There are some places where we do like: pte = pte_map(); do { (do break in some conditions) } while (pte++, ...); pte_unmap(pte - 1); But if the loop breaks at the first loop, pte_unmap() unmaps invalid pte.

I have learned that the 6730b and 6730s have different accelerometer orientation, and have modified the driver accordingly (diff attached), while dropping the wild guess for AMD based 6735 having the same orientation as Intel based 6730 (this is not true for any other related series/family, thus is not probable for 673x).

In the case where cpuidle_idle_call() returns before changing state due to a need_resched(), it was returning with IRQs disabled. The idle path assumes that the platform specific idle code returns with interrupts enabled (although this too is undocumented AFAICT) and on ARM we have a WARN_ON(!(irqs_disabled()) when returning from the idle loop, so the user-visible effects were only a warning since interrupts were eventually re-enabled later. On x86, this same problem exists, but there is no WARN_ON() to detect it. As on ARM, the interrupts are eventually re-enabled, so I'm not sure of any actual bugs triggered by this. It's primarily a correctness/consistency fix. This patch ensures IRQs are (re)enabled before returning. Reported-by:

In the following code, union thread_union init_thread_union __attribute__((__section__(".data.init_task"))) = { INIT_THREAD_INFO(init_task) }; There is a non-conforming declaration. It should really be like the following, union thread_union init_thread_union __attribute__((__section__(".data.init_task"))) = { INIT_THREAD_INFO(init_task) }; However, checkpatch doesn't catch this right now because it doesn't correctly evaluate the "__attribute__". It is not at all clear that we care what preceeds an assignment style attribute when we find the open brace. Relax the test so we do not need to check the __attribute__. Reported-by: -

The macro concatenation (##) sequence can cause false errors when checking macro's. Checkpatch doesn't currently know about the operator. For example this line, + entry = (struct ftrace_raw_##call *)raw_data; \ is correct but it produces the following error, ERROR: need consistent spacing around '*' (ctx:WxB) + entry = (struct ftrace_raw_##call *)raw_data;\ ^ The line above doesn't have any spacing problems, and if you remove the macro concatenation sequence checkpatch doesn't give any errors. Extend identifier handling to include ## concatenation within the definition of an identifier. Reported-by: -

The i5400 EDAC driver has several bugs with chip-select row computation which most likely lead to bugs in detailed error reporting. Attempts to contact the authors have gone mostly unanswered so I am presenting my diff here. I do not subscribe to lkml and would appreciate being kept in the cc. The most egregious problem was miscalculating the addresses of MTR registers after register 0 by assuming they are 32bit rather than 16. This caused the driver to miss half of the memories. Most motherboards tend to have only 8 dimm slots and not 16, so this may not have been noticed before. Further, the row calculations multiplied the number of dimms several times, ultimately ending up with a maximum row of 32. The chipset only supports 4 dimms in each of 4 channels, so csrow could not be higher than 4 unless you use a row per-rank with dual-rank dimms. I opted to eliminate this behavior as it is confusing to the user and the error reporting works by slot and not rank. This gives a much clearer view of memory by slot and channel in /sys.

The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the former has __devinit, so the latter cannot use __devexit. Otherwise we hit the section mismatch warning: WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch in reference from the function _gpio_twl4030_probe() to the function .devexit.text:_gpio_twl4030_remove() The function __devinit _gpio_twl4030_probe() references a function __devexit _gpio_twl4030_remove(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of _gpio_twl4030_remove() so it may be used outside an exit section. Signed-off-by:

Johannes Weiner authored
Isolators putting a page back to the LRU do not hold the page lock, and if the page is mlocked, another thread might munlock it concurrently. Expecting this, the putback code re-checks the evictability of a page when it just moved it to the unevictable list in order to correct its decision. The problem, however, is that ordering is not garuanteed between setting PG_lru when moving the page to the list and checking PG_mlocked afterwards: #0: #1 spin_lock() if (TestClearPageMlocked()) if (PageLRU()) move to evictable list SetPageLRU() spin_unlock() if (!PageMlocked()) move to evictable list The PageMlocked() check may get reordered before SetPageLRU() in #0, resulting in #0 not moving the still mlocked page, and in #1 failing to isolate and move the page as well. The page is now stranded on the unevictable list. The race condition is very unlikely. The consequence currently is one page falling off the reclaim grid and eventually getting freed with PG_unevictable set, which triggers a warning in the page allocator. TestClearPageMlocked() in #1 already provides full memory barrier semantics. This patch adds an explicit full barrier to force ordering between SetPageLRU() and PageMlocked() so that either one of the competitors rescues the page. Signed-off-by:

A particular fsfuzzer run caused an hfs file system to crash on mount. This is due to a corrupted MDB extent record causing a miscalculation of HFS_I(inode)->first_blocks for the extent tree. If the extent records are zereod out, it won't trigger the first_blocks special case. Instead it falls through to the extent code which we're still in the middle of initializing. This patch catches the 0 size extent records, reports the corruption, and fails the mount. Reported-by:

As found in <http://bugs.debian.org/550010>, hfsplus is using type u32 rather than sector_t for some sector number calculations. In particular, hfsplus_get_block() does: u32 ablock, dblock, mask; ... map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask)); I am not confident that I can find and fix all cases where a sector number may be truncated. For now, avoid data loss by refusing to mount HFS+ volumes with more than 2^32 sectors (2TB). [akpm@linux-foundation.org: fix 32 and 64-bit issues] Signed-off-by:
