Building with the attached .config on x86-64, it does this:
CC arch/um/kernel/smp.o
In file included from include/asm/arch/tlb.h:11,
from include/asm/tlb.h:4,
from arch/um/kernel/smp.c:8:
include/asm-generic/tlb.h: In function ‘tlb_flush_mmu’:
include/asm-generic/tlb.h:76: error: implicit declaration of function ‘release_pages’
include/asm-generic/tlb.h: In function ‘tlb_remove_page’:
include/asm-generic/tlb.h:105: error: implicit declaration of function ‘page_cache_release’
make[1]: *** [arch/um/kernel/smp.o] Error 1
make: *** [arch/um/kernel] Error 2
I've been doing the following to fix it. I know it's not the right fix,
(see the earlier thread about it at http://lkml.org/lkml/2007/8/24/441 )
but could the one line fix go into the -stable queue 2.6.23 while a proper
fix goes into 2.6.24?

Fix build break in User Mode Linux 2.6.23.1.

I think the patches that I have just added to the stable queue for
2.6.23.2 will fix this. If not, please let me know after testing.

Where do I find these patches to test? I know where to find the stable
releases, but not the "stable queue".
Documentation/stable_kernel_rules.txt just says there _is_ a stable queue, not
where to access it. Google's first hit for "linux stable queue" was
http://git.kernel.org/?p=linux/kernel/git/chrisw/stable-queue.git;a=shortlog
which apparently stopped updating in march...
Happy to test the patch you mentioned, if I can figure out where to find it...
Thanks,
Rob

It's at:
http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=summary
Chris and I used to have separate queues, but that got messy, I suppose
we should just delete those old copies...

In a freshly extracted 2.6.23 tarball, I applied the 4 uml-*.patch files from
stable-queue/review-2.6.23-2 in sequence (all applied cleanly), and then did
the following:
cat > mini.conf << EOF &&
CONFIG_BINFMT_ELF=y
CONFIG_HOSTFS=y
CONFIG_LBD=y
CONFIG_BLK_DEV=y
CONFIG_BLK_DEV_LOOP=y
CONFIG_STDERR_CONSOLE=y
CONFIG_UNIX98_PTYS=y
CONFIG_EXT2_FS=y
EOF
make ARCH=um allnoconfig KCONFIG_ALLCONFIG=mini.conf
Then I did:
make -j 2 ARCH=um
And it still breaks:

Heh, we came full circle here, this was Rob's original patch :)
Rob, I'll queue this up for the next cycle, now that you've verified
that it was not fixed already, thanks for testing.

If you look further down the file, you see a comment to the effect that this
will break sparc.

I wouldn't.
sparc includes swap.h in its pgtable.h. Adding pagemap.h to swap.h
completes an include loop on sparc which blows up its build.
I have a set of patches to fix this in a different way, which I sent
out for comments a few weeks ago. They
add uaccess.h to various futexes.h because these will start
failing to build when the next patch is applied
break the recursion by removing highmem.h from pagemap.h,
which needs nothing related to highmem, and sprinkle includes of
highmem.h in all the files which formerly got it through pagemap.h
now, pagemap.h can be added to swap.h without blowing up sparc
also, the other arches can include swap.h in their pgtables.h,
which they probably should since they define operations on
swp_entry_t, which is defined in swap.h.

/me pleads the fifth.
(I'm all for a better fix in .24, but for .23.x this is a one-liner...)

I wasn't cc'd, and missed it. I'd like to test this, do you have a link? (Or
a bit more specificity than "a few weeks ago"?)

Doesn't contain a patch.

Doesn't apply to vanilla 2.6.23, it can't find two files and a couple other
hunks failed.

Took me one minute to locate PATCH 1 + 2:
http://marc.info/?l=linux-arch&m=119342916429513&w=2

Same problem as previous message: they don't apply to 2.6.23. (I tried both
2.6.23 and 2.6.23.8, just to be sure.)
I don't suppose putting #ifndef guards around whatever sparc.h file hasn't got
them is a reasonable hack to get this worked around during 2.6.23.x?
