In commit:
4b53a3412d ("sched/core: Remove the tsk_nr_cpus_allowed() wrapper")
the tsk_nr_cpus_allowed() wrapper was removed. There was not
much difference in !RT but in RT we used this to implement
migrate_disable(). Within a migrate_disable() section the CPU mask is
restricted to single CPU while the "normal" CPU mask remains untouched.
As an alternative implementation Ingo suggested to use:
struct task_struct {
const cpumask_t *cpus_ptr;
cpumask_t cpus_mask;
};
with
t->cpus_ptr = &t->cpus_mask;
In -RT we then can switch the cpus_ptr to:
t->cpus_ptr = &cpumask_of(task_cpu(p));
in a migration disabled region. The rules are simple:
- Code that 'uses' ->cpus_allowed would use the pointer.
- Code that 'modifies' ->cpus_allowed would use the direct mask.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

The pistachio platform uses the U-Boot bootloader & generally boots a
kernel in the uImage format. As such it's useful to build one when
building the kernel, but to do so currently requires the user to
manually specify a uImage target on the make command line.
Make uImage.gz the pistachio platform's default build target, so that
the default is to build a kernel image that we can actually boot on a
board such as the MIPS Creator Ci40.
Marked for stable backport as far as v4.1 where pistachio support was
introduced. This is primarily useful for CI systems such as kernelci.org
which will benefit from us building a suitable image which can then be
booted as part of automated testing, extending our test coverage to the
affected stable branches.

virt_addr_valid() really returns a boolean value, but currently uses an
integer to represent it. Switch to the bool type to make it clearer that
we really are returning a true or false value.

The virt_addr_valid() function is meant to return true iff
virt_to_page() will return a valid struct page reference. This is true
iff the address provided is found within the unmapped address range
between PAGE_OFFSET & MAP_BASE, but we don't currently check for that
condition. Instead we simply mask the address to obtain what will be a
physical address if the virtual address is indeed in the desired range,
shift it to form a PFN & then call pfn_valid(). This can incorrectly
return true if called with a virtual address which, after masking,
happens to form a physical address corresponding to a valid PFN.
For example we may vmalloc an address in the kernel mapped region
starting a MAP_BASE & obtain the virtual address:
addr = 0xc000000000002000
When masked by virt_to_phys(), which uses __pa() & in turn CPHYSADDR(),
we obtain the following (bogus) physical address:
addr = 0x2000
In a common system with PHYS_OFFSET=0 this will correspond to a valid
struct page which should really be accessed by virtual address
PAGE_OFFSET+0x2000, causing virt_addr_valid() to incorrectly return 1
indicating that the original address corresponds to a struct page.
This is equivalent to the ARM64 change made in commit ca219452c6
("arm64: Correctly bounds check virt_addr_valid").
This fixes fallout when hardened usercopy is enabled caused by the
related commit 517e1fbeb6 ("mm/usercopy: Drop extra
is_vmalloc_or_module() check") which removed a check for the vmalloc
range that was present from the introduction of the hardened usercopy
feature.

As synchronous exceptions really only make sense against the current
task (otherwise how are you synchronous) remove the task parameter
from from force_sig_fault to make it explicit that is what is going
on.
The two known exceptions that deliver a synchronous exception to a
stopped ptraced task have already been changed to
force_sig_fault_to_task.
The callers have been changed with the following emacs regular expression
(with obvious variations on the architectures that take more arguments)
to avoid typos:
force_sig_fault[(]\([^,]+\)[,]\([^,]+\)[,]\([^,]+\)[,]\W+current[)]
->
force_sig_fault(\1,\2,\3)

In preparation for removing the task parameter from force_sig_fault
introduce force_sig_fault_to_task and use it for the two cases where
it matters.
On mips force_fcr31_sig calls force_sig_fault and is called on either
the current task, or a task that is suspended and is being switched to
by the scheduler. This is safe because the task being switched to by
the scheduler is guaranteed to be suspended. This ensures that
task->sighand is stable while the signal is delivered to it.
On parisc user_enable_single_step calls force_sig_fault and is in turn
called by ptrace_request. The function ptrace_request always calls
user_enable_single_step on a child that is stopped for tracing. The
child being traced and not reaped ensures that child->sighand is not
NULL, and that the child will not change child->sighand.

