try_then_request_module() does what crypto/autoload.c is doing, so replace it. Fix try_then_request_module(), too (thanks James).

Cleanup ikconfig - use single_open for built_with file. - get rid of unneeded globals - use copy_to_user instead of char at a time - only need the read routine, proc defaults to correct behaviour for the rest.

When mmap MAP_SHARED is done on a file, it gets marked with VM_MAYSHARE and, if it's read/write, VM_SHARED. However, if it is remapped with mremap(), the MAP_SHARED is only passed into the new mapping based on VM_SHARED. This means that remapped read only MAP_SHARED mappings lose VM_MAYSHARE. This is causing us a problem on parisc because we have to align all shared mappings carefully to mitigate cache aliasing problems. The fix is to key passing the MAP_SHARED flag back into the remapped are off VM_MAYSHARE not VM_SHARED.

driver->supports_dma was used together with CONFIG_IDEDMA_ONLYDISK to limit DMA access to disk devices only. However Alan introduced new scheme in 2.5.63 and this field is not needed any longer because all ide drivers support DMA.

Some references to irq_stat[] snuck into generic code. It doesn't work on several architectures. So revert that little improvement to the original version.

It seems that changing CONFIG_BLK_DEV_INITRD causes the whole kernel to rebuild due to an inappropriate ifdef in linux/fs.h - we should not conditionalise prototypes. In addition, real_root_dev is only used by two files (kernel/sysctl.c and init/do_mounts_initrd.c) so it makes even less sense that it was in linux/fs.h

This patch fixes a logic bug in NAT range calculations, which also causes a large slowdown when ICMP floods go through NAT. Author: Karlis Peisenieks

From: Rusty Russell <rusty@rustcorp.com.au> Rather than hardcoded names in modprobe, modules can offer their own aliases (which can be overridden by the config file). Here are the tty-ldisc ones.

From: Rusty Russell <rusty@rustcorp.com.au> Please delete Documentation/kmod.txt: it's entirely outdated and misleading. I thought about rewriting it, but there's not much to add beyond what's in the CONFIG_KMOD's help text.

The same address `i8042_request_irq_cookie' is used in three places for the i8042 request_irq() argument. This means that if someone calls i8042_check_mux() or i8042_check_aux() while the IRQ is in use, the free_irq() call in there will free the wrong IRQ handler. So give all three instances of request_irq() in i8042.c a distinct address by which to identify the IRQ instance. (This is probably a non-bug, because the `check' functions are not called when the device is open, but it is better this way).

From: James Morris <jmorris@redhat.com> This patch adds an 'selinux' boot parameter which must be used to actually enable SELinux. It follows some internal discussion about deployment issues, where a vendor would want to ship a single kernel image with SELinux built-in, without requiring the user to use it. Without specifying selinux=1 as a boot parameter, SELinux will not register with LSM and selinuxfs will not be registered as a filesystem. This causes SELinux to be bypassed entirely from then on, and no performance overhead is imposed. Other security modules may then also be loaded if needed.

From: Ravikiran G Thirumalai <kiran@in.ibm.com> The routine disk_round_stats showed up considerably under oprofile for high disk io load (four processes doing dd to the same disk (different partitions) on a 4 way). This is because the counter in_flight which is per-cpu right now gets read every time disk_round_stats gets called. Per cpu counters like disk statistics improve write speed, but reads are slow (since all cpus' local counter values have to be read and summed up). Considering the fact that in_flight counter is modified post disk_round_stats (which reads the in_flight counter) it is better not to per-cpu this counter. Following patch does just that. Below is the profile comparison before and after the change. This was on a 4 way PIII Xeon, 1G ram, 2.6.0-test4-mm2.

From: Mitchell Blank Jr <mitch@sfgoth.com> This patch makes the following improvements to might_sleep(): o Add a "might_sleep_if()" macro for when we might sleep only if some condition is met. It's a bit tidier, and has an unlikely() in it. o Add might_sleep checks to skb_share_check() and skb_unshare() which sometimes need to allocate memory. o Make all architectures call might_sleep() in both down() and down_interruptible(). Before only ppc, ppc64, and i386 did this check. (sh did the check on down() but not down_interruptible())
