This came to light when calling memblock allocator from arc port (for copying flattended DT). If a "0" alignment is passed, the allocator round_up() call incorrectly rounds up the size to 0. round_up(num, alignto) => ((num - 1) | (alignto -1)) + 1 While the obvious allocation failure causes kernel to panic, it is better to warn the caller to fix the code. Tejun suggested that instead of BUG_ON(!align) - which might be ineffective due to pending console init and such, it is better to WARN_ON, and continue the boot with a reasonable default align. Caller passing @size need not be handled similarly as the subsequent panic will indicate that anyhow. Signed-off-by:

Paul E. McKenney authored
There is an ifdef in page_cache_get_speculative() that checks for !SMP and TREE_RCU, which has been an impossible combination since the advent of TINY_RCU. The ifdef enables a fastpath that is valid when preemption is disabled by rcu_read_lock() in UP systems, which is the case when TINY_RCU is enabled. This commit therefore adjusts the ifdef to generate the fastpath when TINY_RCU is enabled. Signed-off-by:

On large systems with a lot of memory, walking all RAM to determine page types may take a half second or even more. In non-blockable contexts, the page allocator will emit a page allocation failure warning unless __GFP_NOWARN is specified. In such contexts, irqs are typically disabled and such a lengthy delay may even result in NMI watchdog timeouts. To fix this, suppress the page walk in such contexts when printing the page allocation failure warning. Signed-off-by:

Use the events API to trace filemap loading and unloading of file pieces into the page cache. This patch aims at tracing the eviction reload cycle of executable and shared libraries pages in a memory constrained environment. The typical usage is to spot a specific device and inode (for example /lib/libc.so) to see the eviction cycles, and find out if frequently used code is rather spread across many pages (bad) or coallesced (good).

Currently page_action() does not check dirty flag to determine whether the error page is "clean mlocked/unevictable LRU" page. This doesn't cause any misjudgement because we do matching against "dirty mlocked/unevictable LRU" just before the check. But in order to make code consistent and/or to avoid potential regression, we had better check dirty flag explicitly. Signed-off-by:

The WARN_ON(1) in DEBUG_LOCKS_WARN_ON is surprisingly awkward to track down when it's hit, as it's usually buried in macros, causing multiple instances to land on the same line number. This patch makes it more useful by switching to: WARN(1, "DEBUG_LOCKS_WARN_ON(%s)", #c); so that the particular DEBUG_LOCKS_WARN_ON is more easily identified and grep'd for. For example: WARNING: at kernel/mutex.c:198 _mutex_lock_nested+0x31c/0x380() DEBUG_LOCKS_WARN_ON(l->magic != l) Signed-off-by:James Hogan <james.hogan@imgtec.com> Cc: Paul Gortmaker <paul.gortmaker@windriver.com> Cc: David Howells <dhowells@redhat.com> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by:

It can accidentally happen that the faulting insn (the exact instruction bytes) is repeated a little further on in the trace. This causes that same instruction to be tagged twice, see example below. What we want to do, however, is to track back from the end of the whole disassembly so many lines as the slice which starts with the faulting instruction is long. This leads us to the actual faulting instruction and *then* we tag it. While we're at it, we can drop the sed "g" flag because we address only this one line. Also, if we point to an instruction which changes decoding depending on the slice being objdumped, like a Jcc insn, for example, we do not even tag it as a faulting instruction because the instruction decode changes in the second slice but we use that second format as a regex on the fsrst disassembled buffer and more often than not that instruction doesn't match. Again, simply tag the line which is deduced from the original "<>" marking we've received from the kernel. This also solves the pathologic issue of multiple tagging like this: 29:* 0f 0b ud2 <-- trapping instruction 2b:* 0f 0b ud2 <-- trapping instruction 2d:* 0f 0b ud2 <-- trapping instruction Double tagging example: Code: 34 dd 40 30 ad 81 48 c7 c0 80 f6 00 00 48 8b 3c 30 48 01 c6 b8 ff ff ff ff 48 8d 57 f0 48 39 f7 74 2f 49 8b 4c 24 08 48 8b 47 f0 <48> 39 48 08 75 0e eb 2a 66 90 48 8b 40 f0 48 39 48 08 74 1e 48 All code ======== 0: 34 dd xor $0xdd,%al 2: 40 30 ad 81 48 c7 c0 xor %bpl,-0x3f38b77f(%rbp) 9: 80 f6 00 xor $0x0,%dh c: 00 48 8b add %cl,-0x75(%rax) f: 3c 30 cmp $0x30,%al 11: 48 01 c6 add %rax,%rsi 14: b8 ff ff ff ff mov $0xffffffff,%eax 19: 48 8d 57 f0 lea -0x10(%rdi),%rdx 1d: 48 39 f7 cmp %rsi,%rdi 20: 74 2f je 0x51 22: 49 8b 4c 24 08 mov 0x8(%r12),%rcx 27: 48 8b 47 f0 mov -0x10(%rdi),%rax 2b:* 48 39 48 08 cmp %rcx,0x8(%rax) <-- trapping instruction 2f: 75 0e jne 0x3f 31: eb 2a jmp 0x5d 33: 66 90 xchg %ax,%ax 35: 48 8b 40 f0 mov -0x10(%rax),%rax 39:* 48 39 48 08 cmp %rcx,0x8(%rax) <-- trapping instruction 3d: 74 1e je 0x5d 3f: 48 rex.W Signed-off-by:

