The following calltrace is possible now:
handle_sysrq
machine_emergency_restart
mach_reboot_fixups
pci_get_device
pci_get_subsys
down_read
The patch skips reboot fixup if called from sysrq-B code.Signed-off-by: Denis V. Lunev

On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish
call context requirement: unlike its dma_alloc_coherent() sibling, it may
not be called with IRQs disabled. (This was new behavior on ARM as of late
2005, caused by ARM SMP updates.) This little surprise can be annoyingly
driver-visible.Since it looks like that restriction won't be removed, this patch changes
the definition of the API to include that requirement. Also, to help catch
nonportable drivers, it updates the x86 and swiotlb versions to include the
relevant warnings. (I already observed that it trips on the
bus_reset_tasklet of the new firewire_ohci driver.)Signed-off-by: David Brownell

Currently find_legacy_serial_ports() can find no serial ports on the
OPB with flattened device tree. Thus no legacy boot console can be
initialized. Just the early udbg console works, which is initialized
with udbg_init_44x_as1 on the UART's physical address specified in
kernel config. This happens because we look for ns16750 serial
devices only and expect opb node to have a device type property. This
patch makes it look for ns16550-compatible devices and use
of_device_is_compatible() for opb in case device type is not
specified.Signed-off-by: Valentine Barshak
Signed-off-by: Paul Mackerras -
This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments. That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.Parts of this patch were originally written by Ben Herrenschmidt.
