize_rcu(). Once that returns we can be sure no rcu-walk is active beneath the dentry and we can check reference counts again. Now during an RCU-walk we can test AUTOFS_INF_EXPIRING without taking the lock as along as we test AUTOFS_INF_NO_RCU too. If either are set, we must abort the RCU-walk If neither are set, we know that refcounts will be tested again after we finish the RCU-walk so we are safe to continue. ->fs_lock is still taken in d_manage() to check for a non-trap directory. That will be resolved in the next patch. Signed-off-by:

This series teaches autofs about RCU-walk so that we don't drop straight into REF-walk when we hit an autofs directory, and so that we avoid spinlocks as much as possible when performing an RCU-walk. This is needed so that the benefits of the recent NFS support for RCU-walk are fully available when NFS filesystems are automounted. Patches have been carefully reviewed and tested both with test suites and in production - thanks a lot to Ian Kent for his support there. This patch (of 6): Any attempt to look up a pathname that passes though an autofs4 mount is currently forced out of RCU-walk into REF-walk. This can significantly hurt performance of many-thread work loads on many-core systems, especially if the automounted filesystem supports RCU-walk but doesn't get to benefit from it. So if autofs4_d_manage is called with rcu_walk set, only fail with -ECHILD if it is necessary to wait longer than a spinlock. Signed-off-by:

gcc-4.9 on ARM gives us a mysterious warning about the binfmt_misc parse_command function: fs/binfmt_misc.c: In function 'parse_command.part.3': fs/binfmt_misc.c:405:7: warning: array subscript is above array bounds [-Warray-bounds] I've managed to trace this back to the ARM implementation of memset, which is called from copy_from_user in case of a fault and which does #define memset(p,v,n) \ ({ \ void *__p = (p); size_t __n = n; \ if ((__n) != 0) { \ if (__builtin_constant_p((v)) && (v) == 0) \ __memzero((__p),(__n)); \ else \ memset((__p),(v),(__n)); \ } \ (__p); \ }) Apparently gcc gets confused by the check for "size != 0" and believes that the size might be zero when it gets to the line that does "if (s[count-1] == '\n')", so it would access data outside of the array. gcc is clearly wrong here, since this condition was already checked earlier in the function and the 'size' value can not change in the meantime. Fortunately, we can work around it and get rid of the warning by rearranging the function to check for zero size after doing the copy_from_user. It is still safe to pass a zero size into copy_from_user, so it does not cause any side effects. Signed-off-by:

