    hexagon: delete __cpuinit usage from all hexagon files · 7ddc8399
    Paul Gortmaker authored
    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 5e427ec2 ("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/hexagon uses of the __cpuinit macros from
    all C files.  Currently hexagon does not have any __CPUINIT used in
    assembly files.