KVM_CAP_MAX_VCPU_ID is currently always reporting KVM_MAX_VCPU_ID on all
architectures. However, on s390x, the amount of usable CPUs is determined
during runtime - it is depending on the features of the machine the code
is running on. Since we are using the vcpu_id as an index into the SCA
structures that are defined by the hardware (see e.g. the sca_add_vcpu()
function), it is not only the amount of CPUs that is limited by the hard-
ware, but also the range of IDs that we can use.
Thus KVM_CAP_MAX_VCPU_ID must be determined during runtime on s390x, too.
So the handling of KVM_CAP_MAX_VCPU_ID has to be moved from the common
code into the architecture specific code, and on s390x we have to return
the same value here as for KVM_CAP_MAX_VCPUS.
This problem has been discovered with the kvm_create_max_vcpus selftest.
With this change applied, the selftest now passes on s390x, too.

^~~~~~~~~~
The cause of the error is a missing space after the compiler flag -I .
Kbuild used to have a global restriction "no space after -I", but
commit 48f6e3cf5b ("kbuild: do not drop -I without parameter") got
rid of it. Having a space after -I is no longer a big deal as far as
Kbuild is concerned.
It is still a big deal for MIPS because arch/mips/vdso/Makefile
filters the header search paths, like this:
ccflags-vdso := \
$(filter -I%,$(KBUILD_CFLAGS)) \
..., which relies on the assumption that there is no space after -I .

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b
("kbuild: do not drop -I without parameter").

Most architectures do not need the memblock memory after the page
allocator is initialized, but only few enable ARCH_DISCARD_MEMBLOCK in the
arch Kconfig.
Replacing ARCH_DISCARD_MEMBLOCK with ARCH_KEEP_MEMBLOCK and inverting the
logic makes it clear which architectures actually use memblock after
system initialization and skips the necessity to add ARCH_DISCARD_MEMBLOCK
to the architectures that are still missing that option.

Various architectures including x86 poison the freed initrd memory. Do
the same in the generic free_initrd_mem implementation and switch a few
more architectures that are identical to the generic code over to it now.

To facilitate additional options to get_user_pages_fast() change the
singular write parameter to be gup_flags.
This patch does not change any functionality. New functionality will
follow in subsequent patches.
Some of the get_user_pages_fast() call sites were unchanged because they
already passed FOLL_WRITE or 0 for the write parameter.
NOTE: It was suggested to change the ordering of the get_user_pages_fast()
arguments to ensure that callers were converted. This breaks the current
GUP call site convention of having the returned pages be the final
parameter. So the suggestion was rejected.

Appended DTB support is mostly intended to be used on legacy systems,
but it is a valid feature that can be enabled for generic platform,
which currently doesn't support it - if selected, the appended DTB will
be ignored by the platform startup code.
During kernel startup, the appended DTB's location is stored in
fw_passed_dtb if the init code finds what appears to be a valid DTB.
Otherwise (if a0 == -2), a1 is stored in fw_passed_dtb, so either way it
will always point to either a user-passed DTB or built-in DTB.

