ftrace/recordmcount: Work around for addition of metag magic but not relocations

2016-08-20T16:09:23+00:00

commit b2e1c26f0b62531636509fbcb6dab65617ed8331 upstream. glibc recently did a sync up (94e73c95d9b5 "elf.h: Sync with the gabi webpage") that added a #define for EM_METAG but did not add relocations This triggers build errors: scripts/recordmcount.c: In function 'do_file': scripts/recordmcount.c:466:28: error: 'R_METAG_ADDR32' undeclared (first use in this function) case EM_METAG: reltype = R_METAG_ADDR32; ^~~~~~~~~~~~~~ scripts/recordmcount.c:466:28: note: each undeclared identifier is reported only once for each function it appears in scripts/recordmcount.c:468:20: error: 'R_METAG_NONE' undeclared (first use in this function) rel_type_nop = R_METAG_NONE; ^~~~~~~~~~~~ Work around this change with some more #ifdefery for the relocations.

of: fix autoloading due to broken modalias with no 'compatible'

2016-07-27T16:47:28+00:00

commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b upstream. Because of an improper dereference, a stray 'C' character was output to the modalias when no 'compatible' was specified. This is the case for some old PowerMac drivers which only set the 'name' property. Fix it to let them match again.

scripts/package/Makefile: rpmbuild add support of RPMOPTS

2016-06-08T01:14:37+00:00

commit 65a9f31c5042e5bb50d30ed8ae374044be561054 upstream. After commit 21a59991ce0c ("scripts/package/Makefile: rpmbuild is needed for rpm targets"), it is no longer possible to specify RPMOPTS. For example, we can no longer able to control _topdir using the following make command. make RPMOPTS="--define '_topdir /home/xyz/workspace/'" binrpm-pkg Fixes: 21a59991ce0c ("scripts/package/Makefile: rpmbuild is needed for rpm targets") Signed-off-by: Srinivas Pandruvada Signed-off-by: Michal Marek Signed-off-by: Greg Kroah-Hartman

kbuild: move -Wunused-const-variable to W=1 warning level

2016-06-01T19:15:54+00:00

commit c9c6837d39311b0cc14cdbe7c18e815ab44aefb1 upstream. gcc-6 started warning by default about variables that are not used anywhere and that are marked 'const', generating many false positives in an allmodconfig build, e.g.: arch/arm/mach-davinci/board-da830-evm.c:282:20: warning: 'da830_evm_emif25_pins' defined but not used [-Wunused-const-variable=] arch/arm/plat-omap/dmtimer.c:958:34: warning: 'omap_timer_match' defined but not used [-Wunused-const-variable=] drivers/bluetooth/hci_bcm.c:625:39: warning: 'acpi_bcm_default_gpios' defined but not used [-Wunused-const-variable=] drivers/char/hw_random/omap-rng.c:92:18: warning: 'reg_map_omap4' defined but not used [-Wunused-const-variable=] drivers/devfreq/exynos/exynos5_bus.c:381:32: warning: 'exynos5_busfreq_int_pm' defined but not used [-Wunused-const-variable=] drivers/dma/mv_xor.c:1139:34: warning: 'mv_xor_dt_ids' defined but not used [-Wunused-const-variable=] This is similar to the existing -Wunused-but-set-variable warning that was added in an earlier release and that we disable by default now and only enable when W=1 is set, so it makes sense to do the same here. Once we have eliminated the majority of the warnings for both, we can put them back into the default list. We probably want this in backport kernels as well, to allow building them with gcc-6 without introducing extra warnings.

unbreak allmodconfig KCONFIG_ALLCONFIG=...

2016-05-04T21:48:54+00:00

commit 6b87b70c5339f30e3c5b32085e69625906513dc2 upstream. Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections?

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.

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.
