ld-version: Fix awk regex compile failure

2016-03-22T15:10:35Z

[ Upstream commit 4b7b1ef2c2f83d702272555e8adb839a50ba0f8e ] 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.

recordmcount: Fix endianness handling bug for nop_mcount

2016-01-31T19:23:40Z

commit c84da8b9ad3761eef43811181c7e896e9834b26b upstream. In nop_mcount, shdr->sh_offset and welp->r_offset should handle endianness properly, otherwise it will trigger Segmentation fault if the recordmcount main and file.o have different endianness.

recordmcount: arm64: Replace the ignored mcount call into nop

2016-01-31T19:23:39Z

commit 2ee8a74f2a5da913637f75a19a0da0e7a08c0f86 upstream. By now, the recordmcount only records the function that in following sections: .text/.ref.text/.sched.text/.spinlock.text/.irqentry.text/ .kprobes.text/.text.unlikely For the function that not in these sections, the call mcount will be in place and not be replaced when kernel boot up. And it will bring performance overhead, such as do_mem_abort (in .exception.text section). This patch make the call mcount to nop for this case in recordmcount.

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

2016-01-31T19:23:38Z

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.

localmodconfig: Use Kbuild files too

2015-09-13T16:07:40Z

commit c0ddc8c745b7f89c50385fd7aa03c78dc543fa7a upstream. In kbuild it is allowed to define objects in files named "Makefile" and "Kbuild". Currently localmodconfig reads objects only from "Makefile"s and misses modules like nouveau.

scripts/gdb: fix lx-lsmod refcnt

2015-05-29T01:25:19Z

Commit 2f35c41f58a9 ("module: Replace module_ref with atomic_t refcnt") changes the way refcnt is handled but did not update the gdb script to use the new variable. Since refcnt is not per-cpu anymore, we can directly read its value.
