* sparc: cleanup references to deprecated .text.init* sections.Tim Abbott2009-04-272-2/+2
| | | | | | | | | | | | | | The section .text.init.refok is deprecated and __REF (.ref.text) should be used in assembly files instead. This patch cleans up a few uses of .text.init.refok in the sparc architecture. Also fix a reference to .text.init in a comment that wasn't updated to .init.text.

* sparc: convert to use __HEAD and HEAD_TEXT macros.Tim Abbott2009-04-262-2/+2
| | | | | | | | | | | This has the consequence of changing the section name use for head code from ".text.head" to ".head.text". Since this commit changes all users in the architecture, this change should be harmless. Signed-off-by: Tim Abbott <tabbott@mit.edu> Cc: David S.

| * sparc: Fix bus type probing for ESP and LE devices.David S. Miller2009-04-222-4/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there is a dummy "espdma" or "ledma" parent device above ESP scsi or LE ethernet device nodes, we have to match the bus as SBUS. Otherwise the address and size cell counts are wrong and we don't calculate the final physical device resource values correctly at all. Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling of LANCE and ESP parent nodes in of_device.c") was meant to fix this problem, but that only influences the inner loop of build_device_resources(). We need this logic to also kick in at the beginning of build_device_resources() as well, when we make the first attempt to determine the device's immediate parent bus type for 'reg' property element extraction. Based almost entirely upon a patch by Friedrich Oslage. Tested-by: Meelis Roos <mroos@linux.ee> Signed-off-by: David S. Miller <davem@davemloft.net>

One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real struct cpumask *), and remove CPU_MASK_ALL_PTR altogether. Also remove the confusing and deprecated large-NR_CPUS-only "cpu_mask_all".

So use a reboot notifier to shut off the NMI watchdog. Signed-off-by: David S. Miller <davem@davemloft.net>

Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
