arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM
The semantics of pfn_valid() is to check presence of the memory map for a
PFN and not whether a PFN is in RAM. The memory map may be present for a
hole in the physical memory and if such hole corresponds to an MMIO range,
__arm_ioremap_pfn_caller() will produce a WARN() and fail:

riscv: Introduce structure that group all variables regarding kernel mapping
We have a lot of variables that are used to hold kernel mapping addresses, offsets between physical and virtual mappings and some others used for XIP kernels: they are all defined at different places in mm/init.c, so group them into a single structure with, for some of them, more explicit and concise names.

gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp, gpio-pcf857x
- cleanup of probe functions in many drivers from Alexandru Ardelean, mostly
dropping unnecessary calls to platform_set_drvdata() and removing error
messages where none are needed (handled by the subsystem already)
- several improvements to the core gpiolib and the sysfs interface code from
Andy Shevchenko
- conversion of the gpio-xilinx driver to using the bitmap API + improvements
of suspend/resume handling + minor tweaks
- convert the gpio-stmpe to using devres helpers exclusively in probe for
improved robustness
- updates for the generic gpio-regmap driver
- updates for the gpio-dwapb driver
- support for a new model in gpio-pca953x
- cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene

ALSA: bebob: correct duplicated entries with TerraTec OUI
ALSA bebob driver has duplicated entries for modalias of 'ieee1394:ven00000AACmo00000002sp0000A02Dver00010001' since entries for two devices below have the same parameters: * Acoustic Reality eAR Master One, Eroica, Figaro, and Ciaccona * TerraTec Aureon 7.1 FireWire I relied on FFADO revision 737 to add the former entry, on the other hand, the latter is based on message posted by actual user with information of sysfs node: * https://sourceforge.net/p/ffado/mailman/ffado-user/thread/5743F969.2080204%40marcobaldo.ch/ It appears that they have OUI of Terratec Electronic GmbH (0x000aac) and the same model ID, thus suffice to say that they have something common in their internals. Although it's not going to make a big difference, this commit arranges the entries.

el0_sync_compat+0x19c/0x1c0 The 'gpd_list_lock' is nominally named as such to protect the 'gpd_list' from concurrent access and mutation. Unfortunately, holding that mutex around various OPP framework calls leads to lockdep splats because now we're doing various operations in OPP core such as registering with debugfs while holding the list lock. We don't need to hold any list mutex while we're calling into OPP, so let's shrink the locking area of the 'gpd_list_lock' so that lockdep isn't triggered. This also helps reduce contention on this lock, which probably doesn't matter much but at least is nice to have.

powerpc/mm: Fix lockup on kernel exec fault
The powerpc kernel is not prepared to handle exec faults from kernel. Especially, the function is_exec_fault() will return 'false' when an exec fault is taken by kernel, because the check is based on reading current->thread.regs->trap which contains the trap from user. For instance, when provoking a LKDTM EXEC_USERSPACE test, current->thread.regs->trap is set to SYSCALL trap (0xc00), and the fault taken by the kernel is not seen as an exec fault by set_access_flags_filter().

nvme-tcp: can't set sk_user_data without write_lock
The sk_user_data pointer is supposed to be modified only while
holding the write_lock "sk_callback_lock", otherwise
we could race with other threads and crash the kernel.
we can't take the write_lock in nvmet_tcp_state_change()
because it would cause a deadlock, but the release_work queue
will set the pointer to NULL later so we can simply remove
the assignment.

Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctl
Even though we validate user-provided inputs we then traverse past
validated data when applying the new map. The issue was originally
discovered by Murray McAllister with this simple POC (if the following
is executed by an unprivileged user it will instantly panic the system):
int main(void) {
int fd, ret;
unsigned int buffer[10000];
fd = open("/dev/input/js0", O_RDONLY);
if (fd == -1)
printf("Error opening file\n");
ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
printf("%d\n", ret);
}
The solution is to traverse internal buffer which is guaranteed to only
contain valid date when constructing the map.

