[IA64] Move include/asm-ia64 to arch/ia64/include/asm

2008-08-01T17:21:21+00:00

After moving the the include files there were a few clean-ups:

1) Some files used #include , changed to 

2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.

3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

[IA64] pvops: preparation: introduce ia64_get_psr_i() to make kernel paravirtualization friendly.

2008-05-27T21:39:07+00:00

__local_irq_save() and local_save_flags() are used to mask interruptions.
They read all psr bits that requres whole bit emulation.
On the other hand, reading only psr.i, the single bit, can be virtualized
cheaply.

[IA64] pvops: preparation: move the constants, LOAD_OFFSET, to a header file.

2008-05-27T21:38:18+00:00

Move the LOAD_OFFSET definition from vmlinux.lds.S into system.h.
On paravirtualized environments, it is necessary to detect the
execution environment. One of the solutions is the multi entry point.
The multi entry point allows a boot loader to start the kernel execution
from the entry point which is different from the ELF entry point.
The non standard entry point will defined as the specialized elf note
which contains the LMA of the entry point symbol.
The constant, LOAD_OFFSET, is necessary to calculate the symbol's LMA.
Move the definition into the public header file to make it available
to the multi entry point support.

fix ia64 local_irq_save() et.al.

2008-04-28T17:03:31+00:00

psr is not a good name for local variable in macro body when it
has a good chance of being the argument of said macro (actually
is at least in one place)

[IA64] VIRT_CPU_ACCOUNTING (accurate cpu time accounting)

2008-02-20T20:55:37+00:00

This patch implements VIRT_CPU_ACCOUNTING for ia64,
which enable us to use more accurate cpu time accounting.

The VIRT_CPU_ACCOUNTING is an item of kernel config, which s390
and powerpc arch have.  By turning this config on, these archs
change the mechanism of cpu time accounting from tick-sampling
based one to state-transition based one.

The state-transition based accounting is done by checking time
(cycle counter in processor) at every state-transition point,
such as entrance/exit of kernel, interrupt, softirq etc.
The difference between point to point is the actual time consumed
during in the state. There is no doubt about that this value is
more accurate than that of tick-sampling based accounting.

increase AT_VECTOR_SIZE to terminate saved_auxv properly

2007-10-17T15:43:00+00:00

include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO.  fs/binfmt_elf.c
has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT
entries.  So in the worst case, saved_auxv does not get an AT_NULL entry at
the end.

The saved_auxv array must be terminated with an AT_NULL entry.  Make the
size of mm_struct->saved_auxv arch dependend, based on the number of
ARCH_DLINFO entries.

[IA64] sparse cleanups

2006-08-02T23:03:44+00:00

Fix some sparse warnings on ia64.  Large constants that should be long
instead of int.  Use NULL instead of 0.  Add some missing __iomem
casts.  Replace a non-C99 structure assignment.

[PATCH] remove set_wmb - arch removal

2006-07-15T04:56:14+00:00

set_wmb should not be used in the kernel because it just confuses the
code more and has no benefit.  Since it is not currently used in the
kernel this patch removes it so that new code does not include it.

All archs define set_wmb(var, value) to do { var = value; wmb(); }
while(0) except ia64 and sparc which use a mb() instead.  But this is
still moot since it is not used anyway.

Hasn't been tested on any archs but x86 and x86_64 (and only compiled
tested)
