2018-09-28rtc: ds1685: drop RTC_DS1685_PROC_REGSAlexandre Belloni2-72/+0
/proc is not the correct ABI to display debugging info. Remove RTC_DS1685_PROC_REGS as the driver hasn't seen any real development since it was included. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

On m41txx you can enable open-drain OUT pin to check if offset is ok. Enabling OUT pin with frequency_test_enable attribute, OUT pin will tick 512 times faster than 1s tick base.

2018-09-11mfd: menelaus: Fix possible race condition and leakAlexandre Belloni1-4/+9
The IRQ work is added before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc before calling menelaus_add_irq_work. Also, this solves a possible leak as the RTC is never released.

2018-08-28rtc: sun6i: Use struct_size() in kzalloc()Gustavo A. R. Silva1-2/+1
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); Signed-off-by: Gustavo A.

The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax.

2018-08-25mm/cow: don't bother write protecting already write-protected pagesLinus Torvalds1-1/+1
This is not normally noticeable, but repeated forks are unnecessarily expensive because they repeatedly dirty the parent page tables during the page table copy operation. It's trivial to just avoid write protecting the page table entry if it was already not writable. This patch was inspired by https://bugzilla.kernel.org/show_bug.cgi?id=200447 which points to an ancient "waste time re-doing fork" issue in the presence of lots of signals. That bug was fixed by Eric Biederman's signal handling series culminating in commit c3ad2c3b02e9 ("signal: Don't restart fork when signals come in"), but the unnecessary work for repeated forks is still work just fixing, particularly since the fix is trivial.

2018-08-25hpfs: remove unnecessary checks on the value of r when assigning error codeColin Ian King1-1/+1
At the point where r is being checked for different values, r is always going to be equal to 2 as the previous if statements jump to end or end1 if r is not 2. Hence the assignment to err can be simplified to just err an assignment without any checks on the value or r.

Thanks for your work in this area. I still remember the first linux storage summit we did in Vancouver 2001, Tejun was invited to talk about his libata error handling work. Before that, it was basically a crap shoot if we recovered properly or not... A lot of water has flown under the bridge since then! Here's an "official" patch. Linus, can you apply it?
