We seem to have accumulated a bunch of checkpatch warnings, with mainly overlong lines and two unnecessary allocation error messages. Most were introduced with the recent multi-controller-support but some were quite a bit older. Signed-off-by: Heiko Stuebner <heiko@sntech.de>

The internal clk header did contain a comment indicating that some of the defined registers were shared over multiple clock controller variants. In recent times, it was simply extended all the time and stopped providing any meaningful information, so drop it and it's overlong line. Signed-off-by: Heiko Stuebner <heiko@sntech.de>

We allow overlong lines in the array portitions describing the clock trees to ease readability by having each element always at the same position. But the rest of the code should honor the 80 char limit. Fix the newly added rk3399 clock code to respect that. Signed-off-by: Heiko Stuebner <heiko@sntech.de>

Thers are only two parent PLLs that APLL and GPLL for core on the previous SoCs (RK3066/RK3188/RK3288/RK3368). Hence, we set fixed GPLL as alternate parent when core is switching freq. Since RK3399 big.LITTLE architecture, we need to select and adapt more PLLs (ALPLL/ABPLL/DPLL/GPLL) sources.

Commit 0b81d077 ("fs crypto: move per-file encryption from f2fs tree to fs/crypto") moved the f2fs crypto files to fs/crypto/ and renamed the symbol prefixes from "f2fs_" to "fscrypt_" (and from "F2FS_" to just "FS" for preprocessor symbols). Because of the symbol renaming, it's a bit hard to see it as a file move: use git show -M30 0b81d077 to lower the rename detection to just 30% similarity and make git show the files as renamed (the header file won't be shown as a rename even then - since all it contains is symbol definitions, it looks almost completely different). Even with the renames showing as renames, the diffs are not all that easy to read, since so much is just the renames. But Eric Biggers noticed that it's not just all renames: the initialization of the xts_tweak had been broken too, using the inode number rather than the page offset. That's not right - it makes the xfs_tweak the same for all pages of each inode. It _might_ make sense to make the xfs_tweak contain both the offset _and_ the inode number, but not just the inode number.

* switch orangefs_remount() to taking ORANGEFS_SB(sb) instead of sb * remove from the list _before_ orangefs_unmount() - request_mutex in the latter will make sure that nothing observed in the loop in ORANGEFS_DEV_REMOUNT_ALL handling will get freed until the end of loop * on removal, keep the forward pointer and zero the back one. That way we can drop and regain the spinlock in the loop body (again, ORANGEFS_DEV_REMOUNT_ALL one) and still be able to get to the rest of the list.

If - generic_file_read_iter() gets called with a zero read length, - the read offset is at a page boundary, - IOCB_DIRECT is not set - and the page in question hasn't made it into the page cache yet, then do_generic_file_read() will trigger a readahead with a req_size hint of zero. Since roundup_pow_of_two(0) is undefined, UBSAN reports UBSAN: Undefined behaviour in include/linux/log2.h:63:13 shift exponent 64 is too large for 64-bit type 'long unsigned int' CPU: 3 PID: 1017 Comm: sa1 Tainted: G L 4.5.0-next-20160318+ #14 [...] Call Trace: [...] [<ffffffff813ef61a>] ondemand_readahead+0x3aa/0x3d0 [<ffffffff813ef61a>] ? ondemand_readahead+0x3aa/0x3d0 [<ffffffff813c73bd>] ? find_get_entry+0x2d/0x210 [<ffffffff813ef9c3>] page_cache_sync_readahead+0x63/0xa0 [<ffffffff813cc04d>] do_generic_file_read+0x80d/0xf90 [<ffffffff813cc955>] generic_file_read_iter+0x185/0x420 [...] [<ffffffff81510b06>] __vfs_read+0x256/0x3d0 [...] when get_init_ra_size() gets called from ondemand_readahead(). The net effect is that the initial readahead size is arch dependent for requested read lengths of zero: for example, since 1UL << (sizeof(unsigned long) * 8) evaluates to 1 on x86 while its result is 0 on ARMv7, the initial readahead size becomes 4 on the former and 0 on the latter. What's more, whether or not the file access timestamp is updated for zero length reads is decided differently for the two cases of IOCB_DIRECT being set or cleared: in the first case, generic_file_read_iter() explicitly skips updating that timestamp while in the latter case, it is always updated through the call to do_generic_file_read(). According to POSIX, zero length reads "do not modify the last data access timestamp" and thus, the IOCB_DIRECT behaviour is POSIXly correct. Let generic_file_read_iter() unconditionally check the requested read length at its entry and return immediately with success if it is zero.
