I saw that 2.6.10 has been released under hardened-dev so I emerged, hoping to get reiser4 patched. Suprisingly, reiser4 patched fine (unlike bootsplash) and after doing the menuconfig, at the VERY END of make I get:

Now, I realize that I patched an already heavily-patched kernel, but I'm still hoping that this will eventually work. I'm not sure if it's a patch problem or a kernel problem (I haven't compiled the kernel w/o reiser4), but has anybody else had this problem? Or better yet, anybody have any idea how to fix it...?

Ok, after looking at the kernel source and errors (thanks Linsam) we made the following changes (the kernel COMPILES, i'm not sure if it'll actually NOT crash  )
in /usr/src/linux/mm/mmap.c:
line 2262: ret =do_brk(addr, len);
should be ret = __do_brk(addr, len);
line 2268: EXPORT_SYMBOL(do_brk);
should be in between an ifdef statement
#ifdef CONFIG_PAX_PAGEEXEC
EXPORT_SYMBOL(do_brk);
#endif
NOTE: this will prolly break thinks on a non-x86 platform since a previous def was made for them !
in /usr/src/linux/fs/binfmt_elf.c:
line 101: retval = do_brk(start, end - start);
should prolly be retval = do_brk_locked(start, end - start);
Like I previously said, I have no kernel experience so this shall all be tested as soon as I reboot under the new kernel. I STRONGLY suggest some developer takes a look at this and writes a patch.
Since this is not a reiser4-patch problem (most likely) it's prolly a general 2.6.10-hardened-dev-sources issue.

ok, that doesn't fix the problem but hangs the system at INIT or "freeing unused kernel memory".
Suggestions?
