* [PATCH] uml: add _text definition to linker scriptsJeff Dike2006-10-31
| | | | | | | | | | kallsyms now refers to addresses as '_text + 0xADDRESS', rather than just '0xADDRESS', so we need to define _text.

* [PATCH] uml ubd driver: various little changesPaolo 'Blaisorblade' Giarrusso2006-10-31
| | | | | | | | | | | | | | | | | | Fix a small memory leak in ubd_config, and clearify the confusion which lead to it. Then, some little changes not affecting operations - * move init functions together, * add a comment about a potential problem in case of some evolution in the block layer, * mark all initcalls as static __init functions * mark an used once little function as inline * document that mconsole methods are all called in process context (was triggered when checking ubd mconsole methods).

* [PATCH] uml ubd driver: convert do_ubd to a boolean variablePaolo 'Blaisorblade' Giarrusso2006-10-31
| | | | | | | | | | | | do_ubd is actually just a boolean variable - the way it is used currently is a leftover from the old 2.4 block layer, but it is still used; its use is suspicious, but removing it would be too intrusive for now and needs more thinking.

* [PATCH] uml ubd driver: ubd_io_lock usage fixupPaolo 'Blaisorblade' Giarrusso2006-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | Add some comments about requirements for ubd_io_lock and expand its use. When an irq signals that the "controller" (i.e. another thread on the host, which does the actual requests and is the only one blocked on I/O on the host) has done some work, we call again the request function ourselves (do_ubd_request). We now do that with ubd_io_lock held - that's useful to protect against concurrent calls to elv_next_request and so on. XXX: Maybe we shouldn't call at all the request function. Input needed on this. Are we supposed to plug and unplug the queue? That code "indirectly" does that by setting a flag, called do_ubd, which makes the request function return (it's a residual of 2.4 block layer interface). Meanwhile, however, merge this patch, which improves things.

* [PATCH] uml ubd driver: change ubd_lock to be a mutexPaolo 'Blaisorblade' Giarrusso2006-10-31
| | | | | | | | | | | | | | This lock protects ubd setup and teardown, so is only used in process context; beyond that, during such setup memory allocations must be performed and some generic functions which can sleep must be called (such as add_disk()). So the only correct solution is to make it a mutex instead of a spin_lock. No other change is done - this lock must be acquired in different places but it's done afterwards.

* [PATCH] uml ubd driver: give better names to some functions.Paolo 'Blaisorblade' Giarrusso2006-10-31
| | | | | | | | | | | | | | | To rethink locking, I needed to understand well what each function does. While doing this I renamed some: * ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev) * ubd_new_disk -> ubd_disk_register (it handles registration with the block layer - one hopes this makes clearer the difference with ubd_add()) Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Cc: Jeff Dike <jdike@addtoit.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | Rename the ubd_dev array to ubd_devs and then call any "struct ubd" ubd_dev instead of dev, which doesn't make clear what we're treating (and no, it's not hungarian notation - not any more than calling all vm_area_struct vma or all inodes inode).

For instance, without this patch userspace objects are never compiled with debug info active.

* [PATCH] Fix "Remove the use of _syscallX macros in UML"Paolo 'Blaisorblade' Giarrusso2006-10-30
| | | | | | | | | | | | | | | | | | Fix commit 5f4c6bc1f369f20807a8e753c2308d1629478c61: it spits out warnings about missing syscall prototype (it is in <unistd.h>) and it does not recognize that two uses of _syscallX are to be resolved against kernel headers in the source tree, not against _syscallX; they in fact do not compile and would not work anyway. If _syscallX macros will be removed from the kernel tree altogether, the only reasonable solution for that piece of code is switching to open-coded inline assembly (it's remapping the whole executable from memory, except the page containing this code).
