pcibios_get_irq_routing_table is an exported symbol. This results in a

On MIPS with PCI && !HOTPLUG, I'm currently getting the following modpost
warning:
MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x1ce128): Section mismatch: reference to .init.text:pci_read_bridge_bases (between 'pcibios_fixup_bus' and 'pcibios_enable_device')
On MIPS I have the call chains pci_scan_child_bus -> pcibios_fixup_bus ->
pci_read_bridge_bases. pci_scan_child_bus can't be __devinit because it
it is an exported symbol, thus pcibios_fixup_bus and pci_read_bridge_bases
can't be either.
For some reason I don't see this issue on x86; I blame compiler differences.

The earlier crash dump fix on x86_64 depended on patches in -mm which
are intended for post-2.6.23. Without those, it broke the build when
it went into 2.6.23-rc5.
This changes the field references in ELF_CORE_COPY_REGS back to those
still used in mainline.

In the case when an nmi gets stucks the endflag stays equal to zero.
This causes the busy looping on other cpus to continue, even though the
nmi test is done.
On my machine with out the change below the system would hang right
after check_nmi_watchdog(). The change below just sets endflag prior to
checking if the test was successful or not.

Fix the NMI watchdog on Intel CoreDuo processor where the kernel would
get stuck during boot. The issue is related to errata AE49, where the
PERFEVTSEL1 counter does not have a working enable bit. Thus it is not
possible to use it for NMI.
The patch creates a dedicated wd_ops for CoreDuo which falls back to
using PERFEVTSEL0. The other Intel processors supporting the
architectural PMU will keep on using PERFEVTSEL1 as this allows other
subsystems, such as perfmon, to use PERFEVTSEL0 for PEBS monitoring in
particular. Bug initially reported by Daniel Walker.

fsid_source decided where to get the 'fsid' number to
return for a GETATTR based on the type of filehandle.
It can be from the device, from the fsid, or from the
UUID.
It is possible for the filehandle to be inconsistent
with the export information, so make sure the export information
actually has the info implied by the value returned by
fsid_source.

*exp_get* now returns -ENOENT rather than NULL and when
commit 5d3dbbeaf56d0365ac6b5c0a0da0bd31cc4781e1
removed the NULL checks, it didn't add a check for -ENOENT.

When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the
TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This
means that when a new tracer comes along and does PTRACE_ATTACH, it's
possible he gets a syscall tracing stop even though he's never used
PTRACE_SYSCALL. This happens if the task was in the middle of a system
call when the second PTRACE_ATTACH was done. The symptom is an
unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have
been provoked by his ptrace calls so far.
A few machines already fixed this in ptrace_disable (i386, ia64, m68k).
But all other machines do not, and still have this bug. On x86_64, this
constitutes a regression in IA32 compatibility support.
Since all machines now use TIF_SYSCALL_TRACE for this, I put the
clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather
than adding it to every other machine's ptrace_disable.

Fix "lost" interrupt problem when using dma with CD/DVD drives in some
configurations. This problem can make installing linux from media
impossible for distro's that have switched to libata-only configurations.
The simple fix is to eliminate the use of dma for reading drive status, etc,
by checking the number of bytes to transferred.
This change will only affect the behavior of atapi devices, not disks.
There is more info at http://bugzilla.redhat.com/show_bug.cgi?id=242229
This patch is for 2.6.22.1

Following a strict interpretation the empty definition of irq_enable_hazard
has always been a bug - but an intentional one because it didn't bite.
This has now changed, for uniprocessor kernels mm/slab.c:do_drain()
[...]
on_each_cpu(do_drain, cachep, 1, 1);
check_irq_on();
[...]
may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting
in a back-to-back hazard.

Previously, ibmebus derived a device's bus_id from its location code.
The location code is not guaranteed to be unique, so we might get bus_id
collisions if two devices share the same location code. The OFDT
full_name, however, is unique, so we use that instead (truncating it
on the left if it is too long).

On PS3, A storage device may show up in the repository before the hypervisor
has finished probing:
- If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY,
- If its regions are being probed, it shows up as having zero regions.
If any of these happen, consider the device not yet present. The storage
probe thread will retry later.
This fixes the timing-dependent problem where a kernel booted from FLASH ROM
sometimes cannot find the hard disk.

At present, running any SPE program on the ps3 will trigger a BUG_ON
when spufs_run_spu tries to clear the master run control bit, as lv1
does not make the master run control available to Linux.
This change makes SPE apps work again by disabling changes to the
master run control on PS3. Although we don't have the facility to
disable a SPE with supervisor-level privileges, it's better than
hitting the BUG_ON unconditionally.

interrupt.
The Cell BE Architecture spec states that the SPU MFC Class 0 interrupt
is edge-triggered. The current spu interrupt handler assumes this
behavior and does not clear the interrupt status.
The PS3 hypervisor visualizes all SPU interrupts as level, and on return
from the interrupt handler the hypervisor will deliver a new virtual
interrupt for any unmasked interrupts which for which the status has not
been cleared. This fix clears the interrupt status in the interrupt
handler.

This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN,
used to implement i2c_smbus_read_block_data(). Previously, in the
absence of PEC (rarely used!) it would NAK the "length" byte:
S addr Rd [A] [length] NA
That prevents the subsequent data bytes from being read:
S addr Rd [A] [length] { A [data] }* NA
The primary fix just reorders two code blocks, so the length used
in the "should I NAK now?" check incorporates the data which it
just read from the slave device.
However, that move also highlighted other fault handling glitches.
This fixes those by abstracting the RX path ack/nak logic, so it
can be used in more than one location. Also, a few CodingStyle
issues were also resolved.
