Commit bbff39cc6cbc ("hugetlb: allocate vma lock for all sharable vmas")
removed the pmd sharable checks in the vma lock helper routines. However,
it left the functional version of helper routines behind #ifdef
CONFIG_ARCH_WANT_HUGE_PMD_SHARE. Therefore, the vma lock is not being
used for sharable vmas on architectures that do not support pmd sharing.
On these architectures, a potential fault/truncation race is exposed that
could leave pages in a hugetlb file past i_size until the file is removed.
Move the functional vma lock helpers outside the ifdef, and remove the
non-functional stubs. Since the vma lock is not just for pmd sharing,
rename the routine __vma_shareable_flags_pmd.

When encountering any vma in the range with policy other than MPOL_BIND or
MPOL_PREFERRED_MANY, an error is returned without issuing a mpol_put on
the policy just allocated with mpol_dup().
This allows arbitrary users to leak kernel memory.

Since 6.1 we have noticed random rpm install failures that were tracked to
mremap() returning -ENOMEM and to commit ca3d76b0aa80 ("mm: add merging
after mremap resize").
The problem occurs when mremap() expands a VMA in place, but using an
starting address that's not vma->vm_start, but somewhere in the middle.
The extension_pgoff calculation introduced by the commit is wrong in that
case, so vma_merge() fails due to pgoffs not being compatible. Fix the
calculation.
By the way it seems that the situations, where rpm now expands a vma from
the middle, were made possible also due to that commit, thanks to the
improved vma merging. Yet it should work just fine, except for the buggy
calculation.

Two selftests drivers exist under the copyleft-next license.
These drivers were added prior to SPDX practice taking full swing

documented, embrace it and remove the boiler plate.

Add the full text of the copyleft-next-0.3.1 license to the kernel
tree as well as the required tags for reference and tooling.
The license text was copied directly from the copyleft-next project's
git tree [0].
Discussion of using copyleft-next-0.3.1 on Linux started since June,
2016 [1]. In the end Linus' preference was to have drivers use
MODULE_LICENSE("GPL") to make it clear that the GPL applies when it
comes to Linux [2]. Additionally, even though copyleft-next-0.3.1 has
been found to be to be GPLv2 compatible by three attorneys at SUSE and
Redhat [3], to err on the side of caution we simply recommend to
always use the "OR" language for this license [4].
Even though it has been a goal of the project to be GPL-v2 compatible
to be certain in 2016 I asked for a clarification about what makes
copyleft-next GPLv2 compatible and also asked for a summary of
benefits. This prompted some small minor changes to make compatibility
even further clear and as of copyleft 0.3.1 compatibility should
be crystal clear [5].
The summary of why copyleft-next 0.3.1 is compatible with GPLv2
is explained as follows:
Like GPLv2, copyleft-next requires distribution of derivative works
("Derived Works" in copyleft-next 0.3.x) to be under the same license.
Ordinarily this would make the two licenses incompatible. However,
copyleft-next 0.3.1 says: "If the Derived Work includes material
licensed under the GPL, You may instead license the Derived Work under
the GPL." "GPL" is defined to include GPLv2.
In practice this means copyleft-next code in Linux may be licensed
under the GPL2, however there are additional obvious gains for
bringing contributions from Linux outbound where copyleft-next is
preferred. A summary of benefits why projects outside of Linux might
prefer to use copyleft-next >= 0.3.1 over GPLv2:
o It is much shorter and simpler
o It has an explicit patent license grant, unlike GPLv2
o Its notice preservation conditions are clearer
o More free software/open source licenses are compatible
with it (via section 4)
o The source code requirement triggered by binary distribution
is much simpler in a procedural sense
o Recipients potentially have a contract claim against distributors
who are noncompliant with the source code requirement
o There is a built-in inbound=outbound policy for upstream
contributions (cf. Apache License 2.0 section 5)
o There are disincentives to engage in the controversial practice
of copyleft/ proprietary dual-licensing
o In 15 years copyleft expires, which can be advantageous
for legacy code
o There are explicit disincentives to bringing patent infringement
claims accusing the licensed work of infringement (see 10b)
o There is a cure period for licensees who are not compliant
with the license (there is no cure opportunity in GPLv2)
o copyleft-next has a 'built-in or-later' provision
The first driver submission to Linux under this dual strategy was
lib/test_sysctl.c through commit 9308f2f9e7f05 ("test_sysctl: add
dedicated proc sysctl test driver") merged in July 2017. Shortly after
that I also added test_kmod through commit d9c6a72d6fa29 ("kmod: add
test driver to stress test the module loader") in the same month. These
two drivers went in just a few months before the SPDX license practice
kicked in. In 2018 Kuno Woudt went through the process to get SPDX
identifiers for copyleft-next [6] [7]. Although there are SPDX tags
for copyleft-next-0.3.0, we only document use in Linux starting from
copyleft-next-0.3.1 which makes GPLv2 compatibility crystal clear.
This patch will let us update the two Linux selftest drivers in
subsequent patches with their respective SPDX license identifiers and
let us remove repetitive license boiler plate.

