2015-02-11f2fs: use spinlock for segmap_lock instead of rwlockChao Yu
rwlock can provide better concurrency when there are much more readers than writers because readers can hold the rwlock simultaneously. But now, for segmap_lock rwlock in struct free_segmap_info, there is only one reader 'mount' from below call path: ->f2fs_fill_super ->build_segment_manager ->build_dirty_segmap ->init_dirty_segmap ->find_next_inuse read_lock ... read_unlock Now that our concurrency can not be improved since there is no other reader for this lock, we do not need to use rwlock_t type for segmap_lock, let's replace it with spinlock_t type.

This patch fixes the following test. This causes: attempt to access beyond end of device sdb2: rw=16384, want=14413962000, limit=16777216 The reason is: - f2fs_write_begin - f2fs_convert_inline_inode returns -ENOSPC - f2fs_write_failed - truncate_blocks - truncate_partial_data_page - find_data_page - get_dnode_of_data returns wrong data index retrieved from inline_data - f2fs_submit_page_bio(wrong data index) - submit_bio(wrong data index) Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

FAIL" The reason of this issue is: We will calculate current offset through left shifting page-offset with PAGE_CACHE_SHIFT bits, but our page-offset is a type of unsigned long, its size is 4 bytes in 32-bits machine. So if our page-offset is bigger than (1 << 32 / pagesize - 1), result of left shifting will overflow. Let's fix this issue by casting type of page-offset to type of current offset: loff_t.

2015-02-11f2fs: fix to use highmem for pages of newly created directoryChao Yu
In commit a78186ebe516 ("f2fs: use highmem for directory pages"), we have set __GFP_HIGHMEM into dir mapping's gfp flag in f2fs_iget, so high address memory could be used for these existing dir's page. But we forgot to set flag for newly created dir, due to this reason, our newly created dir pages could not be allocated from high address memory. Fix it.

2015-02-11f2fs: merge flags in struct f2fs_sb_infoChao Yu
Currently, there are several variables with Boolean type as below: struct f2fs_sb_info { ... int s_dirty; bool need_fsck; bool s_closing; ... bool por_doing; ... } For this there are some issues: 1. there are some space of f2fs_sb_info is wasted due to aligning after Boolean type variables by compiler. 2. if we continuously add new flag into f2fs_sb_info, structure will be messed up. So in this patch, we try to: 1. switch s_dirty to Boolean type variable since it has two status 0/1. 2. merge s_dirty/need_fsck/s_closing/por_doing variables into s_flag. 3. introduce an enum type which can indicate different states of sbi. 4. use new introduced universal interfaces is_sbi_flag_set/{set,clear}_sbi_flag to operate flags for sbi.

2015-02-12cpufreq: speedstep-smi: enable interrupts when waitingMikulas Patocka
On Dell Latitude C600 laptop with Pentium 3 850MHz processor, the speedstep-smi driver sometimes loads and sometimes doesn't load with "change to state X failed" message. The hardware sometimes refuses to change frequency and in this case, we need to retry later. I found out that we need to enable interrupts while waiting. When we enable interrupts, the hardware blockage that prevents frequency transition resolves and the transition is possible. With disabled interrupts, the blockage doesn't resolve (no matter how long do we wait). The exact reasons for this hardware behavior are unknown. This patch enables interrupts in the function speedstep_set_state that can be called with disabled interrupts. However, this function is called with disabled interrupts only from speedstep_get_freqs, so it shouldn't cause any problem.

2015-02-11cipso: don't use IPCB() to locate the CIPSO IP optionPaul Moore
Using the IPCB() macro to get the IPv4 options is convenient, but unfortunately NetLabel often needs to examine the CIPSO option outside of the scope of the IP layer in the stack. While historically IPCB() worked above the IP layer, due to the inclusion of the inet_skb_param struct at the head of the {tcp,udp}_skb_cb structs, recent commit 971f10ec ("tcp: better TCP_SKB_CB layout to reduce cache line misses") reordered the tcp_skb_cb struct and invalidated this IPCB() trick. This patch fixes the problem by creating a new function, cipso_v4_optptr(), which locates the CIPSO option inside the IP header without calling IPCB(). Unfortunately, this isn't as fast as a simple lookup so some additional tweaks were made to limit the use of this new function.

2015-02-11xilinx usb2 gadget: get rid of incredibly annoying compile warningLinus Torvalds
This one was driving me mad, with several lines of warnings during the allmodconfig build for a single bogus pointer cast. The warning was so verbose due to the indirect macro expansion explanation, and the whole thing was just for a debug printout. The bogus pointer-to-integer cast was pointless anyway, so just remove it, and use '%p' to show the pointer. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2015-02-11block: handle the null_mapped flag correctly in blk_rq_map_user_iovChristoph Hellwig
The tape drivers (and the sg driver in a special case that doesn't matter here) use the null_mapped flag to tell blk_rq_map_user to not copy around any data into or out of the bounce buffers. blk_rq_map_user_iov never got that treatment, which didn't matter until I refactored blk_rq_map_user to be implemented in terms of blk_rq_map_user_iov.