around because we've finally gotten around to fixing some long standing issues.
There's still work to do though, so this PR is largely laying down the
foundation for all the driver changes to come in the next merge window.
The first problem we're alleviating is how parents of clks are specified. With
the new method, we should see lots of drivers migrate away from the current
design of string comparisons on the entire clk tree to a more direct method
where they can use clk_hw pointers or more localized names specified in DT or
via clkdev. This should reduce our reliance on string comparisons for all the
topology description logic that we've been using for years and hopefully speed
some things up while avoiding problems we have with generating clk names.
Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't really
helping anyone and we introduced big-endian versions of the basic clk types so
that we can get rid of clk_{readl,writel}(). Both of these are things that
driver developers have tried to use over the years that I typically bat away
during code reviews because they're not useful. It's great to see these two
things go away so maintainers can save time not worrying about these things.
On the driver side we got the usual collection of new SoC support and
non-critical fixes and updates to existing code. The big topics that stand out
are the new driver support for Mediatek MT8183 and MT8516 SoCs, Amlogic Meson8b
and G12a SoCs, and the SiFive FU540 SoC. The other patches in the driver pile
are mostly fixes for things that are being used for the first time or additions
for clks that couldn't be tested before because there wasn't a consumer driver
that exercised them. Details are below and also in the sub-maintainer tags.
Core:
- Remove clk_readl() and introduce BE versions of basic clk types
- Rewrite how clk parents can be specified to allow DT/clkdev lookups
- Removal of the CLK_IS_BASIC clk flag
- Framework documentation updates and fixes
New Drivers:
- Support for STM32F769
- AT91 sam9x60 PMC support
- SiFive FU540 PRCI and PLL support
- Qualcomm QCS404 CDSP clk support
- Qualcomm QCS404 Turing clk support
- Mediatek MT8183 clock support
- Mediatek MT8516 clock support
- Milbeaut M10V clk controller support
- Support for Cirrus Logic Lochnagar clks
Updates:
- Rework AT91 sckc DT bindings
- Fix slow RC oscillator issue on sama5d3
- Mark UFS clk as critical on Hi-Silicon hi3660 SoCs
- Various static analysis fixes/finds and const markings
- Video Engine (ECLK) support on Aspeed SoCs
- Xilinx ZynqMP Versal platform support
- Convert Xilinx ZynqMP driver to be struct oriented
- Fixes for Rockchip rk3328 and rk3288 SoCs
- Sub-type for Rockchip SoCs where mux and divider aren't a single register
- Remove SNVS clock from i.MX7UPL clock driver and bindings
- Improve i.MX5 clock driver for i.MX50 support
- Addition of ADC clock definition for Exynos 5410 SoC (Odroid XU)
- Export a new clock for the MBUS controller on the A13

Pull audit updates from Paul Moore:
"We've got a reasonably broad set of audit patches for the v5.2 merge
window, the highlights are below:
- The biggest change, and the source of all the arch/* changes, is
the patchset from Dmitry to help enable some of the work he is
doing around PTRACE_GET_SYSCALL_INFO.
To be honest, including this in the audit tree is a bit of a
stretch, but it does help move audit a little further along towards
proper syscall auditing for all arches, and everyone else seemed to
agree that audit was a "good" spot for this to land (or maybe they
just didn't want to merge it? dunno.).
- We can now audit time/NTP adjustments.
- We continue the work to connect associated audit records into a
single event"

Merge tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull pidfd updates from Christian Brauner:
"This patchset makes it possible to retrieve pidfds at process creation
time by introducing the new flag CLONE_PIDFD to the clone() system
call. Linus originally suggested to implement this as a new flag to
clone() instead of making it a separate system call.
After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
parent_tidptr argument. This means we can give back the associated pid
and the pidfd at the same time. Access to process metadata information
thus becomes rather trivial.
As has been agreed, CLONE_PIDFD creates file descriptors based on
anonymous inodes similar to the new mount api. They are made
unconditional by this patchset as they are now needed by core kernel
code (vfs, pidfd) even more than they already were before (timerfd,
signalfd, io_uring, epoll etc.). The core patchset is rather small.
The bulky looking changelist is caused by David's very simple changes
to Kconfig to make anon inodes unconditional.
A pidfd comes with additional information in fdinfo if the kernel
supports procfs. The fdinfo file contains the pid of the process in
the callers pid namespace in the same format as the procfs status
file, i.e. "Pid:\t%d".
To remove worries about missing metadata access this patchset comes
with a sample/test program that illustrates how a combination of
CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
access to process metadata through /proc/<pid>.
Further work based on this patchset has been done by Joel. His work
makes pidfds pollable. It finished too late for this merge window. I
would prefer to have it sitting in linux-next for a while and send it
for inclusion during the 5.3 merge window"

The module support for the thermal subsystem makes little sense:
- some subsystems relying on it are not modules, thus forcing the
framework to be compiled in
- it is compiled in for almost every configs, the remaining ones
are a few platforms where I don't see why we can not switch the thermal
to 'y'. The drivers can stay in tristate.
- platforms need the thermal to be ready as soon as possible at boot time
in order to mitigate
Usually the subsystems framework are compiled-in and the plugs are as
module.
Remove the module option. The removal of the module related dead code will
come after this patch gets in or is acked.