I do not read a strict requirement on /chosen node in either ePAPR or in
Documentation/devicetree. Help text for CONFIG_CMDLINE and
CONFIG_CMDLINE_EXTEND doesn't make their behavior explicitly dependent on
the presence of /chosen or the presense of /chosen/bootargs.
However the early check for /chosen and bailing out in
early_init_dt_scan_chosen() skips CONFIG_CMDLINE handling which is not
really related to /chosen node or the particular method of passing cmdline
from bootloader.
This leads to counterintuitive combinations (assuming
CONFIG_CMDLINE_EXTEND=y):
a) bootargs="foo", CONFIG_CMDLINE="bar" => cmdline=="foo bar"
b) /chosen missing, CONFIG_CMDLINE="bar" => cmdline==""
c) bootargs="", CONFIG_CMDLINE="bar" => cmdline==" bar"
Move CONFIG_CMDLINE handling outside of early_init_dt_scan_chosen() so that
cases b and c above result in the same cmdline.

Pull parisc updates from Helge Deller:
"There is one noteable patch, which allows the parisc kernel to use the
same MADV_xxx constants as the other architectures going forward. With
that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on
others) which is different. To prevent an ABI breakage, a wrapper is
included which translates old MADV values to the new ones, so existing
userspace isn't affected. Reason for that patch is, that some
applications wrongly used the standard MADV_xxx values even on some
non-x86 platforms and as such those programs failed to run correctly
on parisc (examples are qemu-user, tor browser and boringssl).
Then the kgdb console and the LED code received some fixes, and some
0-day warnings are now gone. Finally, the very last compile warning
which was visible during a kernel build is now fixed too (in the vDSO
code).
The majority of the patches are tagged for stable series and in
summary this patchset is quite small and drops more code than it adds:
Fixes:
- Fix potential null-ptr-deref in start_task()
- Fix kgdb console on serial port
- Add missing FORCE prerequisites in Makefile
- Drop PMD_SHIFT from calculation in pgtable.h
Enhancements:
- Implement a wrapper to align madvise() MADV_* constants with other
architectures
- If machine supports running MPE/XL, show the MPE model string
Cleanups:
- Drop duplicate kgdb console code
- Indenting fixes in setup_cmdline()"
* tag 'parisc-for-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Show MPE/iX model string at bootup
parisc: Add missing FORCE prerequisites in Makefile
parisc: Move pdc_result struct to firmware.c

Some (mostly 64-bit machines) machines allow to run MPE/iX and report the MPE
model string via firmware call. Enhance the pdc_model_sysmodel() function to
report that model string.
Note that some 32-bit machines like the B160L wrongly report success for the
firmware call, so include a check to prevent showing wrong info.

Adjust some MADV_XXX constants to be in sync what their values are on
all other platforms. There is currently no reason to have an own
numbering on parisc, but it requires workarounds in many userspace
sources (e.g. glibc, qemu, ...) - which are often forgotten and thus
introduce bugs and different behaviour on parisc.
A wrapper avoids an ABI breakage for existing userspace applications by
translating any old values to the new ones, so this change allows us to
move over all programs to the new ABI over time.

Due to compiler optimizations like inlining, there are cases where
MMIO traces using _THIS_IP_ for caller information might not be
sufficient to provide accurate debug traces.
1) With optimizations (Seen with GCC):
In this case, _THIS_IP_ works fine and prints the caller information
since it will be inlined into the caller and we get the debug traces
on who made the MMIO access, for ex:
rwmmio_read: qcom_smmu_tlb_sync+0xe0/0x1b0 width=32 addr=0xffff8000087447f4
rwmmio_post_read: qcom_smmu_tlb_sync+0xe0/0x1b0 width=32 val=0x0 addr=0xffff8000087447f4
2) Without optimizations (Seen with Clang):
_THIS_IP_ will not be sufficient in this case as it will print only
the MMIO accessors itself which is of not much use since it is not
inlined as below for example:
rwmmio_read: readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: readl+0x48/0x80 width=32 val=0x4 addr=0xffff8000087447f4
So in order to handle this second case as well irrespective of the compiler
optimizations, add _RET_IP_ to MMIO trace to make it provide more accurate
debug information in all these scenarios.
Before:
rwmmio_read: readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: readl+0x48/0x80 width=32 val=0x4 addr=0xffff8000087447f4
After:
rwmmio_read: qcom_smmu_tlb_sync+0xe0/0x1b0 -> readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: qcom_smmu_tlb_sync+0xe0/0x1b0 -> readl+0x4/0x80 width=32 val=0x0 addr=0xffff8000087447f4

Commit bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining
of some byteswap operations") added __always_inline to swab functions
and commit 283d75737837 ("uapi/linux/stddef.h: Provide __always_inline to
userspace headers") added a definition of __always_inline for use in
exported headers when the kernel's compiler.h is not available.
However, since swab.h does not include stddef.h, if the header soup does
not indirectly include it, the definition of __always_inline is missing,
resulting in a compilation failure, which was observed compiling the
perf tool using exported headers containing this commit:
In file included from /usr/include/linux/byteorder/little_endian.h:12:0,
from /usr/include/asm/byteorder.h:14,
from tools/include/uapi/linux/perf_event.h:20,
from perf.h:8,
from builtin-bench.c:18:
/usr/include/linux/swab.h:160:8: error: unknown type name `__always_inline'
static __always_inline __u16 __swab16p(const __u16 *p)
Fix this by replacing the inclusion of linux/compiler.h with
linux/stddef.h to ensure that we pick up that definition if required,
without relying on it's indirect inclusion. compiler.h is then included
indirectly, via stddef.h.

The actual clock feeding into the Mali GPU on the MT8183 is from the
clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN
block, which itself is simply a pass-through placeholder for the MFGPLL
in the APMIXEDSYS block.
Fix the hardware description with the correct clock reference.
