- s/freeliest/freelist/ spelling fix - Check for NULL *z zone seems useless - even if it could happen, so what? Perhaps we should have a check later on if we are faced with an allocation request that is not allowed to fail - shouldn't that be a serious kernel error, passing an empty zonelist with a mandate to not fail? - Initializing 'z' to zonelist->zones can wait until after the first get_page_from_freelist() fails; we only use 'z' in the wakeup_kswapd() loop, so let's initialize 'z' there, in a 'for' loop. Seems clearer. - Remove superfluous braces around a break - Fix a couple errant spaces - Adjust indentation on the cpuset_zone_allowed() check, to match the lines just before it -- seems easier to read in this case. - Add another set of braces to the zone_watermark_ok logic From: Paul Jackson <pj@sgi.com> Backout one item from a previous "memory page_alloc minor cleanups" patch. Until and unless we are certain that no one can ever pass an empty zonelist to __alloc_pages(), this check for an empty zonelist (or some BUG equivalent) is essential. The code in get_page_from_freelist() blow ups if passed an empty zonelist.

OpenVZ Linux kernel team has found a problem with mounting in compat mode. Simple command "mount -t smbfs ..." on Fedora Core 5 distro in 32-bit mode leads to oops: Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: compat_sys_mount+0xd6/0x290 Process mount (pid: 14656, veid=300, threadinfo ffff810034d30000, task ffff810034c86bc0) Call Trace: ia32_sysret+0x0/0xa The problem is that data_page pointer can be NULL, so we should skip data conversion in this case.

Here's a patch that cleans up the "make help" output a bit for the documentation targets. Currently the documentation targets are listed completely different than all the other targets : Documentation targets: Linux kernel internal documentation in different formats: xmldocs (XML DocBook), psdocs (Postscript), pdfdocs (PDF) htmldocs (HTML), mandocs (man pages, use installmandocs to install) with this patch they are more in line with the rest of the output : Documentation targets: Linux kernel internal documentation in different formats: htmldocs - HTML installmandocs - install man pages generated by mandocs mandocs - man pages pdfdocs - PDF psdocs - Postscript xmldocs - XML DocBook Signed-off-by: NJesper Juhl <jesper.juhl@gmail.com> Acked-by: NRandy Dunlap <randy.dunlap@oracle.com> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Any code that relies on the volatile would be a bug waiting to happen anyway. Don't encourage people to think that putting 'volatile' on data structures somehow fixes problems.

__do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

I was playing with blackfin when i hit a neat bug ... doing an open() on a directory and then passing that fd to mmap() would cause the kernel to hang after poking into the code a bit more, i found that mm/nommu.c:validate_mmap_request() checks the length and if it is 0, just returns the address ... this is in stark contrast to mmu's mm/mmap.c:do_mmap_pgoff() where it returns -EINVAL for 0 length requests ... i then noticed that some other parts of the logic is out of date between the two funcs, so perhaps that's the easy fix ?

The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.
