parisc: move dereference_function_descriptor to process.c

2009-04-02T04:16:27+00:00

Commit deac93df26b20cf8438339b5935b5f5643bc30c9 fixed up printing
of %pF on parisc, but added the dereference_function_descriptor
prototype to module.c... this isn't a particularly wise idea as
module.c might not always be compiled.

parisc: Move kernel Elf_Fdesc define to

2009-04-02T04:16:24+00:00

elf.h probably won't be exported to userspace, but play it safe
and cram it in a #ifdef __KERNEL__ guard.

parisc: fix module loading failure of large kernel modules

2009-01-04T22:10:14+00:00

On 32bit (and sometimes 64bit) and with big kernel modules like xfs or
ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
fail to reach their PLT stub if we only create one big stub array for
all sections at the beginning of the core or init section.

With this patch we now instead add individual PLT stub entries
directly in front of the code sections where the stubs are actually
called. This reduces the distance between the PCREL location and the
stub entry so that the relocations can be fulfilled.

While calculating the final layout of the kernel module in memory, the
kernel module loader calls arch_mod_section_prepend() to request the
to be reserved amount of memory in front of each individual section.

Tested with 32- and 64bit kernels.

lib: Correct printk %pF to work on all architectures

2008-09-09T18:51:15+00:00

It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer
formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2.  However,
the current way its coded doesn't work on parisc64.  For two reasons: 1)
parisc isn't in the #ifdef and 2) parisc has a different format for
function descriptors

Make dereference_function_descriptor() more accommodating by allowing
architecture overrides.  I put the three overrides (for parisc64, ppc64
and ia64) in arch/kernel/module.c because that's where the kernel
internal linker which knows how to deal with function descriptors sits.

[PATCH] Fix conflict with the is_init identifier on parisc

2006-09-29T16:18:12+00:00

This appears to be the only usage of is_init in the kernel besides the
usage in sched.h.  On ia64 the same function is called in_init.  So to
remove the conflict and make the kernel more consistent rename is_init
is_core is_local and is_local_section to in_init in_core in_local and
in_local_section respectively.

Thanks to Adrian Bunk who spotted this, and to Matthew Wilcox
who suggested this fix.

[PARISC] Fix PCREL22F relocation problem for most modules

2006-06-27T23:28:44+00:00

The new problem, which has been affecting many more modules was that
our new ioremap really takes chunks out of our vmalloc space.  The net
result being that any two kernel vmalloc's now have to slot into the
chunked up space.  So the vmallocs for a modules init and core sectons
are no longer necessarily contiguous.  Unfortunately, the module loader
thinks that any internal symbol references should be satisfiable using the
jump instruction, which isn't true if the symbol is referenced from init
to core and vmalloc placed them a long way apart.

Fix this by introducing a new stub type for intra module inter sectional
jumps and using it.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