task_get_live_kthread() looks confusing and unneeded. It does get_task_struct() but only kthread_stop() needs this, it can be called even if the calller doesn't have a reference when we know that this kthread can't exit until we do kthread_stop(). kthread_park() and kthread_unpark() do not need get_task_struct(), the callers already have the reference. And it can not help if we can race with the exiting kthread anyway, kthread_park() can hang forever in this case. Change kthread_park() and kthread_unpark() to use to_live_kthread(), change kthread_stop() to do get_task_struct() by hand and remove task_get_live_kthread(). Signed-off-by:

"k->vfork_done != NULL" with a barrier() after to_kthread(k) in task_get_live_kthread(k) looks unclear, and sub-optimal because we load ->vfork_done twice. All we need is to ensure that we do not return to_kthread(NULL). Add a new trivial helper which loads/checks ->vfork_done once, this also looks more understandable. Signed-off-by:

Pull pinctrl update from Linus Walleij: "These are the pinctrl changes for v3.10: - Patrice Chotard contributed a new configuration debugfs interface and reintroduced fine-grained locking into the core: instead of having a "big pinctrl lock" we have a per-controller lock and specialized locks for the global controller and pinctrl handle lists. - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and replaced them with pinctrl-single (which is also used by other SoCs) so we are gaining consolidation. The platform particulars now come in through the device tree. - Haoijan also added support for generic pin config into the pinctrl-single driver which is another big consolidation win. - Finally also GPIO ranges are now supported by the pinctrl-single driver. - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing more of the older Samsung platforms under the pinctrl umbrella and out of arch/arm. - Maxime Ripard contributed new Allwinner A10/A13 drivers. - Sachin Kamat, Wei Yongjun and Axel Lin did a lot of cleanups." * tag 'pinctrl-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (66 commits) pinctrl: move subsystem mutex to pinctrl_dev struct pinctrl/pinconfig: fix misplaced goto pinctrl: s3c64xx: Fix build error caused by undefined chained_irq_enter pinctrl/pinconfig: add debug interface pinctrl: abx500: fix issue when no pdata pinctrl: pinctrl-single: add missing double quote pinctrl: sunxi: Rename wemac functions to emac pinctrl: exynos5440: add gpio interrupt support pinctrl: exynos5440: fix probe failure due to missing pin-list in config nodes pinctrl: ab8505: Staticize some symbols pinctrl: ab8540: Staticize some symbols pinctrl: ab9540: Staticize some symbols pinctrl: ab8500: Staticize some symbols pinctrl: abx500: Staticize some symbols pinctrl: Add pinctrl-s3c64xx driver pinctrl: samsung: Handle banks with two configuration registers pinctrl: samsung: Remove hardcoded register offsets pinctrl: samsung: Split pin bank description into two structures pinctrl: samsung: Include pinctrl-exynos driver data conditionally pinctrl: samsung: Protect bank registers with a spinlock ... -
