ARM: Defconfig changes for 5.14
A set of defconfig changes, we keep them in a separate branch to avoid conflicts between topics by separating them out. These changes are almost exclusively turning on new drivers for various platforms, or turning on modules for new drivers for the shared generic configs. -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAmDo3KoPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3L0IQAJEH7TmAZNlFuF3+wGBMgzzjN6grQ2goFLGZ 6vBLgP9os7hGR5Nj658z4g5JNUei/xs6od74KbbGq6Zj+B0Rk0DOa7bIfBTt5wxx sP+pJEYkZgkP0zoH5NQl7UBNfBFkojl1mBALgG60TUc2KHOgFlwBopljNdanvY7C o2xsQN8orZ1c6Ul2RqN5/rnwdyau9uTJ38WHjc0iR8z5vpZWWg29jhu2PXCFepBH rI6802UO7itJpH746tGnT4wVB3h6rr3k8PkouJxJE8NM1ei+B8ghV++qFVOZj98X jmf3SVonZI5xPtZypnK7h0YYxFb512DZCtNn0DaY74bEzswBpLxgg7M5eZzS1MFu LosJ+x00hzS8fFj/5JII9in2aNbfHRs1wMDXkGg1CXlv+viif42NCXR9PjtijzFt TzFPpYc9FoGYS5UZqdjBCOrUOe6aca8h8QyJD54Ry5e5uyH6Jm0C4Mu75UktnijO rj7v0/Mi6lSBoHbxIfGnQz/YAXyH1T7rRBJR1gSrFXi6TJJnMd8J81e6Ep+qdd/N UATrJyheCnGqtlNeqEYCLSeZWygDJ6O1vXgP2VXJqPEqTJr5aC2Tnq+aOVP/RnJ6 yXWVA9INgqP5ozN1mVqwvzymcMPRPGx/+uwLI+BtLEPngRRmXLh8PQ9s4qcbpXtm 6enhFGWv =8yuO -----END PGP SIGNATURE----- Merge tag 'arm-defconfig-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM defconfig updates from "Olof Johansson "A set of defconfig changes, we keep them in a separate branch to avoid conflicts between topics by separating them out.

ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the end
of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing legacy
mach/* include dependencies and moving platform detection/config to
drivers/soc. Also some updates/cleanup of platform data.
- Core power domain support for Tegra platforms, and some improvements
in build test coverage by adding stubs for compile test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip.

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: Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN is in RAM or not. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEeOVYVaWZL5900a/pOQOGJssO/ZEFAmDoctcTHHJwcHRAbGlu dXguaWJtLmNvbQAKCRA5A4Ymyw79kW1HCAC8lhm79EoktNw2+fumIfch15RjOGHC 8MfTSoPGJXLbwQXxBsTY8lGk8NRaLVRFDJ4OE8pMuwjCBbsgukg3oQUAbEt2n+zt DN4bCOV9vsunWs/w7S5xifFcNeeB3VqOjy2mFPaLpz3wj8fll+LtfghvHlXPyMSO xCO61F8AhsR4mUHeMmy5FRi0AG7fjYfaFrRYHqXQNAlnYqc3UgSSkfVViVEPeyOj TLefgjXkwCdrJ/84GRFkBqkXAz2vLNhic9BFt7YG2ZKbRDcAsQK5uqdmRR667edo Ca58NDOdsq3P2p+Qqum+JzWRc/F7/cGp+Twg+sA8sVvQ6Hr0TxmUNmsy =klV7 -----END PGP SIGNATURE----- Merge tag 'fixes-2021-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock Pull memblock fix from Mike Rapoport: "This is a fix for the rework of ARM's pfn_valid() implementation merged during this merge window.

