* remove mentionings of devfs in documentationAdrian Bunk2006-10-03
| | | | | | | | | Now that devfs is removed, there's no longer any need to document how to do this or that with devfs. This patch includes some improvements by Joe Perches. Signed-off-by: Adrian Bunk <bunk@stusta.de>
* [PATCH] rename the provided execve functions to kernel_execveArnd Bergmann2006-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures provide an execve function that does not set errno, but instead returns the result code directly. Rename these to kernel_execve to get the right semantics there. Moreover, there is no reasone for any of these architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so remove these right away.

* [PATCH] const struct tty_operationsJeff Dike2006-10-02
| | | | | | | | | | | | | | | | | | | | | | | As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.

* [OPENPROMIO]: Handle current_node being NULL correctly.David S. Miller2006-09-18
| | | | | | | | | | | | If the user tries to traverse to the next node of the last node, we get NULL in current_node and a zero phandle returned. That's fine, but if the user tries to obtain properties in that state, we try to dereference a NULL pointer in the downcall to the of_*() routines. So protect against that. Signed-off-by: David S.

* [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHMChristoph Lameter2006-06-25
| | | | | | | | | | | | | | | | | Remove VM_LOCKED before remap_pfn range from device drivers and get rid of VM_SHM. remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways. Remove all the vm_flags settings before calling remap_pfn_range. After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

* [SPARC]: Kill __irq_itoa().David S. Miller2006-06-20
| | | | | | | | | | | | | | | | | | This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>

We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code. The patch below does that, adding a big comment about what's going on and removing the COMPAT_IOCTL entires for these on powerpc that not only weren't ever useful but are duplicated now aswell.
