bison/flex is now needed always for building for kconfig. Some build dependencies depend on kernel configuration, enable them as needed: - libelf-dev when UNWINDER_ORC is set - libssl-dev for SYSTEM_TRUSTED_KEYRING Since the libssl-dev is needed for extract_cert binary, denote with :native to install the libssl-dev for the build machines architecture, rather than for the architecture of the kernel being built.

The only detail worth noting, outside the summary below, is that the "libnvdimm-start-pad" topic has been truncated to just cleanups and small fixes.

Pull vfs mount infrastructure updates from Al Viro: "The rest of core infrastructure; no new syscalls in that pile, but the old parts are switched to new infrastructure. At that point conversions of individual filesystems can happen independently; some are done here (afs, cgroup, procfs, etc.), there's also a large series outside of that pile dealing with NFS (quite a bit of option-parsing stuff is getting used there - it's one of the most convoluted filesystems in terms of mount-related logics), but NFS bits are the next cycle fodder. It got seriously simplified since the last cycle; documentation is probably the weakest bit at the moment - I considered dropping the commit introducing Documentation/filesystems/mount_api.txt (cutting the size increase by quarter ;-), but decided that it would be better to fix it up after -rc1 instead. That pile allows to do followup work in independent branches, which should make life much easier for the next cycle. fs/super.c size increase is unpleasant; there's a followup series that allows to shrink it considerably, but I decided to leave that until the next cycle" * 'work.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (41 commits) afs: Use fs_context to pass parameters over automount afs: Add fs_context support vfs: Add some logging to the core users of the fs_context log vfs: Implement logging through fs_context vfs: Provide documentation for new mount API vfs: Remove kern_mount_data() hugetlbfs: Convert to fs_context cpuset: Use fs_context kernfs, sysfs, cgroup, intel_rdt: Support fs_context cgroup: store a reference to cgroup_ns into cgroup_fs_context cgroup1_get_tree(): separate "get cgroup_root to use" into a separate helper cgroup_do_mount(): massage calling conventions cgroup: stash cgroup_root reference into cgroup_fs_context cgroup2: switch to option-by-option parsing cgroup1: switch to option-by-option parsing cgroup: take options parsing into ->parse_monolithic() cgroup: fold cgroup1_mount() into cgroup1_get_tree() cgroup: start switching to fs_context ipc: Convert mqueue fs to fs_context proc: Add fs_context support to procfs ...

Very simple radix tree implementation that supports storing arbitrary size entries, up to PAGE_SIZE - upcoming patches will convert existing flex_array users to genradixes. The new genradix code has a much simpler API and implementation, and doesn't have a hard limit on the number of elements like flex_array does.

Patch series "generic radix trees; drop flex arrays". This patch (of 7): There was no real need for this code to be using flexarrays, it's just implementing a hash table - ideally it would be using rhashtables, but that conversion would be significantly more complicated.

The allocated region is registered with kmemleak, but it is then removed from memblock using memblock_remove() that is not kmemleak-aware. Replacing memblock_phys_alloc_range() with memblock_find_in_range() makes sure that the allocated memory is not added to kmemleak and then memblock_remove()'ing this memory is safe. As a bonus, since memblock_find_in_range() ensures the allocation in the specified range, the bounds check can be removed.

__next_mem_range() and __next_mem_range_rev() duplicate the code that checks whether a region should be skipped because of node or flags incompatibility. Split this code into a helper function. Link: http://lkml.kernel.org/r/1549455025-17706-3-git-send-email-rppt@linux.ibm.comSigned-off-by:

The memblock API provides dedicated helpers to set or clear a flag on a memory region, e.g. memblock_{mark,clear}_hotplug(). The memblock_{set,clear}_region_flags() functions are used only by the memblock internal function that adjusts the region flags. Drop these functions and use open-coded implementation instead.

As all the memblock allocation functions return NULL in case of error rather than panic(), the duplicates with _nopanic suffix can be removed. Link: http://lkml.kernel.org/r/1548057848-15136-22-git-send-email-rppt@linux.ibm.comSigned-off-by:

As all the memblock_alloc*() users are now checking the return value and panic() in case of error, the panic() call can be removed from the core memblock allocator, namely memblock_alloc_try_nid(). Link: http://lkml.kernel.org/r/1548057848-15136-21-git-send-email-rppt@linux.ibm.comSigned-off-by:

Add check for the return value of memblock_alloc*() functions and call panic() in case of error. The panic message repeats the one used by panicing memblock allocators with adjustment of parameters to include only relevant ones. The replacement was mostly automated with semantic patches like the one below with manual massaging of format strings. @@ expression ptr, size, align; @@ ptr = memblock_alloc(size, align); + if (!ptr) + panic("%s: Failed to allocate %lu bytes align=0x%lx\n", __func__, size, align); [anders.roxell@linaro.org: use '%pa' with 'phys_addr_t' type] Link: http://lkml.kernel.org/r/20190131161046.21886-1-anders.roxell@linaro.org [rppt@linux.ibm.com: fix format strings for panics after memblock_alloc] Link: http://lkml.kernel.org/r/1548950940-15145-1-git-send-email-rppt@linux.ibm.com [rppt@linux.ibm.com: don't panic if the allocation in sparse_buffer_init fails] Link: http://lkml.kernel.org/r/20190131074018.GD28876@rapoport-lnx [akpm@linux-foundation.org: fix xtensa printk warning] Link: http://lkml.kernel.org/r/1548057848-15136-20-git-send-email-rppt@linux.ibm.comSigned-off-by:Anders Roxell <anders.roxell@linaro.org> Reviewed-by: Guo Ren <ren_guo@c-sky.com> [c-sky] Acked-by: Paul Burton <paul.burton@mips.com> [MIPS] Acked-by: Heiko Carstens <heiko.carstens@de.ibm.com> [s390] Reviewed-by: Juergen Gross <jgross@suse.com> [Xen] Reviewed-by: Geert Uytterhoeven <geert@linux-m68k.org> [m68k] Acked-by: Max Filippov <jcmvbkbc@gmail.com> [xtensa] Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Christophe Leroy <christophe.leroy@c-s.fr> Cc: Christoph Hellwig <hch@lst.de> Cc: "David S.

Add panic() calls if memblock_alloc*() returns NULL. Most of the changes are simply addition of if(!ptr) panic(); statements after the calls to memblock_alloc*() variants. Exceptions are pcpu_populate_pte() and kernel_map_range() that were slightly refactored to accommodate the change.
