lock_memory() and unlock_memory() will now silently fail and return success -
that's only to get things working.

Also made elf_lookup_symbol_address() less restrictive with respect to the
ELF symbol found (it now accepts all types, not only functions).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7714 a95241bf-73f2-0310-859d-f6bbb57e9c96
tested, though.
No longer copies the elf_header in insert_preloaded_image(); it's not used
at runtime (should be superfluous to keep in other kernel images, too).
dump_symbols() now ignores entries with invalid values - don't know exactly
what makes a good entry, but that should look okay.

standard byte order functions in the kernel).
Small cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7705 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed warnings when compiled with TRACE_ELF.
Changed elf_lookup_symbol_address() to returning more useful information.
It now also scans the extended debug symbol table if present - for now, this
only works with preloaded images except the kernel.

(in BeOS, all kernel areas are r/w).
If you use B_READ_AREA/B_WRITE_AREA flags, you make the area readable
or even writeable from userland!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now uses the extended possibilities of the elf_lookup_symbol_address() call.
Fixed a bug in dbg_stack_trace(); it could crash at the top most stack frame.

to deny further port/sem allocation (and also simplifies port/sem stats).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7570 a95241bf-73f2-0310-859d-f6bbb57e9c96
like any other module (yeeha!).
You can even unload preloaded images later on (to replace them with a
more up-to-date on disk version).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7532 a95241bf-73f2-0310-859d-f6bbb57e9c96
If an image cannot be created out of a preloaded_image, its resources
are freed now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7531 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Fixed missign file system unload.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7527 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now registers its images as it should do (so you can use commands like
listimage in userland).
Added new debugger command "image".

to acquire the team spinlock).
Renamed the user syscalls to the new style.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7521 a95241bf-73f2-0310-859d-f6bbb57e9c96
freed in the wrong order in case of an error (could have crashed the kernel).
Implemented insert_preloaded_images() which prepares the preloaded images
for later use in the kernel.
