      arm64: dts: qcom: Remove duplicate sc7180-trogdor include on lazor/homestar · 372b2aee
      Stephen Boyd authored
      The sc7180-trogdor-{lazor,homestar}-*.dtsi files all include
      sc7180-trogdor.dtsi and sc7180-trogdor-lazor.dtsi or
      sc7180-trogdor-homestar.dtsi, so including it here in the
      sc7180-trogdor-{lazor,homestar}.dtsi file means we have a duplicate
      include after commit 19794489 ("arm64: dts: qcom: Only include
      sc7180.dtsi in sc7180-trogdor.dtsi"). We include the sc7180-trogdor.dtsi
      file in a board like sc7180-trogdor-lazor-r1.dts so that we can include
      the display bridge snippet (e.g. sc7180-trogdor-ti-sn65dsi86.dtsi)
      instead of making ever increasing variants like
      sc7180-trogdor-lazor-ti-sn65dsi86.dtsi.
      
      Unfortunately, having the double include like this means the display
      bridge's i2c bus is left disabled instead of enabled by the bridge
      snippet. Any boards that use the i2c bus for the display bridge will
      have the bus disabled when we include sc7180-trogdor.dtsi the second
      time, which picks up the i2c status="disabled" line from sc7180.dtsi.
      This leads to the display not turning on and black screens at boot on
      lazor and homestar devices.
      
      Fix this by dropping the include and making a note that the
      sc7180-trogdor-{lazor,homestar}.dtsi file must be included after
      sc7180-trogdor.dtsi

      bluetooth: don't use bitmaps for random flag accesses · e1cff700
      Linus Torvalds authored
      The bluetooth code uses our bitmap infrastructure for the two bits (!)
      of connection setup flags, and in the process causes odd problems when
      it converts between a bitmap and just the regular values of said bits.
      
      It's completely pointless to do things like bitmap_to_arr32() to convert
      a bitmap into a u32.  It shoudln't have been a bitmap in the first
      place.  The reason to use bitmaps is if you have arbitrary number of
      bits you want to manage (not two!), or if you rely on the atomicity
      guarantees of the bitmap setting and clearing.
      
      The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
      clear the bit values, but considering that it then copies the bitmaps
      around with "bitmap_to_arr32()" and friends, there clearly cannot be a
      lot of atomicity requirements.
      
      So just use a regular integer.
      
      In the process, this avoids the warnings about erroneous use of
      bitmap_from_u64() which were triggered on 32-bit architectures when
      conversion from a u64 would access two words (and, surprise, surprise,
      only one word is needed - and indeed overkill - for a 2-bit bitmap).
      
      That was always problematic, but the compiler seems to notice it and
      warn about the invalid pattern only after commit 0a97953f ("lib: add
      bitmap_{from,to}_arr64") changed the exact implementation details of
      'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

      It used to grab an extra reference to struct file rather than

      modpost: simplify mod->name allocation · 8c9ce89c
      Masahiro Yamada authored
      mod->name is set to the ELF filename with the suffix ".o" stripped.
      
      The current code calls strdup() and free() to manipulate the string,
      but a simpler approach is to pass new_module() with the name length
      subtracted by 2.
      
      Also, check if the passed filename ends with ".o" before stripping it.
      
      The current code blindly chops the suffix:
      
          tmp[strlen(tmp) - 2] = '\0'
      
      It will cause buffer under-run if strlen(tmp) < 2;

      kbuild: factor out the common objtool arguments · b42d2306
      Masahiro Yamada authored
      scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups
      for the objtool arguments.
      
      It was difficult to factor out them because all the vmlinux build rules
      were written in a shell script. It is somewhat tedious to touch the two
      files every time a new objtool option is supported.
      
      To reduce the code duplication, move the objtool for vmlinux.o into
      scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib
      so they are shared between Makefile.build and Makefile.vmlinux_o.

      kbuild: clean .tmp_* pattern by make clean · b0d6207b
      Masahiro Yamada authored
      Change the "make clean" rule to remove all the .tmp_* files.
      
      .tmp_objdiff is the only exception, which should be removed by
      "make mrproper".
      
      Rename the record directory of objdiff, .tmp_objdiff to .objdiff to
      avoid the removal by "make clean".
