      profiling: remove profile=sleep support · b88f5538
      Tetsuo Handa authored
      The kernel sleep profile is no longer working due to a recursive locking
      bug introduced by commit 42a20f86 ("sched: Add wrapper for get_wchan()
      to keep task blocked")
      
      Booting with the 'profile=sleep' kernel command line option added or
      executing
      
        # echo -n sleep > /sys/kernel/profiling
      
      after boot causes the system to lock up.
      
      Lockdep reports
      
        kthreadd/3 is trying to acquire lock:
        ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: get_wchan+0x32/0x70
      
        but task is already holding lock:
        ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: try_to_wake_up+0x53/0x370
      
      with the call trace being
      
         lock_acquire+0xc8/0x2f0
         get_wchan+0x32/0x70
         __update_stats_enqueue_sleeper+0x151/0x430
         enqueue_entity+0x4b0/0x520
         enqueue_task_fair+0x92/0x6b0

         complete+0x2f/0x40
         kthread+0xfb/0x180
      
      However, since nobody noticed this regression for more than two years,
      let's remove 'profile=sleep' support based on the assumption that nobody
      needs this functionality.

      Pull x86 fixes from Thomas Gleixner:
      
       - Prevent a deadlock on cpu_hotplug_lock in the aperf/mperf driver.
      
         A recent change in the ACPI code which consolidated code pathes moved
         the invocation of init_freq_invariance_cppc() to be moved to a CPU
         hotplug handler. The first invocation on AMD CPUs ends up enabling a
         static branch which dead locks because the static branch enable tries
         to acquire cpu_hotplug_lock but that lock is already held write by
         the hotplug machinery.
      
         Use static_branch_enable_cpuslocked() instead and take the hotplug
         lock read for the Intel code path which is invoked from the
         architecture code outside of the CPU hotplug operations.
      
       - Fix the number of reserved bits in the sev_config structure bit field
         so that the bitfield does not exceed 64 bit.
      
       - Add missing Zen5 model numbers
      
       - Fix the alignment assumptions of pti_clone_pgtable() and
         clone_entry_text() on 32-bit:
      
         The code assumes PMD aligned code sections, but on 32-bit the kernel
         entry text is not PMD aligned. So depending on the code size and
         location, which is configuration and compiler dependent, entry text
         can cross a PMD boundary. As the start is not PMD aligned adding PMD
         size to the start address is larger than the end address which
         results in partially mapped entry code for user space. That causes
         endless recursion on the first entry from userspace (usually #PF).
      
         Cure this by aligning the start address in the addition so it ends up
         at the next PMD start address.
      
         clone_entry_text() enforces PMD mapping, but on 32-bit the tail might
         eventually be PTE mapped, which causes a map fail because the PMD for
         the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for
         the clone() invocation which resolves to PTE on 32-bit and PMD on
         64-bit.
      
       - Zero the 8-byte case for get_user() on range check failure on 32-bit
      
         The recend consolidation of the 8-byte get_user() case broke the
         zeroing in the failure case again. Establish it by clearing ECX
         before the range check and not afterwards as that obvioulsy can't be
         reached when the range check fails

      Pull timer fixes from Thomas Gleixner:
       "Two fixes for the timer/clocksource code:
      
         - The recent fix to make the take over of the broadcast timer more
           reliable retrieves a per CPU pointer in preemptible context.
      
           This went unnoticed in testing as some compilers hoist the access
           into the non-preemotible section where the pointer is actually
           used, but obviously compilers can rightfully invoke it where the
           code put it.
      
           Move it into the non-preemptible section right to the actual usage
           side to cure it.
      
         - The clocksource watchdog is supposed to emit a warning when the
           retry count is greater than one and the number of retries reaches
           the limit.
      
           The condition is backwards and warns always when the count is
           greater than one. Fixup the condition to prevent spamming dmesg"

      Pull scheduler fixes from Thomas Gleixner:
      
       - When stime is larger than rtime due to accounting imprecision, then
         utime = rtime - stime becomes negative. As this is unsigned math, the
         result becomes a huge positive number.
      
         Cure it by resetting stime to rtime in that case, so utime becomes 0.
      
       - Restore consistent state when sched_cpu_deactivate() fails.
      
         When offlining a CPU fails in sched_cpu_deactivate() after the SMT
         present counter has been decremented, then the function aborts but
         fails to increment the SMT present counter and leaves it imbalanced.
         Consecutive operations cause it to underflow. Add the missing fixup
         for the error path.
      
         For SMT accounting the runqueue needs to marked online again in the
         error exit path to restore consistent state.