Pull percpu fix from Dennis Zhou: "This is just a single change to fix percpu depopulation. The code relied on depopulation code written specifically for the free path and relied on vmalloc to do the tlb flush lazily. As we're modifying the backing pages during the lifetime of a chunk, we need to also flush the tlb accordingly. Guenter Roeck reported this issue in [1] on mips. I believe we just happen to be lucky given the much larger chunk sizes on x86 and consequently less churning of this memory" Link: https://lore.kernel.org/lkml/20210702191140.GA3166599@roeck-us.net/ [1] * 'for-5.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: flush tlb in pcpu_reclaim_populated() |

f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
such as allowing compression for mmap files, replacing the immutable bit with
internal bit to prohibits data writes explicitly, and adding a mount option,
"compress_cache", to improve random reads. And, we added "readonly" feature to
compact the partition w/ compression enabled, which will be useful for Android
RO partitions.
Enhancement:
- support compression for mmap file
- use an f2fs flag instead of IMMUTABLE bit for compression
- support RO feature w/ extent_cache
- fully support swapfile with file pinning
- improve atgc tunability
- add nocompress extensions to unselect files for compression
Bug fix:
- fix false alaram on iget failure during GC
- fix race condition on global pointers when there are multiple f2fs instances
- add MODULE_SOFTDEP for initramfs
As usual, we've also cleaned up some places for better code readability.
(e.g., sysfs/feature, debugging messages, slab cache name, and docs)

io_uring: remove dead non-zero 'poll' check
Colin reports that Coverity complains about checking for poll being non-zero after having dereferenced it multiple times. This is a valid complaint, and actually a leftover from back when this code was based on the aio poll code. Kill the redundant check.

io_uring: mitigate unlikely iopoll lag
We have requests like IORING_OP_FILES_UPDATE that don't go through ->iopoll_list but get completed in place under ->uring_lock, and so after dropping the lock io_iopoll_check() should expect that some CQEs might have get completed in a meanwhile. Currently such events won't be accounted in @nr_events, and the loop will continue to poll even if there is enough of CQEs. It shouldn't be a problem as it's not likely to happen and so, but not nice either. Just return earlier in this case, it should be enough.

powerpc/book3s64/mm: update flush_tlb_range to flush page walk cache
flush_tlb_range is special in that we don't specify the page size used for the translation. Hence when flushing TLB we flush the translation cache for all possible page sizes. The kernel also uses the same interface when moving page tables around. Such a move requires us to flush the page walk cache. Instead of adding another interface to force page walk cache flush, update flush_tlb_range to flush page walk cache if the range flushed is more than the PMD range. A page table move will always involve an invalidate range more than PMD_SIZE. Running microbenchmark with mprotect and parallel memory access didn't show any observable performance impact.

mm/mremap: allow arch runtime override
Patch series "Speedup mremap on ppc64", v8. This patchset enables MOVE_PMD/MOVE_PUD support on power. This requires the platform to support updating higher-level page tables without updating page table entries. This also needs to invalidate the Page Walk Cache on architecture supporting the same. This patch (of 3): Architectures like ppc64 support faster mremap only with radix translation. Hence allow a runtime check w.r.t support for fast mremap.

mm/mremap: hold the rmap lock in write mode when moving page table entries.
To avoid a race between rmap walk and mremap, mremap does take_rmap_locks(). The lock was taken to ensure that rmap walk don't miss a page table entry due to PTE moves via move_pagetables(). The kernel does further optimization of this lock such that if we are going to find the newly added vma after the old vma, the rmap lock is not taken. This is because rmap walk would find the vmas in the same order and if we don't find the page table attached to older vma we would find it with the new vma which we would iterate later. As explained in commit |

mm/mremap: use pmd/pud_poplulate to update page table entries
pmd/pud_populate is the right interface to be used to set the respective page table entries. Some architectures like ppc64 do assume that set_pmd/pud_at can only be used to set a hugepage PTE. Since we are not setting up a hugepage PTE here, use the pmd/pud_populate interface.

