      lib/devres.c, which implements devm_ioremap_resource(), is only built
      when CONFIG_HAS_IOMEM is set/enabled, so MTD_HYPERBUS should depend

      cifs: replace various strncpy with strscpy and similar · 340625e6
      Ronnie Sahlberg authored
      
      
      Using strscpy is cleaner, and avoids some problems with
      handling maximum length strings.  Linus noticed the
      original problem and Aurelien pointed out some additional
      problems. Fortunately most of this is SMB1 code (and
      in particular the ASCII string handling older, which
      is less common).

      kallsyms: Don't let kallsyms_lookup_size_offset() fail on retrieving the first symbol · 2a1a3fa0
      Marc Zyngier authored
      An arm64 kernel configured with
      
        CONFIG_KPROBES=y
        CONFIG_KALLSYMS=y
        # CONFIG_KALLSYMS_ALL is not set
        CONFIG_KALLSYMS_BASE_RELATIVE=y
      
      reports the following kprobe failure:
      
        [    0.032677] kprobes: failed to populate blacklist: -22
        [    0.033376] Please take care of using kprobes.
      
      It appears that kprobe fails to retrieve the symbol at address
      0xffff000010081000, despite this symbol being in System.map:
      
        ffff000010081000 T __exception_text_start
      
      This symbol is part of the first group of aliases in the
      kallsyms_offsets array (symbol names generated using ugly hacks in
      scripts/kallsyms.c):
      
        kallsyms_offsets:
                .long   0x1000 // do_undefinstr
                .long   0x1000 // efi_header_end
                .long   0x1000 // _stext
                .long   0x1000 // __exception_text_start
                .long   0x12b0 // do_cp15instr
      
      Looking at the implementation of get_symbol_pos(), it returns the
      lowest index for aliasing symbols. In this case, it return 0.
      
      But kallsyms_lookup_size_offset() considers 0 as a failure, which
      is obviously wrong (there is definitely a valid symbol living there).
      In turn, the kprobe blacklisting stops abruptly, hence the original
      error.
      
      A CONFIG_KALLSYMS_ALL kernel wouldn't fail as there is always
      some random symbols at the beginning of this array, which are never
      looked up via kallsyms_lookup_size_offset.
      
      Fix it by considering that get_symbol_pos() is always successful
      (which is consistent with the other uses of this function).

      NFSv2: Fix write regression · d33d4beb

      Ensure we update the write result count on success, since the
      RPC call itself does not do so.

      NFSv2: Fix eof handling · 71affe9b
      Trond Myklebust authored
      
      
      If we received a reply from the server with a zero length read and
      no error, then that implies we are at eof.

      mfd: rk808: Mark pm functions __maybe_unused · 5752bc43
      Arnd Bergmann authored
      The newly added suspend/resume functions are only used if CONFIG_PM
      is enabled:
      
      drivers/mfd/rk808.c:752:12: error: 'rk8xx_resume' defined but not used [-Werror=unused-function]
      drivers/mfd/rk808.c:732:12: error: 'rk8xx_suspend' defined but not used [-Werror=unused-function]
      
      Mark them as __maybe_unused so the compiler can silently drop them
      when they are not needed.