      Rob Herring (Arm) authored
      Commit 04f08ef2 ("arm/arm64: dts: arm: Use generic clock and
      regulator nodenames") renamed nodes and created 2 "clock-24000000" nodes
      (at different paths).
      
      The kernel can't handle these duplicate names even though they are at
      different paths.  Fix this by renaming one of the nodes to "clock-pclk".
      
      This name is aligned with other Arm boards (those didn't have a known
      frequency to use in the node name).

      Paulo Alcantara authored
      NetApp server requires the file to be open with FILE_READ_EA access in
      order to support FSCTL_GET_REPARSE_POINT, otherwise it will return
      STATUS_INVALID_DEVICE_REQUEST.  It doesn't make any sense because
      there's no requirement for FILE_READ_EA bit to be set nor
      STATUS_INVALID_DEVICE_REQUEST being used for something other than
      "unsupported reparse points" in MS-FSA.
      
      To fix it and improve compatibility, set FILE_READ_EA & SYNCHRONIZE
      bits to match what Windows client currently does.

      arm64: jump_label: Ensure patched jump_labels are visible to all CPUs · cfb00a35
      Will Deacon authored
      Although the Arm architecture permits concurrent modification and
      execution of NOP and branch instructions, it still requires some
      synchronisation to ensure that other CPUs consistently execute the newly
      written instruction:
      
       >  When the modified instructions are observable, each PE that is
       >  executing the modified instructions must execute an ISB or perform a
       >  context synchronizing event to ensure execution of the modified
       >  instructions
      
      Prior to commit f6cc0c50 ("arm64: Avoid calling stop_machine() when
      patching jump labels"), the arm64 jump_label patching machinery
      performed synchronisation using stop_machine() after each modification,
      however this was problematic when flipping static keys from atomic
      contexts (namely, the arm_arch_timer CPU hotplug startup notifier) and
      so we switched to the _nosync() patching routines to avoid "scheduling
      while atomic" BUG()s during boot.
      
      In hindsight, the analysis of the issue in f6cc0c50 isn't quite
      right: it cites the use of IPIs in the default patching routines as the
      cause of the lockup, whereas stop_machine() does not rely on IPIs and
      the I-cache invalidation is performed using __flush_icache_range(),
      which elides the call to kick_all_cpus_sync(). In fact, the blocking
      wait for other CPUs is what triggers the BUG() and the problem remains
      even after f6cc0c50, for example because we could block on the
      jump_label_mutex. Eventually, the arm_arch_timer driver was fixed to
      avoid the static key entirely in commit a862fc22
      ("clocksource/arm_arch_timer: Remove use of workaround static key").
      
      This all leaves the jump_label patching code in a funny situation on
      arm64 as we do not synchronise with other CPUs to reduce the likelihood
      of a bug which no longer exists. Consequently, toggling a static key on
      one CPU cannot be assumed to take effect on other CPUs, leading to
      potential issues, for example with missing preempt notifiers.
      
      Rather than revert f6cc0c50 and go back to stop_machine() for each
      patch site, implement arch_jump_label_transform_apply() and kick all
      the other CPUs with an IPI at the end of patching.

      syscalls: fix syscall macros for newfstat/newfstatat · 343416f0
      Arnd Bergmann authored
      The __NR_newfstat and __NR_newfstatat macros accidentally got renamed
      in the conversion to the syscall.tbl format, dropping the 'new' portion
      of the name.
      
      In an unrelated change, the two syscalls are no longer architecture
      specific but are once more defined on all 64-bit architectures, so the
      'newstat' ABI keyword can be dropped from the table as a simplification.

      uretprobe: change syscall number, again · 54233a42
      Arnd Bergmann authored
      Despite multiple attempts to get the syscall number assignment right
      for the newly added uretprobe syscall, we ended up with a bit of a mess:
      
       - The number is defined as 467 based on the assumption that the
         xattrat family of syscalls would use 463 through 466, but those
         did not make it into 6.11.
      
       - The include/uapi/asm-generic/unistd.h file still lists the number
         463, but the new scripts/syscall.tbl that was supposed to have the
         same data lists 467 instead as the number for arc, arm64, csky,
         hexagon, loongarch, nios2, openrisc and riscv. None of these
         architectures actually provide a uretprobe syscall.
      
       - All the other architectures (powerpc, arm, mips, ...) don't list
         this syscall at all.
      
      There are two ways to make it consistent again: either list it with
      the same syscall number on all architectures, or only list it on x86
      but not in scripts/syscall.tbl and asm-generic/unistd.h.
      
      Based on the most recent discussion, it seems like we won't need it
      anywhere else, so just remove the inconsistent assignment and instead
      move the x86 number to the next available one in the architecture
      specific range, which is 335.
