Robin Holt f5f7eac41d Allow rwlocks to re-enable interrupts
Pass the original flags to rwlock arch-code, so that it can re-enable
interrupts if implemented for that architecture.

Initially, make __raw_read_lock_flags and __raw_write_lock_flags stubs
which just do the same thing as non-flags variants.

Helge Deller d75f054a2c parisc: add ftrace (function and graph tracer) functionality
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.

Colin Watson 445c088f88 parisc: expose 32/64-bit capabilities in cpuinfo
It'd be rather useful for debian-installer if we could get hold of
accurate firmware information on whether only 32-bit kernels are
supported, only 64-bit kernels, or both; this would allow us to present
an accurate menu of kernel packages if more than one is available,
rather than the user having to guess. This patch attempts to expose it
in cpuinfo.

I adjusted pdc_model_capabilities to cope with a potential
PDC_INVALID_ARG return as the firmware manual instructs, by assuming
32-bit only. This may be the wrong place for it.

I made up user-visible capability names by total fiat and for the moment
ignored the other bits that may appear in the capabilities word.

I have no PA-RISC machine myself to test on, and no PA experience
either, so I rather hope that somebody will kind-heartedly take this and
fix it up if needed. I ran it past Dann Frazier on IRC and he said
"looks good to me", but I think without testing.

Also, this is against the Ubuntu 2.6.28 kernel tree since that's what I
had handy and I was a bit tight on disk space to slurp down another
tree. Sorry if it's skewed in any relevant way; I'll be happy to adjust
if necessary.

Thanks in advance!

Helge Deller 48d27cb229 parisc: fix usage of 32bit PTE page table entries on 32bit kernels
This patch fixes a long outstanding bug on 32bit parisc linux kernels
which prevented us from using 32bit PTE table entries (instead of 64bit
entries of which 32bit were unused).

The problem was caused by this assembler statement in the L2_ptep
macro in arch/parisc/kernel/entry.S:447:
	EXTR \va,31-ASM_PGDIR_SHIFT,ASM_BITS_PER_PGD,\index
which expanded to
	extrw,u r8,9,11,r1
and which has undefined behavior since the length value (11) extends
beyond the leftmost bit (11-1 > 9).
Interestingly PA2.0 processors seem to don't care and just zero-extend
the value, while PA1.1 processors don't.

Fix this problem by detecting an address space overflow with ASM_BITS_PER_PGD
and adjusting it accordingly. To prevent such problems in the future,
some compile time sanity checks in arch/parisc/mm/init.c were added.

Since the page table now only consumes half of it's old size, we can
use the freed memory to harmonize 32- and 64bit kernels and let both
map 16MB for the initial page table.

Patrick Ohly cb9eff0978 net: new user space API for time stamping of incoming and outgoing packets
User space can request hardware and/or software time stamping.
Reporting of the result(s) via a new control message is enabled
separately for each field in the message because some of the
fields may require additional computation and thus cause overhead.
User space can tell the different kinds of time stamps apart
and choose what suits its needs.

When a TX timestamp operation is requested, the TX skb will be cloned
and the clone will be time stamped (in hardware or software) and added
to the socket error queue of the skb, if the skb has a socket
associated with it.

The actual TX timestamp will reach userspace as a RX timestamp on the
cloned packet. If timestamping is requested and no timestamping is
done in the device driver (potentially this may use hardware
timestamping), it will be done in software after the device's
start_hard_xmit routine.

Honestly, I can't decide whether to apply this. It really should never
happen in the kernel, since the kernel can guarantee it won't get the
access rights failure (highest privilege level, and can set %sr and
%protid to whatever it wants.)

It really genuinely is a bug that probably should panic the kernel. The
only precedent I can easily see is x86 fixing up a bad iret with a
general protection fault, which is more or less analogous to code 27
here.

On the other hand, taking the exception on a userspace access really
isn't all that critical, and there's fundamentally little reason for the
kernel not to SIGSEGV the process, and continue...

Argh.

(btw, I've instrumented my do_sys_poll with a pile of assertions that
 %cr8 << 1 == %sr3 == current->mm.context... let's see if where we're
 getting corrupted is deterministic, though, I would guess that it won't
 be.)

Helge Deller c298be7449 parisc: fix module loading failure of large kernel modules
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.

Kay Sievers 90f671301a parisc: struct device - replace bus_id with dev_name(), dev_set_name()
(I did not compile or test it, please let me know, or help fixing
 it, if something is wrong with the conversion)

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

Thanks,
Kay

Geert Uytterhoeven 9860d1b08b parisc: __kernel_time_t is always long
__kernel_time_t is always long on PA-RISC, irrespective of CONFIG_64BIT,
hence move it out of the #ifdef CONFIG_64BIT / #else / #endif block.

Helge Deller 81e192d6ce parisc: convert to generic compat_sys_ptrace
This patch does the compat_sys_ptrace conversion for parisc.
In addition it does convert the parisc ptrace code to use the
architecture-independent ptrace infrastructure instead of own coding.

James Bottomley f0514ae323 parisc: initialize unwinder much earlier
The unwinder was being initialized way too late to be any use
debugging early boot crashes. Instead of relying on module_init
initcalls to initialize it, let's do it explicitly as early as
we can.

Kyle McMartin 24b574d052 parisc: add pdc_coproc_cfg_unlocked and set_firmware_width_unlocked
These functions are called only when bringing up the monarch cpu,
so it is safe to call them without taking the pdc spinlock. In the
future, this may become relevant for lockdep, since these functions were
taking spinlocks before start_kernel called the lockdep initializers.