scripts/decode_stacktrace.sh: indicate 'auto' can be used for base path
Add "auto" to the usage message so that it's a little clearer that you can pass "auto" as the second argument. When passing "auto" the script tries to find the base path automatically instead of requiring it be passed on the commandline. Also use [<variable>] to indicate the variable argument and that it is optional so that we can differentiate from the literal "auto" that should be passed.

scripts/decode_stacktrace.sh: support debuginfod
Now that stacktraces contain the build ID information we can update this script to use debuginfod-find to locate the debuginfo for the vmlinux and modules automatically. This can replace the existing code that requires specifying a path to vmlinux or tries to find the vmlinux and modules automatically by using the release number. Work it into the script as a fallback option if the vmlinux isn't specified on the commandline.

module: add printk formats to add module build ID to stacktraces
Let's make kernel stacktraces easier to identify by including the build ID[1] of a module if the stacktrace is printing a symbol from a module. This makes it simpler for developers to locate a kernel module's full debuginfo for a particular stacktrace. Combined with scripts/decode_stracktrace.sh, a developer can download the matching debuginfo from a debuginfod[2] server and find the exact file and line number for the functions plus offsets in a stacktrace that match the module. This is especially useful for pstore crash debugging where the kernel crashes are recorded in something like console-ramoops and the recovery kernel/modules are different or the debuginfo doesn't exist on the device due to space concerns (the debuginfo can be too large for space limited devices). Originally, I put this on the %pS format, but that was quickly rejected given that %pS is used in other places such as ftrace where build IDs aren't meaningful. There was some discussions on the list to put every module build ID into the "Modules linked in:" section of the stacktrace message but that quickly becomes very hard to read once you have more than three or four modules linked in. It also provides too much information when we don't expect each module to be traversed in a stacktrace. Having the build ID for modules that aren't important just makes things messy. Splitting it to multiple lines for each module quickly explodes the number of lines printed in an oops too, possibly wrapping the warning off the console. And finally, trying to stash away each module used in a callstack to provide the ID of each symbol printed is cumbersome and would require changes to each architecture to stash away modules and return their build IDs once unwinding has completed. Instead, we opt for the simpler approach of introducing new printk formats '%pS[R]b' for "pointer symbolic backtrace with module build ID" and '%pBb' for "pointer backtrace with module build ID" and then updating the few places in the architecture layer where the stacktrace is printed to use this new format.

dump_stack: add vmlinux build ID to stack traces
Add the running kernel's build ID[1] to the stacktrace information header. This makes it simpler for developers to locate the vmlinux with full debuginfo for a particular kernel stacktrace. Combined with scripts/decode_stracktrace.sh, a developer can download the correct vmlinux from a debuginfod[2] server and find the exact file and line number for the functions plus offsets in a stacktrace. This is especially useful for pstore crash debugging where the kernel crashes are recorded in the pstore logs and the recovery kernel is different or the debuginfo doesn't exist on the device due to space concerns (the data can be large and a security concern). The stacktrace can be analyzed after the crash by using the build ID to find the matching vmlinux and understand where in the function something went wrong. Example stacktrace from lkdtm: WARNING: CPU: 4 PID: 3255 at drivers/misc/lkdtm/bugs.c:83 lkdtm_WARNING+0x28/0x30 [lkdtm] Modules linked in: lkdtm rfcomm algif_hash algif_skcipher af_alg xt_cgroup uinput xt_MASQUERADE CPU: 4 PID: 3255 Comm: bash Not tainted 5.11 #3 aa23f7a1231c229de205662d5a9e0d4c580f19a1 Hardware name: Google Lazor (rev3+) with KB Backlight (DT) pstate: 00400009 (nzcv daif +PAN -UAO -TCO BTYPE=--) pc : lkdtm_WARNING+0x28/0x30 [lkdtm] The hex string aa23f7a1231c229de205662d5a9e0d4c580f19a1 is the build ID, following the kernel version number.
