[PATCH] powerpc/fsl_booke/32: fix build with CONFIG_RANDOMIZE_BASE

by Arseny Solokha

Building the current 5.8 kernel for a e500 machine with CONFIG_RANDOMIZE_BASE set yields the following failure: arch/powerpc/mm/nohash/kaslr_booke.c: In function 'kaslr_early_init': arch/powerpc/mm/nohash/kaslr_booke.c:387:2: error: implicit declaration of function 'flush_icache_range'; did you mean 'flush_tlb_range'? [-Werror=implicit-function-declaration] Indeed, including asm/cacheflush.h into kaslr_booke.c fixes the build. The issue dates back to the introduction of that file and probably went unnoticed because there's no in-tree defconfig with CONFIG_RANDOMIZE_BASE set.

[patch 31/32] mm/memory_hotplug.c: fix false softlockup during pfn range removal

by Andrew Morton

From: Ben Widawsky <ben.widawsky(a)intel.com> Subject: mm/memory_hotplug.c: fix false softlockup during pfn range removal When working with very large nodes, poisoning the struct pages (for which there will be very many) can take a very long time. If the system is using voluntary preemptions, the software watchdog will not be able to detect forward progress. This patch addresses this issue by offering to give up time like __remove_pages() does. This behavior was introduced in v5.6 with: commit d33695b16a9f ("mm/memory_hotplug: poison memmap in remove_pfn_range_from_zone()") Alternately, init_page_poison could do this cond_resched(), but it seems to me that the caller of init_page_poison() is what actually knows whether or not it should relax its own priority. Based on Dan's notes, I think this is perfectly safe: commit f931ab479dd2 ("mm: fix devm_memremap_pages crash, use mem_hotplug_{begin, done}") Aside from fixing the lockup, it is also a friendlier thing to do on lower core systems that might wipe out large chunks of hotplug memory (probably not a very common case). Fixes this kind of splat: [ 352.142079] watchdog: BUG: soft lockup - CPU#46 stuck for 22s!

[patch 12/32] mm/slab: use memzero_explicit() in kzfree()

by Andrew Morton

From: Waiman Long <longman(a)redhat.com> Subject: mm/slab: use memzero_explicit() in kzfree() The kzfree() function is normally used to clear some sensitive information, like encryption keys, in the buffer before freeing it back to the pool. Memset() is currently used for buffer clearing. However unlikely, there is still a non-zero probability that the compiler may choose to optimize away the memory clearing especially if LTO is being used in the future. To make sure that this optimization will never happen, memzero_explicit(), which is introduced in v3.18, is now used in kzfree() to future-proof it.

[patch 11/32] mm, slab: fix sign conversion problem in memcg_uncharge_slab()

by Andrew Morton

From: Waiman Long <longman(a)redhat.com> Subject: mm, slab: fix sign conversion problem in memcg_uncharge_slab() It was found that running the LTP test on a PowerPC system could produce erroneous values in /proc/meminfo, like: MemTotal: 531915072 kB MemFree: 507962176 kB MemAvailable: 1100020596352 kB Using bisection, the problem is tracked down to commit 9c315e4d7d8c ("mm: memcg/slab: cache page number in memcg_(un)charge_slab()"). In memcg_uncharge_slab() with a "int order" argument: unsigned int nr_pages = 1 << order; : mod_lruvec_state(lruvec, cache_vmstat_idx(s), -nr_pages); The mod_lruvec_state() function will eventually call the __mod_zone_page_state() which accepts a long argument. Depending on the compiler and how inlining is done, "-nr_pages" may be treated as a negative number or a very large positive number. Apparently, it was treated as a large positive number in that PowerPC system leading to incorrect stat counts. This problem hasn't been seen in x86-64 yet, perhaps the gcc compiler there has some slight difference in behavior. It is fixed by making nr_pages a signed value. For consistency, a similar change is applied to memcg_charge_slab() as well.
