+Subject: ALSA: intel_hdmi: Fix off-by-one error in __hdmi_lpe_audio_probe()
+
+From: Thorsten Blum <thorsten.blum@linux.dev>
+
+commit 8cbe564974248ee980562be02f2b1912769562c7 upstream.
+
+In __hdmi_lpe_audio_probe(), strscpy() is incorrectly called with the
+length of the source string (excluding the NUL terminator) rather than
+the size of the destination buffer. This results in one character less
+being copied from 'card->shortname' to 'pcm->name'.
+
+Use the destination buffer size instead to ensure the card name is
+copied correctly.
+
+Cc: stable@vger.kernel.org

+Subject: KVM: VMX: Allow guest to set DEBUGCTL.RTM_DEBUG if RTM is supported
+
+From: Sean Christopherson <seanjc@google.com>
+
+commit 17ec2f965344ee3fd6620bef7ef68792f4ac3af0 upstream.
+
+Let the guest set DEBUGCTL.RTM_DEBUG if RTM is supported according to the
+guest CPUID model, as debug support is supposed to be available if RTM is
+supported, and there are no known downsides to letting the guest debug RTM
+aborts.
+
+Note, there are no known bug reports related to RTM_DEBUG, the primary
+motivation is to reduce the probability of breaking existing guests when a
+future change adds a missing consistency check on vmcs12.GUEST_DEBUGCTL
+(KVM currently lets L2 run with whatever hardware supports; whoops).
+
+Note #2, KVM already emulates DR6.RTM, and doesn't restrict access to
+DR7.RTM.

+Subject: MIPS: mm: tlb-r4k: Uniquify TLB entries on init
+
+From: Jiaxun Yang <jiaxun.yang@flygoat.com>
+
+commit 35ad7e181541aa5757f9f316768d3e64403ec843 upstream.
+
+Hardware or bootloader will initialize TLB entries to any value, which
+may collide with kernel's UNIQUE_ENTRYHI value. On MIPS microAptiv/M5150
+family of cores this will trigger machine check exception and cause boot
+failure. On M5150 simulation this could happen 7 times out of 1000 boots.
+
+Replace local_flush_tlb_all() with r4k_tlb_uniquify() which probes each
+TLB ENTRIHI unique value for collisions before it's written, and in case
+of collision try a different ASID.

+Subject: mm/hmm: move pmd_to_hmm_pfn_flags() to the respective #ifdeffery
+
+From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
+
+commit 188cb385bbf04d486df3e52f28c47b3961f5f0c0 upstream.
+
+When pmd_to_hmm_pfn_flags() is unused, it prevents kernel builds with
+clang, `make W=1` and CONFIG_TRANSPARENT_HUGEPAGE=n:
+
+ mm/hmm.c:186:29: warning: unused function 'pmd_to_hmm_pfn_flags' [-Wunused-function]
+
+Fix this by moving the function to the respective existing ifdeffery
+for its the only user.
+

+
+From: Tao Xue <xuetao09@huawei.com>
+
+commit 151c0aa896c47a4459e07fee7d4843f44c1bb18e upstream.
+
+1. In func configfs_composite_bind() -> composite_os_desc_req_prepare():
+if kmalloc fails, the pointer cdev->os_desc_req will be freed but not
+set to NULL. Then it will return a failure to the upper-level function.
+2. in func configfs_composite_bind() -> composite_dev_cleanup():
+it will checks whether cdev->os_desc_req is NULL. If it is not NULL, it
+will attempt to use it.This will lead to a use-after-free issue.
+
