Commit 8d58f222 ("ubsan: disable UBSAN_ALIGNMENT under COMPILE_TEST") tried to fix the pathological results of UBSAN_ALIGNMENT with UBSAN_TRAP (which objtool would rightly scream about), but it made an assumption about how COMPILE_TEST gets set (it is not set for randconfig). As a result, we need a bigger hammer here: just don't allow the alignment checks with the trap mode.

KASAN uses a single cc-option invocation to disable both conserve-stack and stack-protector flags. The former flag is not present in Clang, which causes cc-option to fail, and results in stack-protector being enabled. Fix by using separate cc-option calls for each flag. Also collect all flags in a variable to avoid calling cc-option multiple times for different files.

Patch series "mm: Get rid of vmalloc_sync_(un)mappings()", v3. After the recent issue with vmalloc and tracing code[1] on x86 and a long history of previous issues related to the vmalloc_sync_mappings() interface, I thought the time has come to remove it. Please see [2], [3], and [4] for some other issues in the past. The patches add tracking of page-table directory changes to the vmalloc and ioremap code. Depending on which page-table levels changes have been made, a new per-arch function is called: arch_sync_kernel_mappings(). On x86-64 with 4-level paging, this function will not be called more than 64 times in a systems runtime (because vmalloc-space takes 64 PGD entries which are only populated, but never cleared). As a side effect this also allows to get rid of vmalloc faults on x86, making it safe to touch vmalloc'ed memory in the page-fault handler. Note that this potentially includes per-cpu memory. This patch (of 7): Add page-table allocation functions which will keep track of changed directory entries. They are needed for new PGD, P4D, PUD, and PMD entries and will be used in vmalloc and ioremap code to decide whether any changes in the kernel mappings need to be synchronized between page-tables in the system.

The non-cached vmalloc mapping was initially added as a hack for the first-gen amigaone platform (6xx/book32s), isn't fully supported upstream, and which used the legacy radeon driver together with non-coherent DMA. However this only ever worked reliably for DRI . Remove the hack as it is the last user of __vmalloc passing a page protection flag other than PAGE_KERNEL and didn't do anything for other platforms with non-coherent DMA.

This allows to unexport map_vm_area and unmap_kernel_range, which are rather deep internal and should not be available to modules, as they for example allow fine grained control of mapping permissions, and also allow splitting the setup of a vmalloc area and the actual mapping and thus expose vmalloc internals. zsmalloc is typically built-in and continues to work (just like the percpu-vm code using a similar patter), while modular zsmalloc also continues to work, but must use copies.

These helpers are only used for remapping the ISA I/O base.

Factor code shared between pci_64 and electra_cf into a ioremap_pbh helper that follows the normal ioremap semantics, and returns a useful __iomem pointer. Note that it opencodes __ioremap_at as we know from the callers the slab is available. Switch pci_64 to also store the result as __iomem pointer, and unmap the result using iounmap instead of force casting and using vmalloc APIs.

Replace the open coded instance of vmap with the actual function.
