FRV: Drop the .data.idt section for FRV

2008-02-21T03:58:16+00:00

There is no .data.idt section for FRV, so drop it from the linker script.

xtime_lock vs update_process_times

2008-02-13T21:29:25+00:00

Commit d3d74453c34f8fd87674a8cf5b8a327c68f22e99 ("hrtimer: fixup the
HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since
only Russell bothered to merge the fix, and Greg to ACK his arch, I'm
sending this for merger.

I have confirmation that the Alpha bit results in a booting kernel.
That leaves: blackfin, frv, sh and sparc untested.

The deadlock in question was found by Russell:

  IRQ handle
    -> timer_tick() - xtime seqlock held for write
      -> update_process_times()
        -> run_local_timers()
          -> hrtimer_run_queues()
            -> hrtimer_get_softirq_time() - tries to get a read lock

Now, Thomas assures me the fix is trivial, only do_timer() needs to be
done under the xtime_lock, and update_process_times() can savely be
removed from under it.

FRV: Fix up parse error in linker script

2008-02-13T16:26:01+00:00

Fix up parse error in FRV linker script, presumably introduced through changes
to the INIT_TEXT and EXIT_TEXT macros.

Introduce flags for reserve_bootmem()

2008-02-07T16:42:25+00:00

This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.

This patch:

Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past.  This is to avoid conflicts.

Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().

calibrate_delay() must be __cpuinit

2008-02-06T18:41:08+00:00

calibrate_delay() must be __cpuinit, not __{dev,}init.

I've verified that this is correct for all users.

While doing the latter, I also did the following cleanups:
- remove pointless additional prototypes in C files
- ensure all users #include 

This fixes the following section mismatches with CONFIG_HOTPLUG=n,
CONFIG_HOTPLUG_CPU=y:

WARNING: vmlinux.o(.text+0x1128d): Section mismatch: reference to .init.text.1:calibrate_delay (between 'check_cx686_slop' and 'set_cx86_reorder')
WARNING: vmlinux.o(.text+0x25102): Section mismatch: reference to .init.text.1:calibrate_delay (between 'smp_callin' and 'cpu_coregroup_map')

FRV: permit the memory to be located elsewhere in NOMMU mode

2008-02-05T17:44:20+00:00

Permit the memory to be located somewhere other than address 0xC0000000 in
NOMMU mode.  The configuration options are already present, it just
requires wiring up in the linker script.

Note that only a limited set of locations of runtime addresses are available
because of the way the CPU protection registers work.

move frv docs one level up

2008-02-03T13:54:28+00:00

My first guess for "fujitsu" was it might be related to the
fujitsu-laptop.c driver...

Move the frv directory one level up since frv is the name of the
architecture in the Linux kernel.
