For ACPI support of the HiSilicon LPC driver we depend on MFD_CORE config. Currently the HiSi LPC Kconfig entry does not define this dependency, so add it. The reason for depending on MFD_CORE in the driver is that we model the LPC host as an MFD, in that a platform device will be created for each device on the bus. We do this as we need to modify the resources of these derived platform devices, something which we should not do to the original devices created in the ACPI scan. Details in e0aa1563 ("HISI LPC: Add ACPI support").

f2fs specifies the __GFP_ZERO flag for allocating some of its pages. Unfortunately, the page cache also uses the mapping's GFP flags for allocating radix tree nodes. It always masked off the __GFP_HIGHMEM flag, and masks off __GFP_ZERO in some paths, but not all. That causes radix tree nodes to be allocated with a NULL list_head, which causes backtraces like: __list_del_entry+0x30/0xd0 list_lru_del+0xac/0x1ac page_cache_tree_insert+0xd8/0x110 The __GFP_DMA and __GFP_DMA32 flags would also be able to sneak through if they are ever used. Fix them all by using GFP_RECLAIM_MASK at the innermost location, and remove it from earlier in the callchain.

Commit 95846ecf ("pid: replace pid bitmap implementation with IDR API") changed last field of /proc/loadavg (last pid allocated) to be off by one: # unshare -p -f --mount-proc cat /proc/loadavg 0.00 0.00 0.00 1/60 2 <=== It should be 1 after first fork into pid namespace. This is formally a regression but given how useless this field is I don't think anyone is affected. Bug was found by /proc testsuite!

The autofs file system mkdir inode operation blindly sets the created directory mode to S_IFDIR | 0555, ingoring the passed in mode, which can cause selinux dac_override denials. But the function also checks if the caller is the daemon (as no-one else should be able to do anything here) so there's no point in not honouring the passed in mode, allowing the daemon to set appropriate mode when required.

The idea behind using kernel@pengutronix.de (i.e. the mail alias for the kernel people at Pengutronix) as email address was to have a backup when a given developer is on vacation or run over by a bus.

KASAN uses the __no_sanitize_address macro to disable instrumentation of particular functions. Right now it's defined only for GCC build, which causes false positives when clang is used. This patch adds a definition for clang. Note, that clang's revision 329612 or higher is required.

Some of the mport_dma_req structure members were initialized late inside the do_dma_request() function, just before submitting the request to the dma engine. But we have some error branches before that. In case of such an error, the code would return on the error path and trigger the calling of dma_req_free() with a req structure which is not completely initialized. This causes a NULL pointer dereference in dma_req_free(). This patch fixes these error branches by making sure that all necessary mport_dma_req structure members are initialized in rio_dma_transfer() immediately after the request structure gets allocated.

My testing for the latest kernel supporting thp migration showed an infinite loop in offlining the memory block that is filled with shmem thps. We can get out of the loop with a signal, but kernel should return with failure in this case. What happens in the loop is that scan_movable_pages() repeats returning the same pfn without any progress. That's because page migration always fails for shmem thps. In memory offline code, memory blocks containing unmovable pages should be prevented from being offline targets by has_unmovable_pages() inside start_isolate_page_range(). So it's possible to change migratability for non-anonymous thps to avoid the issue, but it introduces more complex and thp-specific handling in migration code, so it might not good. So this patch is suggesting to fix the issue by enabling thp migration for shmem thp. Both of anon/shmem thp are migratable so we don't need precheck about the type of thps.