iov_iter: remove uaccess_kernel() warning from iov_iter_init()
This warning was there to catch any architectures that still use
CONFIG_SET_FS, and that would mis-use iov_iter_init() for anything that
wasn't a proper user space pointer. So that
WARN_ON_ONCE(uaccess_kernel());
makes perfect conceptual sense: you really shouldn't use a kernel
pointer with set_fs(KERNEL_DS) and then pass it to iov_iter_init().
HOWEVER.
Guenter Roeck reports that this warning actually triggers in no-mmu
configurations of both ARM and m68k. And the reason isn't that they
pass in a kernel pointer under set_fs(KERNEL_DS) at all: the reason is
that in those configurations, "uaccess_kernel()" is simply not reliable.
Those no-mmu setups set USER_DS and KERNEL_DS to the same values, so you
can't test for the difference.
In particular, the no-mmu case for ARM does
#define USER_DS KERNEL_DS
#define uaccess_kernel() (true)
so USER_DS and KERNEL_DS have the same value, and uaccess_kernel() is
always trivially true.
The m68k case is slightly different and not quite as obvious. It does
(spread out over multiple header files just to be extra exciting:
asm/processor.h, asm/segment.h and asm-generic/uaccess.h):
#define TASK_SIZE (0xFFFFFFFFUL)
#define USER_DS MAKE_MM_SEG(TASK_SIZE)
#define KERNEL_DS MAKE_MM_SEG(~0UL)
#define get_fs() (current_thread_info()->addr_limit)
#define uaccess_kernel() (get_fs().seg == KERNEL_DS.seg)
but the end result is the same: uaccess_kernel() will always be true,
because USER_DS and KERNEL_DS end up having the same value, even if that
value is defined differently.
This is very arguably a misfeature in those implementations, but in the
end we don't really care. All modern architectures have gotten rid of
set_fs() already, and generic kernel code never uses it. And while the
sanity check was a nice idea, an architecture would have to go the extra
mile to actually break this.
So this well-intentioned warning isn't really all that likely to find
anything but these known false positives, and as such just isn't worth
maintaining.

memblock, arm: fix crashes caused by holes in the memory map
The coordination between freeing of unused memory map, pfn_valid() and core mm assumptions about validity of the memory map in various ranges was not designed for complex layouts of the physical memory with a lot of holes all over the place.

A cleaner approach is to update ARM's implementation of pfn_valid() to take into accounting rounding of the freed memory map to pageblock boundaries and make sure it returns true for PFNs that have memory map entries even if there is no physical memory backing those PFNs.

cxl for 5.14
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions
- Define a device model for an HDM decoder tree
- Bridge CXL persistent memory capabilities to an NVDIMM bus /
device-model
- Switch to fine grained mapping of CXL MMIO registers to allow
different drivers / system software to own individual register blocks
- Enable media provisioning commands, and publish the label storage area
size in sysfs
- Miscellaneous cleanups and fixes

Merge tag 'cxl-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL (Compute Express Link) updates from Dan Williams:
"This subsystem is still in the build-out phase as the bulk of the
update is improvements to enumeration and fleshing out the device
model. In terms of new features, more mailbox commands have been added
to the allowed-list in support of persistent memory provisioning
support targeting v5.15.
The critical update from an enumeration perspective is support for the
CXL Fixed Memory Window Structure that indicates to Linux which system
physical address ranges decode to the CXL Host Bridges in the system.
This allows the driver to detect which address ranges have been mapped
by firmware and what address ranges are available for future hotplug.
So, again, mostly skeleton this round, with more meat targeting v5.15.
Summary:
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions
- Define a device model for an HDM decoder tree
- Bridge CXL persistent memory capabilities to an NVDIMM bus /

percpu: flush tlb in pcpu_reclaim_populated()
Prior to "percpu: implement partial chunk depopulation",
pcpu_depopulate_chunk() was called only on the destruction path. This
meant the virtual address range was on its way back to vmalloc which
will handle flushing the tlbs for us.
However, with pcpu_reclaim_populated(), we are now calling
pcpu_depopulate_chunk() during the active lifecycle of a chunk.
Therefore, we need to flush the tlb as well otherwise we can end up
accessing the wrong page through an invalid tlb mapping as reported in
[1].

csky: syscache: Fixup duplicate cache flush
The current csky logic of sys_cacheflush is wrong, it'll cause icache flush call dcache flush again. Now fixup it with a conditional "break & fallthrough". Fixes: |

exfat: handle wrong stream entry size in exfat_readdir()
The compatibility issue between linux exfat and exfat of some camera
company was reported from Florian. In their exfat, if the number of files
exceeds any limit, the DataLength in stream entry of the directory is
no longer updated. So some files created from camera does not show in
linux exfat. because linux exfat doesn't allow that cpos becomes larger
than DataLength of stream entry. This patch check DataLength in stream
entry only if the type is ALLOC_NO_FAT_CHAIN and add the check ensure
that dentry offset does not exceed max dentries size(256 MB) to avoid
the circular FAT chain issue.
