2019-12-17mm: vmscan: protect shrinker idr replace with CONFIG_MEMCGYang Shi
Since commit 0a432dcbeb32 ("mm: shrinker: make shrinker not depend on memcg kmem"), shrinkers' idr is protected by CONFIG_MEMCG instead of CONFIG_MEMCG_KMEM, so it makes no sense to protect shrinker idr replace with CONFIG_MEMCG_KMEM. And in the CONFIG_MEMCG && CONFIG_SLOB case, shrinker_idr contains only shrinker, and it is deferred_split_shrinker. But it is never actually called, since idr_replace() is never compiled due to the wrong #ifdef. The deferred_split_shrinker all the time is staying in half-registered state, and it's never called for subordinate mem cgroups.

2019-12-17kasan: don't assume percpu shadow allocations will succeedDaniel Axtens
syzkaller and the fault injector showed that I was wrong to assume that we could ignore percpu shadow allocation failures. Handle failures properly. Merge all the allocated areas back into the free list and release the shadow, then clean up and return NULL. The shadow is released unconditionally, which relies upon the fact that the release function is able to tolerate pages not being present. Also clean up shadows in the recovery path - currently they are not released, which leaks a bit of memory.

2019-12-17kasan: use apply_to_existing_page_range() for releasing vmalloc shadowDaniel Axtens
kasan_release_vmalloc uses apply_to_page_range to release vmalloc shadow. Unfortunately, apply_to_page_range can allocate memory to fill in page table entries, which is not what we want.

2019-12-17mm/memory.c: add apply_to_existing_page_range() helperDaniel Axtens
apply_to_page_range() takes an address range, and if any parts of it are not covered by the existing page table hierarchy, it allocates memory to fill them in. In some use cases, this is not what we want - we want to be able to operate exclusively on PTEs that are already in the tables. Add apply_to_existing_page_range() for this. Adjust the walker functions for apply_to_page_range to take 'create', which switches them between the old and new modes. This will be used in KASAN vmalloc.

2019-12-17kasan: fix crashes on access to memory mapped by vm_map_ram()Andrey Ryabinin
With CONFIG_KASAN_VMALLOC=y any use of memory obtained via vm_map_ram() will crash because there is no shadow backing that memory. Instead of sprinkling additional kasan_populate_vmalloc() calls all over the vmalloc code, move it into alloc_vmap_area(). This will fix vm_map_ram() and simplify the code a bit.

2019-12-17tpm: fix invalid locking in NONBLOCKING modeTadeusz Struk
When an application sends TPM commands in NONBLOCKING mode the driver holds chip->tpm_mutex returning from write(), which triggers: "WARNING: lock held when returning to user space". To fix this issue the driver needs to release the mutex before returning and acquire it again in tpm_dev_async_work() before sending the command.

2019-12-17security: keys: trusted: fix lost handle flushJames Bottomley
The original code, before it was moved into security/keys/trusted-keys had a flush after the blob unseal. Without that flush, the volatile handles increase in the TPM until it becomes unusable and the system either has to be rebooted or the TPM volatile area manually flushed. Fix by adding back the lost flush, which we now have to export because of the relocation of the trusted key code may cause the consumer to be modular.

commit 781fa0a95424 ("ARM: bcm: Add support for BCM2711 SoC") breaks boot of many other platforms (e.g. OMAP or i.MX6) if CONFIG_ARCH_BCM2835 is enabled in addition to some multiplatform config (e.g. omap2plus_defconfig). The symptom is that the OMAP based board does not show any activity beyond "Starting Kernel ..." even with earlycon. Reverting the mentioned commit makes it work again. The real fix is to add the missing NULL sentinel to the bcm2711_compat[] variable-length array.
