ARC: SMP failed to boot due to missing IVT setup

2013-09-12T14:40:08Z

Commit 05b016ecf5e7a "ARC: Setup Vector Table Base in early boot" moved the Interrupt vector Table setup out of arc_init_IRQ() which is called for all CPUs, to entry point of boot cpu only, breaking booting of others. Fix by adding the same to entry point of non-boot CPUs too. read_arc_build_cfg_regs() printing IVT Base Register didn't help the casue since it prints a synthetic value if zero which is totally bogus, so fix that to print the exact Register.

It prevents kernel parameters such as 'loglevel' from doing their job. Signed-off-by: Mischa Jonker Signed-off-by: Vineet Gupta

arc: delete __cpuinit usage from all arc files

2013-06-27T09:07:58Z

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/arc uses of the __cpuinit macros from all C files. Currently arc does not have any __CPUINIT used in assembly files.

ARC: [cmdline] Don't overwrite u-boot provided bootargs

2013-05-07T08:13:57Z

The existing code was wrong on several counts: * uboot provided bootargs were copied into @boot_command_line, only to be over-written by setup_machine_fdt(), effectively lost * @cmdline_p returned by setup_arch() to start_kernel() didn't include the DT /bootargs Signed-off-by: Vineet Gupta
