        It should be all totally risk-free, of course. :-)
      
         - Fix out-of-spec hardware (1st gen Hygon) which does not implement
           MSR_AMD64_SEV even though the spec clearly states so, and check
           CPUID bits first.
      
         - Send only one signal to a task when it is a SEGV_PKUERR si_code
           type.
      
         - Do away with all the wankery of reserving X amount of memory in the
           first megabyte to prevent BIOS corrupting it and simply and
           unconditionally reserve the whole first megabyte.
      
         - Make alternatives NOP optimization work at an arbitrary position
           within the patched sequence because the compiler can put
           single-byte NOPs for alignment anywhere in the sequence (32-bit
           retpoline), vs our previous assumption that the NOPs are only
           appended.
      
         - Force-disable ENQCMD[S] instructions support and remove
           update_pasid() because of insufficient protection against FPU state
           modification in an interrupt context, among other xstate horrors
           which are being addressed at the moment. This one limits the
           fallout until proper enablement.
      
         - Use cpu_feature_enabled() in the idxd driver so that it can be
           build-time disabled through the defines in disabled-features.h.
      
         - Fix LVT thermal setup for SMI delivery mode by making sure the APIC
           LVT value is read before APIC initialization so that softlockups
           during boot do not happen at least on one machine.
      
         - Mark all legacy interrupts as legacy vectors when the IO-APIC is
           disabled and when all legacy interrupts are routed through the PIC"

      ext4: fix no-key deletion for encrypt+casefold · 63e7f128
      Daniel Rosenberg authored
      commit 471fbbea ("ext4: handle casefolding with encryption") is
      missing a few checks for the encryption key which are needed to
      support deleting enrypted casefolded files when the key is not
      present.
      
      This bug made it impossible to delete encrypted+casefolded directories
      without the encryption key, due to errors like:
      
          W         : EXT4-fs warning (device vdc): __ext4fs_dirhash:270: inode #49202: comm Binder:378_4: Siphash requires key
      
      Repro steps in kvm-xfstests test appliance:
            mkfs.ext4 -F -E encoding=utf8 -O encrypt /dev/vdc
            mount /vdc
            mkdir /vdc/dir
            chattr +F /vdc/dir
            keyid=$(head -c 64 /dev/zero | xfs_io -c add_enckey /vdc | awk '{print $NF}')
            xfs_io -c "set_encpolicy $keyid" /vdc/dir
            for i in `seq 1 100`; do
                mkdir /vdc/dir/$i
            done
            xfs_io -c "rm_enckey $keyid" /vdc
            rm -rf /vdc/dir # fails with the bug

      ext4: fix memory leak in ext4_fill_super · afd09b61
      Alexey Makhalov authored
      Buffer head references must be released before calling kill_bdev();
      otherwise the buffer head (and its page referenced by b_data) will not
      be freed by kill_bdev, and subsequently that bh will be leaked.
      
      If blocksizes differ, sb_set_blocksize() will kill current buffers and
      page cache by using kill_bdev(). And then super block will be reread
      again but using correct blocksize this time. sb_set_blocksize() didn't
      fully free superblock page and buffer head, and being busy, they were
      not freed and instead leaked.
      
      This can easily be reproduced by calling an infinite loop of:
      
        systemctl start <ext4_on_lvm>.mount, and
        systemctl stop <ext4_on_lvm>.mount
      
      ... since systemd creates a cgroup for each slice which it mounts, and
      the bh leak get amplified by a dying memory cgroup that also never
      gets freed, and memory consumption is much more easily noticed.
      
      Fixes: ce40733c ("ext4: Check for return value from sb_set_blocksize")
      Fixes: ac27a0ec ("ext4: initial copy of files from ext3")

      ext4: fix fast commit alignment issues · a7ba36bc
      Harshad Shirwadkar authored
      Fast commit recovery data on disk may not be aligned. So, when the
      recovery code reads it, this patch makes sure that fast commit info
      found on-disk is first memcpy-ed into an aligned variable before
      accessing it. As a consequence of it, we also remove some macros that
      could resulted in unaligned accesses.

      "I see. Now I understand your patch. Honestly, seeing how fragile is trying
      to fix extent tree after split has failed in the middle, I would probably
      go even further and make sure we fix the tree properly in case of ENOSPC
      and EDQUOT (those are easily user triggerable).  Anything else indicates a
      HW problem or fs corruption so I'd rather leave the extent tree as is and
      don't try to fix it (which also means we will not create overlapping
      extents)."
