Just finished bisecting mmotm, to find why a test which used to take
four minutes now took more than an hour: the __buffer_migrate_page()
cleanup left behind a get_page() which attach_page_private() now does.
Fixes: cd0f37154443 ("mm/migrate.c: call detach_page_private to cleanup code")

Commit 8d58f222e85f ("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.
Fixes: 8d58f222e85f ("ubsan: disable UBSAN_ALIGNMENT under COMPILE_TEST")

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 real version just had a few callers that can open code it and remove
one layer of indirection. The nommu stub was public but only had a single
caller, so remove it and avoid a CONFIG_MMU ifdef in vmalloc.h.

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. Replace the
mapping side with a remap_isa_range helper in isa-bridge.c that hard codes
all the known arguments, and just remove __iounmap_at in favour of open
coding it in the only caller.

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. In
the non-contiguous (IOMMU) case this requires an extra find_vm_area,
but given that this isn't a fast path function that is a small price
to pay.