Since memblock-patchset was introduced the reserved-memory nodes are
supported being declared in dt-files. So these nodes are actually parsed
during the arch setup procedure when the early_init_fdt_scan_reserved_mem()
method is called. But due to the arch-specific boot mem_map container
utilization we need to manually call the fdt_init_reserved_mem() method
after all the available and reserved memory has been moved to memblock.
The first function call performed before bootmem_init() by the
early_init_fdt_scan_reserved_mem() routine fails due to the lack of any
memblock memory regions to allocate from at that stage.

There are situations when memory regions coming from dts may be
too big for the platform physical address space. This especially
concerns XPA-capable systems. Bootloader may determine more than 4GB
memory available and pass it to the kernel over dts memory node, while
kernel is built without XPA/64BIT support. In this case the region
may either simply be truncated by add_memory_region() method
or by u64->phys_addr_t type casting. But in worst case the method
can even drop the memory region if it exceeds PHYS_ADDR_MAX size.
So lets make sure the retrieved from dts memory regions are valid,
and if some of them aren't, just manually truncate them with a warning
printed out.

memblock subsystem provides a method to optionally test the passed
memory region in case if it was requested via special kernel boot
argument. Lets add the function at the bottom of the arch_mem_init()
method. Testing at this point in the boot sequence should be safe since all
critical areas are now reserved and a minimum of allocations have been
done.

It is useful to have the whole memblock memory space printed to console
when basic memlock initializations are done. It can be performed by
ready-to-use method memblock_dump_all(), which prints the available
and reserved memory spaces if memblock=debug kernel parameter is
specified. Lets call it at the very end of arch_mem_init() function,
when all memblock memory and reserved regions are defined, but before
any serious allocation is performed.

It might be necessary to prevent the virtual mapping creation for a
requested memory region. For instance there is a "no-map" property
indicating exactly this feature. In this case we need to not only
reserve the specified region by pretending it doesn't exist in the
memory space, but completely remove the range from system just by
removing it from memblock. The same way it's done in default
early_init_dt_reserve_memory_arch() method.

Originally before legacy bootmem was removed, the memory for the range was
correctly reserved by reserve_bootmem_region(). But since memblock has been
selected for early memory allocation the function can be utilized only
after paging is fully initialized (as it is done by memblock_free_all()
function). So calling it from arch_mem_init() method is prone to errors,
and at this stage we need to reserve the memory in the memblock allocator.

Really the loop is pointless, since it walks over memblock-reserved
memory regions and mark them as reserved in memblock. Before
bootmem was removed from the kernel, this loop had been
used to map the memory reserved by CMA into the legacy bootmem
allocator. But now the early memory allocator is memblock,
which is used by CMA for reservation, so we don't need any mapping
anymore.

The reserved_end variable had been used by the bootmem_init() code
to find a lowest limit of memory available for memmap blob. The original
code just tried to find a free memory space higher than kernel was placed.
This limitation seems justified for the memmap ragion search process, but
I can't see any obvious reason to reserve the unused space below kernel
seeing some platforms place it much higher than standard 1MB. Moreover
the RELOCATION config enables it to be loaded at any memory address.
So lets reserve the memory occupied by the kernel only, leaving the region
below being free for allocations. After doing this we can now discard the
code freeing a space between kernel _text and VMLINUX_LOAD_ADDRESS symbols
since it's going to be free anyway (unless marked as reserved by
platforms).

configure_exception_vector() write to it unconditionally on systems
implementing MIPSr2 or higher, and removing the duplicate code in
per_cpu_trap_init(). The latter would have duplicated work on systems
with vectored interrupts, and didn't set BEV for safety like the

Currently we allocate the exception vector on systems which use a
vectored interrupt mode, but otherwise attempt to reuse whatever
exception vector the bootloader uses.
This can be problematic for a number of reasons:
1) The memory isn't properly marked reserved in the memblock
allocator. We've relied on the fact that EBase is generally in the
memory below the kernel image which we don't free, but this is
about to change.
2) Recent versions of U-Boot place their exception vector high in
kseg0, in memory which isn't protected by being lower than the
kernel anyway & can end up being clobbered.
3) We are unnecessarily reliant upon there being memory at the address
EBase points to upon entry to the kernel. This is often the case,
but if the bootloader doesn't configure EBase & leaves it with its
default value then we rely upon there being memory at physical
address 0 for no good reason.
Improve this situation by allocating the exception vector in all cases
when running on MIPSr2 or higher, and reserving the memory for MIPSr1 or
lower. This ensures we don't clobber the exception vector in any
configuration, and for MIPSr2 & higher removes the need for memory at
physical address 0.