The current code places a 256 byte limit on the registration format. This ends up being fairly limited when you try to do matching against a binary format like ELF: - the magic & mask formats cannot have any embedded NUL chars (string_unescape_inplace halts at the first NUL) - each escape sequence quadruples the size: \x00 is needed for NUL - trying to match bytes at the start of the file as well as further on leads to a lot of \x00 sequences in the mask - magic & mask have to be the same length (when decoded) - still need bytes for the other fields - impossible! Let's look at a concrete (and common) example: using QEMU to run MIPS ELFs. The name field uses 11 bytes "qemu-mipsel". The interp uses 20 bytes "/usr/bin/qemu-mipsel". The type & flags takes up 4 bytes. We need 7 bytes for the delimiter (usually ":"). We can skip offset. So already we're down to 107 bytes to use with the magic/mask instead of the real limit of 128 (BINPRM_BUF_SIZE). If people use shell code to register (which they do the majority of the time), they're down to ~26 possible bytes since the escape sequence must be \x##. The ELF format looks like (both 32 & 64 bit): e_ident: 16 bytes e_type: 2 bytes e_machine: 2 bytes Those 20 bytes are enough for most architectures because they have so few formats in the first place, thus they can be uniquely identified. That also means for shell users, since 20 is smaller than 26, they can sanely register a handler. But for some targets (like MIPS), we need to poke further. The ELF fields continue on: e_entry: 4 or 8 bytes e_phoff: 4 or 8 bytes e_shoff: 4 or 8 bytes e_flags: 4 bytes We only care about e_flags here as that includes the bits to identify whether the ELF is O32/N32/N64. But now we have to consume another 16 bytes (for 32 bit ELFs) or 28 bytes (for 64 bit ELFs) just to match the flags. If every byte is escaped, we send 288 more bytes to the kernel ((20 {e_ident,e_type,e_machine} + 12 {e_entry,e_phoff,e_shoff} + 4 {e_flags}) * 2 {mask,magic} * 4 {escape}) and we've clearly blown our budget. Even if we try to be clever and do the decoding ourselves (rather than relying on the kernel to process \x##), we still can't hit the mark -- string_unescape_inplace treats mask & magic as C strings so NUL cannot be embedded. That leaves us with having to pass \x00 for the 12/24 entry/phoff/shoff bytes (as those will be completely random addresses), and that is a minimum requirement of 48/96 bytes for the mask alone. Add up the rest and we blow through it (this is for 64 bit ELFs): magic: 20 {e_ident,e_type,e_machine} + 24 {e_entry,e_phoff,e_shoff} + 4 {e_flags} = 48 # ^^ See note below. mask: 20 {e_ident,e_type,e_machine} + 96 {e_entry,e_phoff,e_shoff} + 4 {e_flags} = 120 Remember above we had 107 left over, and now we're at 168. This is of course the *best* case scenario -- you'll also want to have NUL bytes in the magic & mask too to match literal zeros. Note: the reason we can use 24 in the magic is that we can work off of the fact that for bytes the mask would clobber, we can stuff any value into magic that we want. So when mask is \x00, we don't need the magic to also be \x00, it can be an unescaped raw byte like '!'. This lets us handle more formats (barely) under the current 256 limit, but that's a pretty tall hoop to force people to jump through. With all that said, let's bump the limit from 256 bytes to 1920. This way we support escaping every byte of the mask & magic field (which is 1024 bytes by themselves -- 128 * 4 * 2), and we leave plenty of room for other fields. Like long paths to the interpreter (when you have source in your /really/long/homedir/qemu/foo). Since the current code stuffs more than one structure into the same buffer, we leave a bit of space to easily round up to 2k. 1920 is just as arbitrary as 256 ;). Signed-off-by:

The "_MODULE" suffix is reserved for tristates compiled as loadable kernel modules (LKM). The "TEST_MODULE" feature thereby violates this convention. The feature is used to compile the lib/test_module.c kernel module. Sadly this convention is not made explicit, but the Kconfig code documents it. The following code (./scripts/kconfig/confdata.c) is used to generate the autoconf.h header file during the build process. When a feature is selected as a kernel module ('m'), it is suffixed with "_MODULE" to indicate it. switch (*value) { case 'n': break; case 'm': suffix = "_MODULE"; /* fall through */ This causes problems for static code analysis, which assumes a consistent use of the "_MODULE" suffix. This patch renames the feature and its reference in a Makefile to "TEST_LKM", which still expresses the test of a LKM. Signed-off-by:

The prio_heap code is unused since commit 889ed9ce ("cgroup: remove css_scan_tasks()"). It should be compiled out to shrink the binary kernel size which can be done via introducing CONFIG_PRIO_HEAD or by removing the code. We can simply recover the code from git when needed, so it would be better to remove it IMO. Signed-off-by:

Inspired by some recent cleanups in MAINTAINERS the following files (F:) cannot be found any more in the tree: * arch/arm/mach-s5pv210/mach-aquila.c * arch/arm/mach-s5pv210/mach-goni.c Those two got removed in commit 28c8331d ("ARM: S5PV210: Remove support for board files"). Cc: Tomasz Figa <t.figa@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> * drivers/rtc/rtc-sec.c A MAINTAINERS fix was attempted in November 2012, but dismissed as rtc-sec.c was still being worked on. Alas, it's still not there.

Commit 458df9fd ("printk: remove separate printk_sched buffers and use printk buf instead") hardcodes printk_deferred() to KERN_WARNING and inserts the string "[sched_delayed] " before the actual message. However it doesn't take into account the KERN_* prefix of the message, that now ends up in the middle of the output: [sched_delayed] ^a4CE: hpet increased min_delta_ns to 20115 nsec Fix this by just getting rid of the "[sched_delayed] " scnprintf(). The prefix is useless since 458df9fd anyway since from that moment printk_deferred() inserts the message into the kernel printk buffer immediately. So if the message eventually gets printed to console, it is printed in the correct order with other messages and there's no need for any special prefix. And if the kernel crashes before the message makes it to console, then prefix in the printk buffer doesn't make the situation any better. Link: http://lkml.org/lkml/2014/9/14/4Signed-off-by:
