this.  The patch seems to be lost in the leaves of the original
discussion [1], so resending.

[1] https://lore.kernel.org/r/alpine.DEB.2.21.2001281813130.745@www.lameter.com

Kmem caches are internal kernel structures so it is strange that
userspace notifiers would be needed.  And I am not aware of any use of
these notifiers.  These notifiers may just exist because in the initial
slub release the sysfs code was copied from another subsystem.

controllers which can be used simultaneously. Currently
android_device_create() assumes only one gadget instance is ever

class, resulting in a crash if a second gadget is registered since the
global android_device pointer gets overwritten with -EEXIST.

mm: fix wrong kasan report [1/1]

PD#SWPL-13281

Problem:
There are 2 types of wrong kasan report after merge change of
save wasted slab.
1, slab-out-of-bounds, which is caused by krealloc set shadow
   memory out-of-range, since tail of page was freed.
2, use-after-free, which is caused by kasan_free_pages called
   after a page freed. Because this function already called in
   free_page, so it marked shadow memory twice.

Solution:
1, make shadow do not out of range if a tail page was freed and
   been realloc again.
2, remove call of kasan_free_pages.

eea59020a7f2, the edits to arch/arm64/mm/proc.S were dropped because

paths were later merged together in android-4.9. The missing edits to
proc.S should have been added in during the merge, but were not. This
change restores those edits. The original upstream change description

originally.

Commit 6d99b68933fbcf51f84fcbba49246ce1209ec193 upstream.

Now that KVM uses tpidr_el2 in the same way as Linux's cpu_offset in
tpidr_el1, merge the two. This saves KVM from save/restoring tpidr_el1

without triggering world-switch.

arm64: relocatable: fix inconsistencies in linker script and options

commit 3bbd3db86470c701091fb1d67f1fab6621debf50 upstream.

readelf complains about the section layout of vmlinux when building
with CONFIG_RELOCATABLE=y (for KASLR):

  readelf: Warning: [21]: Link field (0) should index a symtab section.
  readelf: Warning: [21]: Info field (0) should index a relocatable section.

Also, it seems that our use of '-pie -shared' is contradictory, and
thus ambiguous. In general, the way KASLR is wired up at the moment
is highly tailored to how ld.bfd happens to implement (and conflate)
PIE executables and shared libraries, so given the current effort to
support other toolchains, let's fix some of these issues as well.

- Drop the -pie linker argument and just leave -shared. In ld.bfd,
  the differences between them are unclear (except for the ELF type
  of the produced image [0]) but lld chokes on seeing both at the
  same time.

- Rename the .rela output section to .rela.dyn, as is customary for
  shared libraries and PIE executables, so that it is not misidentified
  by readelf as a static relocation section (producing the warnings
  above).

- Pass the -z notext and -z norelro options to explicitly instruct the
  linker to permit text relocations, and to omit the RELRO program
  header (which requires a certain section layout that we don't adhere
  to in the kernel). These are the defaults for current versions of
  ld.bfd.

- Discard .eh_frame and .gnu.hash sections to avoid them from being
  emitted between .head.text and .text, screwing up the section layout.

These changes only affect the ELF image, and produce the same binary
image.

Since 4b936885a (v2.6.32) all inodes on sockfs and pipefs are disconnected.
It caused filesystem specific code in smack_d_instantiate to be skipped,

As a result all sockfs inodes had the Smack label set to floor.

label is not important. But there are special cases that were broken.
One example would be calling fcntl with F_SETOWN command on a socket fd.
