parisc: add ftrace (function and graph tracer) functionality

2009-03-31T02:51:34Z

This patch adds the ftrace debugging functionality to the parisc kernel. It will currently only work with 64bit kernels, because the gcc options -pg and -ffunction-sections can't be enabled at the same time and -ffunction-sections is still needed to be able to link 32bit kernels.

parisc: allow to build with 16k default kernel page size

2009-03-31T02:51:33Z

Introduce new convert_for_tlb_insert20 macro and use it to replace assembler statements with hardcoded constants. This change allows the parisc64 kernel to boot with 16kb default kernel page size, aka CONFIG_PARISC_PAGE_SIZE_16KB=y. Signed-off-by: Helge Deller Signed-off-by: Kyle McMartin

parisc: use constants instead of numbers in assembly

2009-03-31T02:51:33Z

A few small fixups: * _PAGE_SIZE_ENCODING_DEFAULT is wrong here, as one might assume that it's possible to define the page size that way. This is wrong. Use 0 instead. * use constants instead of hardcoded numerical values in depi and extru while building the PFN out of the pte entry * use SHRREG instead of extru (iitlba expects the PFN at bits {7..26}) Still wondering why we can use the same register (pte) as extru source and target register, but it seems to work on PA1.1 and PA2.0...

parisc: add braces around arguments in assembler macros

2009-03-13T05:18:27Z

Add braces around the macro arguments, else for example "shl %r1, 5-3, %r2" would not expand to what you would assume. Signed-off-by: Helge Deller Signed-off-by: Kyle McMartin

parisc: fix trivial section name warnings

2008-05-15T14:38:54Z

This trivial patch fixes the following section warnings on PARISC: > WARNING: vmlinux.o (.text.1): unexpected section name. >The (.[number]+) following section name are ld generated and not expected. > Did you forget to use "ax"/"aw" in a .S file? > Note that for example contains > section definitions for use in .S files.

[PARISC] Kill off broken irqstack code

It's been unfinished and broken long enough, and I have some ideas on how to do it more cleanly. Signed-off-by: Kyle McMartin

[PARISC] fix "reduce size of task_struct on 64-bit machines" fallout

2007-05-30T06:27:46Z

Amazingly, parisc was the only arch effected by this... Convert register-sized loads/stores to always be 32-bit for these fields. Signed-off-by: Kyle McMartin
