do_common_tools is a mode specifier, it is on when we want tools and off when we do not want tools. It is intended to be flipped by the bootstrap modes. Whether those common tools are actually built is determined by whether we are calling binary or binary-arch not related to whether we want those packages to have content. Enable this unconditionally. This allows us to build the indep packages on any arch is needed. BugLink: http://bugs.launchpad.net/bugs/1764794Signed-off-by:

If optional .mk variable 'ship_extras_package' is explicitly set to false, then do not construct the linux-image-extra package; instead just log all of the "extra" modules which were pointlessly built yet won't be shipped.

When we install linux-image we have to run kernel postinst.d support in case this kernel has no linux-image-extra. Should it have an extra and we install we then have to assume that is being installed cold and that the same processing is neeed. If we are installing both at the same time, we necessarily trigger kernel postinst.d twice. As this includes rebuilding the initramfs and reconfiguring the boot loader this is very inefficient. For removal of linux-image-extra when we remove the package we also need to run postinst.d handling in order to pare down the initramfs to linux-image contents only. However when we are removing both packages we immediatly remove the rebuilt initramfs. Doubly annoying. This patch switches us to using a trigger against the linux-image package for all postinst.d and postrm.d handling. On installation postinst.d gets triggered twice once by linux-image and once by linux-image-extra. As triggers are non-cumulative we will only run this processing once. When removing both packages we will trigger postinst.d from linux-image-extra and then in linux-image postrm.d we effectivly ignore the pending trigger and simply run the postrm.d. This prevents us from rebuilding the initramfs. BugLink: http://bugs.launchpad.net/bugs/1764794Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1811647 commit 3569dd07 upstream. The Intel IOMMU driver opportunistically skips a few top level page tables from the domain paging directory while programming the IOMMU context entry. However there is an implicit assumption in the code that domain's adjusted guest address width (agaw) would always be greater than IOMMU's agaw. The IOMMU capabilities in an upcoming platform cause the domain's agaw to be lower than IOMMU's agaw. The issue is seen when the IOMMU supports both 4-level and 5-level paging. The domain builds a 4-level page table based on agaw of 2. However the IOMMU's agaw is set as 3 (5-level). In this case the code incorrectly tries to skip page page table levels. This causes the IOMMU driver to avoid programming the context entry. The fix handles this case and programs the context entry accordingly.

BugLink: https://bugs.launchpad.net/bugs/1811647 commit 574d356b upstream. If the requested msize is too small (either from command line argument or from the server version reply), we won't get any work done. If it's *really* too small, nothing will work, and this got caught by syzbot recently (on a new kmem_cache_create_usercopy() call) Just set a minimum msize to 4k in both code paths, until someone complains they have a use-case for a smaller msize. We need to check in both mount option and server reply individually because the msize for the first version request would be unchecked with just a global check on clnt->msize.

However, the expired cache_head may be waiting for a reply from a previously submitted request. Such a cache_head has an increased refcounter and therefore it won't be freed after cache_put(freeme). Because the cache_head was removed from the hash it cannot be found during cache_clean() and can be leaked forever, together with stalled cache_request and other taken resources. In our case we noticed it because an entry in the export cache was holding a reference on a filesystem.

Given the fact that devm_memremap_pages() requires a percpu_ref that is torn down by devm_memremap_pages_release() the current support for mapping RAM is broken. Support for remapping "System RAM" has been broken since the beginning and there is no existing user of this this code path, so just kill the support and make it an explicit error. This cleanup also simplifies a follow-on patch to fix the error path when setting a devm release action for devm_memremap_pages_release() fails.

BugLink: https://bugs.launchpad.net/bugs/1811647 commit 808153e1 upstream. devm_memremap_pages() is a facility that can create struct page entries for any arbitrary range and give drivers the ability to subvert core aspects of page management. Specifically the facility is tightly integrated with the kernel's memory hotplug functionality. It injects an altmap argument deep into the architecture specific vmemmap implementation to allow allocating from specific reserved pages, and it has Linux specific assumptions about page structure reference counting relative to get_user_pages() and get_user_pages_fast(). It was an oversight and a mistake that this was not marked EXPORT_SYMBOL_GPL from the outset. Again, devm_memremap_pagex() exposes and relies upon core kernel internal assumptions and will continue to evolve along with 'struct page', memory hotplug, and support for new memory types / topologies. Only an in-kernel GPL-only driver is expected to keep up with this ongoing evolution. This interface, and functionality derived from this interface, is not suitable for kernel-external drivers.
