+Subject: block: rate-limit capacity change info log
+
+From: Li Chen <chenl311@chinatelecom.cn>
+
+commit 3179a5f7f86bcc3acd5d6fb2a29f891ef5615852 upstream.
+
+loop devices under heavy stress-ng loop streessor can trigger many
+capacity change events in a short time. Each event prints an info
+message from set_capacity_and_notify(), flooding the console and
+contributing to soft lockups on slow consoles.
+
+Switch the printk in set_capacity_and_notify() to
+pr_info_ratelimited() so frequent capacity changes do not spam
+the log while still reporting occasional changes.

+Subject: floppy: fix for PAGE_SIZE != 4KB
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Rene Rebe <rene@exactco.de>
+
+commit 82d20481024cbae2ea87fe8b86d12961bfda7169 upstream.
+
+For years I wondered why the floppy driver does not just work on
+sparc64, e.g:
+
+root@SUNW_375_0066:# disktype /dev/fd0
+disktype: Can't open /dev/fd0: No such device or address
+
+[  525.341906] disktype: attempt to access beyond end of device
+fd0: rw=0, sector=0, nr_sectors = 16 limit=8
+[  525.341991] floppy: error 10 while reading block 0
+
+Turns out floppy.c __floppy_read_block_0 tries to read one page for
+the first test read to determine the disk size and thus fails if that
+is greater than 4k. Adjust minimum MAX_DISK_SIZE to PAGE_SIZE to fix
+floppy on sparc64 and likely all other PAGE_SIZE != 4KB configs.

+Subject: fs/ntfs3: fix mount failure for sparse runs in run_unpack()
+
+From: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
+
+commit 801f614ba263cb37624982b27b4c82f3c3c597a9 upstream.
+
+Some NTFS volumes failed to mount because sparse data runs were not
+handled correctly during runlist unpacking. The code performed arithmetic
+on the special SPARSE_LCN64 marker, leading to invalid LCN values and
+mount errors.
+
+Add an explicit check for the case described above, marking the run as
+sparse without applying arithmetic.

+Subject: io_uring: fix filename leak in __io_openat_prep()
+
+From: Prithvi Tambewagh <activprithvi@gmail.com>
+
+commit b14fad555302a2104948feaff70503b64c80ac01 upstream.
+
+ __io_openat_prep() allocates a struct filename using getname(). However,
+for the condition of the file being installed in the fixed file table as
+well as having O_CLOEXEC flag set, the function returns early. At that
+point, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,
+the memory for the newly allocated struct filename is not cleaned up,
+causing a memory leak.
+
+Fix this by setting the REQ_F_NEED_CLEANUP for the request just after the
+successful getname() call, so that when the request is torn down, the
+filename will be cleaned up, along with other resources needing cleanup.

+Subject: kallsyms: Fix wrong "big" kernel symbol type read from procfs
+
+From: Zheng Yejian <zhengyejian@huaweicloud.com>
+
+commit f3f9f42232dee596d15491ca3f611d02174db49c upstream.
+
+Currently when the length of a symbol is longer than 0x7f characters,
+its type shown in /proc/kallsyms can be incorrect.
+
+I found this issue when reading the code, but it can be reproduced by
+following steps:
+
+  1. Define a function which symbol length is 130 characters:
+
+    #define X13(x) x##x##x##x##x##x##x##x##x##x##x##x##x
+    static noinline void X13(x123456789)(void)
+    {
+        printk("hello world\n");
+    }
+
+  2. The type in vmlinux is 't':
+
+    $ nm vmlinux | grep x123456
+    ffffffff816290f0 t x123456789x123456789x123456789x12[...]
+
+  3. Then boot the kernel, the type shown in /proc/kallsyms becomes 'g'
+     instead of the expected 't':
+
+    # cat /proc/kallsyms | grep x123456
+    ffffffff816290f0 g x123456789x123456789x123456789x12[...]
+
+The root cause is that, after commit 73bbb94466fd ("kallsyms: support
+"big" kernel symbols"), ULEB128 was used to encode symbol name length.
+That is, for "big" kernel symbols of which name length is longer than
+0x7f characters, the length info is encoded into 2 bytes.
+
+kallsyms_get_symbol_type() expects to read the first char of the
+symbol name which indicates the symbol type. However, due to the
+"big" symbol case not being handled, the symbol type read from
+/proc/kallsyms may be wrong, so handle it properly.

+Subject: lib/crypto: x86/blake2s: Fix 32-bit arg treated as 64-bit
+
+From: Eric Biggers <ebiggers@kernel.org>
+
+commit 2f22115709fc7ebcfa40af3367a508fbbd2f71e9 upstream.
+
+In the C code, the 'inc' argument to the assembly functions
+blake2s_compress_ssse3() and blake2s_compress_avx512() is declared with
+type u32, matching blake2s_compress().  The assembly code then reads it
+from the 64-bit %rcx.  However, the ABI doesn't guarantee zero-extension
+to 64 bits, nor do gcc or clang guarantee it.  Therefore, fix these
+functions to read this argument from the 32-bit %ecx.
+
+In theory, this bug could have caused the wrong 'inc' value to be used,
+causing incorrect BLAKE2s hashes.  In practice, probably not: I've fixed
+essentially this same bug in many other assembly files too, but there's
+never been a real report of it having caused a problem.  In x86_64, all
+writes to 32-bit registers are zero-extended to 64 bits.  That results
+in zero-extension in nearly all situations.  I've only been able to
+demonstrate a lack of zero-extension with a somewhat contrived example
+involving truncation, e.g. when the C code has a u64 variable holding
+0x1234567800000040 and passes it as a u32 expecting it to be truncated
+to 0x40 (64).  But that's not what the real code does, of course.

+Subject: mmc: sdhci-msm: Avoid early clock doubling during HS400 transition
+
+From: Sarthak Garg <sarthak.garg@oss.qualcomm.com>
+
+commit b1f856b1727c2eaa4be2c6d7cd7a8ed052bbeb87 upstream.
+
+According to the hardware programming guide, the clock frequency must
+remain below 52MHz during the transition to HS400 mode.
+
+However,in the current implementation, the timing is set to HS400 (a
+DDR mode) before adjusting the clock. This causes the clock to double
+prematurely to 104MHz during the transition phase, violating the
+specification and potentially resulting in CRC errors or CMD timeouts.
+
+This change ensures that clock doubling is avoided during intermediate
+transitions and is applied only when the card requires a 200MHz clock
+for HS400 operation.

+Subject: s390/dasd: Fix gendisk parent after copy pair swap
+
+From: Stefan Haberland <sth@linux.ibm.com>
+
+commit c943bfc6afb8d0e781b9b7406f36caa8bbf95cb9 upstream.
+
+After a copy pair swap the block device's "device" symlink points to
+the secondary CCW device, but the gendisk's parent remained the
+primary, leaving /sys/block/<dasdx> under the wrong parent.
+
+Move the gendisk to the secondary's device with device_move(), keeping
+the sysfs topology consistent after the swap.
