parisc64: don't use module_init for non-modular core perf code

2015-06-16T18:12:30+00:00

The perf.c code depends on CONFIG_64BIT, so it is either built-in
or absent.  It will never be modular, so using module_init as an
alias for __initcall is rather misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.  Aside from it not making sense, it also
causes a ~10% increase in CPP overhead due to module.h having a
large list of headers itself -- for example compare line counts:

 device_initcall() and 
	20238 arch/parisc/kernel/perf.i

 module_init() and 
	22194 arch/parisc/kernel/perf.i

Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero.   Should someone with real hardware
for boot testing want to change it later to arch_initcall or
something different, they can do that at a later date.

parisc: remove big kernel lock

2010-10-16T20:43:08+00:00

The parisc version of the perf code is sufficiently
protected by its own spinlock, no need to use the BKL.

tree-wide: fix a very frequent spelling mistake

2009-11-09T08:40:54+00:00

something-bility is spelled as something-blity
so a grep for 'blit' would find these lines

this is so trivial that I didn't split it by subsystem / copy
additional maintainers - all changes are to comments
The only purpose is to get fewer false positives when grepping
around the kernel sources.

[PATCH] mark struct file_operations const 2

2007-02-12T17:48:44+00:00

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

Remove the lock_kernel/unlock_kernel pair in the ioctl method. It
