kcmp: make it depend on CHECKPOINT_RESTORE

2013-02-28T03:10:24Z

Since kcmp syscall has been implemented (initially on x86 architecture) a number of other archs wire it up as well: xtensa, sparc, sh, s390, mips, microblaze, m68k (not taking into account those who uses for syscall numbers definitions). But the Makefile, which turns kcmp.o generation on still depends on former config-x86. Thus get rid of this limitation and make kcmp.o depend on CHECKPOINT_RESTORE option.

Pull kbuild changes from Michal Marek: - Alias generation in modpost is cross-compile safe. - kernel/timeconst.h is now generated using a bc script instead of perl. - scripts/link-vmlinux.sh now works with an alternative $KCONFIG_CONFIG. - destination-y for exported headers is supported in Kbuild files again. - depmod is called with -P $CONFIG_SYMBOL_PREFIX on architectures that need it. - CONFIG_DEBUG_INFO_REDUCED disables var-tracking - scripts/setlocalversion works with too much translated locales ;) * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Fix reading of .config in link-vmlinux.sh kbuild: Unset language specific variables in setlocalversion script Kbuild: Disable var tracking with CONFIG_DEBUG_INFO_REDUCED depmod: pass -P $CONFIG_SYMBOL_PREFIX kbuild: Fix destination-y for installed headers scripts/link-vmlinux.sh: source variables from KCONFIG_CONFIG kernel: Replace timeconst.pl with a bc script mod/file2alias: make modalias generation safe for cross compiling

kernel: Replace timeconst.pl with a bc script

2013-02-16T22:17:25Z

bc is the standard tool for multi-precision arithmetic. We switched to Perl because akpm reported a hard-to-reproduce build hang, which was very odd because affected and unaffected machines were all running the same version of GNU bc. Unfortunately switching to Perl required a really ugly "canning" mechanism to support Perl < 5.8 installations lacking the Math::BigInt module. It was recently pointed out to me that some very old versions of GNU make had problems with pipes in subshells, which was indeed the construct used in the Makefile rules in that version of the patch; Perl didn't need it so switching to Perl fixed the problem for unrelated reasons. With the problem (hopefully) root-caused, we can switch back to bc and do the arbitrary-precision arithmetic naturally. Signed-off-by: H.

MODSIGN: Avoid using .incbin in C source

2012-12-14T02:36:44Z

Using the asm .incbin statement in C sources breaks any gcc wrapper which assumes that preprocessed C source is self-contained. Use a separate .S file to include the siging key and certificate. [ This means we no longer need SYMBOL_PREFIX which is defined in kernel.h from cbdbf2abb7844548a7d7a6a2ae7af6b6fbcea401, so I removed it -- RR ] Tested-by: Michal Marek Signed-off-by: Takashi Iwai Signed-off-by: Rusty Russell Acked-by: James Hogan

Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

2012-12-03T05:27:05Z

Conflicts: arch/x86/kernel/ptrace.c Pull the latest RCU tree from Paul E. McKenney: " The major features of this series are: 1. A first version of no-callbacks CPUs. This version prohibits offlining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU=y. Relaxing this constraint is in progress, but not yet ready for prime time. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/724, and are at branch rcu/nocb. 2. Changes to SRCU that allows statically initialized srcu_struct structures. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/296, and are at branch rcu/srcu. 3. Restructuring of RCU's debugfs output. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/341, and are at branch rcu/tracing. 4. Additional CPU-hotplug/RCU improvements, posted to LKML at https://lkml.org/lkml/2012/10/30/327, and are at branch rcu/hotplug. Note that the commit eliminating __stop_machine() was judged to be too-high of risk, so is deferred to 3.9. 5. Changes to RCU's idle interface, most notably a new module parameter that redirects normal grace-period operations to their expedited equivalents. These were posted to LKML at https://lkml.org/lkml/2012/10/30/739, and are at branch rcu/idle. 6. Additional diagnostics for RCU's CPU stall warning facility, posted to LKML at https://lkml.org/lkml/2012/10/30/315, and are at branch rcu/stall. The most notable change reduces the default RCU CPU stall-warning time from 60 seconds to 21 seconds, so that it once again happens sooner than the softlockup timeout. 7. Documentation updates, which were posted to LKML at https://lkml.org/lkml/2012/10/30/280, and are at branch rcu/doc. A couple of late-breaking changes were posted at https://lkml.org/lkml/2012/11/16/634 and https://lkml.org/lkml/2012/11/16/547. 8. Miscellaneous fixes, which were posted to LKML at https://lkml.org/lkml/2012/10/30/309, along with a late-breaking change posted at Fri, 16 Nov 2012 11:26:25 -0800 with message-ID <20121116192625.GA447@linux.vnet.ibm.com>, but which lkml.org seems to have missed. These are at branch rcu/fixes. 9. Finally, a fix for an lockdep-RCU splat was posted to LKML at https://lkml.org/lkml/2012/11/7/486. This is at rcu/next. " Signed-off-by: Ingo Molnar
