kbuild/mkspec: fix grub2 installkernel issue

2016-04-12T16:09:00+00:00

commit c8b08ca558c0067bc9e15ce3f1e70af260410bb2 upstream.

mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

scripts/kconfig: allow building with make 3.80 again

2016-04-12T16:09:00+00:00

commit 42f9d3c6888bceef6dc7ba72c77acf47347dcf05 upstream.

Documentation/Changes still lists this as the minimal required version,
so it ought to remain usable for the time being.

ld-version: Fix awk regex compile failure

2016-03-16T15:43:01+00:00

commit 4b7b1ef2c2f83d702272555e8adb839a50ba0f8e upstream.

The ld-version.sh script fails on some versions of awk with the
following error, resulting in build failures for MIPS:

awk: scripts/ld-version.sh: line 4: regular expression compile failed (missing '(')

This is due to the regular expression ".*)", meant to strip off the
beginning of the ld version string up to the close bracket, however
brackets have a meaning in regular expressions, so lets escape it so
that awk doesn't expect a corresponding open bracket.

commit a7df4716d19594b7b3f106f0bc0ca1c548e508e6 upstream.

Similarly to commit fb1770aa78a43530940d0c2dd161e77bc705bdac, with gcc 5
on Ubuntu and CONFIG_STATIC_LINK=y I was seeing these linker errors:

/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/librt.a(timer_create.o): In function `__timer_create_new':

Obviously we also need -lpthread for librt.a.

scripts/bloat-o-meter: fix python3 syntax error

2016-02-25T20:01:22+00:00

commit 72214a24a7677d4c7501eecc9517ed681b5f2db2 upstream.

In Python3+ print is a function so the old syntax is not correct
anymore:

  $ ./scripts/bloat-o-meter vmlinux.o vmlinux.o.old
    File "./scripts/bloat-o-meter", line 61
      print "add/remove: %s/%s grow/shrink: %s/%s up/down: %s/%s (%s)" % \
                                                                     ^
  SyntaxError: invalid syntax

Fix by calling print as a function.

scripts/recordmcount.pl: support data in text section on powerpc

2016-01-31T19:29:03+00:00

commit 2e50c4bef77511b42cc226865d6bc568fa7f8769 upstream.

If a text section starts out with a data blob before the first
function start label, disassembly parsing doing in recordmcount.pl
gets confused on powerpc, leading to creation of corrupted module
objects.

This was not a problem so far since the compiler would never create
such text sections.  However, this has changed with a recent change
in GCC 6 to support distances of > 2GB between a function and its
assoicated TOC in the ELFv2 ABI, exposing this problem.

There is already code in recordmcount.pl to handle such data blobs
on the sparc64 platform.  This patch uses the same method to handle
those on powerpc as well.

ftrace/scripts: Have recordmcount copy the object file

2015-12-16T20:46:07+00:00

Russell King found that he had weird side effects when compiling the kernel
with hard linked ccache. The reason was that recordmcount modified the
kernel in place via mmap, and when a file gets modified twice by
recordmcount, it will complain about it. To fix this issue, Russell wrote a
patch that checked if the file was hard linked more than once and would
unlink it if it was.

Linus Torvalds was not happy with the fact that recordmcount does this in
place modification. Instead of doing the unlink only if the file has two or
more hard links, it does the unlink all the time. In otherwords, it always
does a copy if it changed something. That is, it does the write out if a
change was made.

scripts: recordmcount: break hardlinks

2015-12-16T14:28:23+00:00

recordmcount edits the file in-place, which can cause problems when
using ccache in hardlink mode.  Arrange for recordmcount to break a
hardlinked object.