obtained a virtual address using memblock_alloc(), converted it to a

This flag was historically used to indicate that a clk is a "basic" type
of clk like a mux, divider, gate, etc. This never turned out to be very
useful though because it was hard to cleanly split "basic" clks from
other clks in a system. This one flag was a way for type introspection
and it just didn't scale. If anything, it was used by the TI clk driver
to indicate that a clk_hw wasn't contained in the SoC specific clk
structure. We can get rid of this define now that TI is finding those
clks a different way.

Before bootmem was completely removed from the kernel, the last loop
in the bootmem_init() had been used to reserve the correspondingly
marked regions, initialize sparsemem sections and to free the low memory
pages, which then would be used for early memory allocations. After the
bootmem removing patchset had been merged the loop was left to do the first
two things only. But it didn't do them quite well.
First of all it leaves the BOOT_MEM_INIT_RAM memory types unreserved,
which is definitely bug (although it isn't noticeable due to being used
by the kernel region only, which is fully marked as reserved). Secondly
the reservation is supposed to be done for any memory including the
high one. (I couldn't figure out why the highmem was ignored in the first
place, since platforms and dts' may declare any memory region for
reservation) Thirdly the reserved_end variable had been used here to not
accidentally free memory occupied by kernel. Since we already reserved the
corresponding region higher in this method there is no need in using the
variable here anymore. Fourthly the sparsemem should be aware of all the
memory types in the system including the ROM_DATA even if it is going to
be reserved for the whole system uptime. Finally after all these notes are
fixed the loop of memory reservation can be freely merged into the memory
installation loop as it's done in this patch.

There is a pointless code left in the bootmem_init() method since
the bootmem allocator removal. First part resides the PFN ranges
calculation loop. The conditional expressions and continue operator
are useless there, since nothing is done after them. Second part is
in RAM ranges installation loop. We can simplify the conditions cascade
a bit without much of the logic redefinition, so to reduce the code
length. In particular the end boundary value can be verified after
the possible reduction to be below max_low_pfn.

Current MIPS platform code makes sure the kernel text, data and init
sections are added to the boot memory map pool right after the
arch-specific memory setup method has been executed. But for some reason
the MIPS platform code skipped the kernel .bss section, which definitely
should be in the boot mem pool as well in any case. Lets fix this just be
adding the space between __bss_start and __bss_stop.

Pull in v5.1-rc6 to resolve two conflicts. One is in BFQ, in just a
comment, and is trivial. The other one is a conflict due to a later fix
in the bio multi-page work, and needs a bit more care.

The 'timeval' and 'timespec' data structures used for socket timestamps
are going to be redefined in user space based on 64-bit time_t in future
versions of the C library to deal with the y2038 overflow problem,
which breaks the ABI definition.
Unlike many modern ioctl commands, SIOCGSTAMP and SIOCGSTAMPNS do not
use the _IOR() macro to encode the size of the transferred data, so it
remains ambiguous whether the application uses the old or new layout.
The best workaround I could find is rather ugly: we redefine the command
code based on the size of the respective data structure with a ternary
operator. This lets it get evaluated as late as possible, hopefully after
that structure is visible to the caller. We cannot use an #ifdef here,
because inux/sockios.h might have been included before any libc header
that could determine the size of time_t.
The ioctl implementation now interprets the new command codes as always
referring to the 64-bit structure on all architectures, while the old
architecture specific command code still refers to the old architecture
specific layout. The new command number is only used when they are
actually different.

MTD_NAND is large and encloses much more than what the symbol is
actually used for: raw NAND. Clarify the symbol by naming it
MTD_RAW_NAND instead.

The software Hamming ECC correction implementation is referred as
MTD_NAND_ECC which is too generic. Rename it
MTD_NAND_ECC_SW_HAMMING. Also rename MTD_NAND_ECC_SMC which is an
SMC quirk in the Hamming implementation as
MTD_NAND_ECC_SW_HAMMING_SMC.

There is no point in having two distinct entries, merge them and
rename the symbol for more clarity: MTD_NAND_ECC_SW_BCH
