Remove the last vestiges of devfs from console registration. Change the name of the function, plus remove a couple of unused fields from the line_driver structure. struct lines is no longer needed, all traces of it are gone. The only way that I can see to mark a structure as being almost-const is to individually const the fields. This is the case for the line_driver structure, which has only one modifiable field - a list_head in a sub-structure. Signed-off-by:

The chan_opts structure is mostly const, and needs no locking. Comment the lack of locking on the one field that can change. Make all the other fields const. It turned out that console_open_chan didn't use its chan_opts argument, so that is deleted from the function and its callers. Signed-off-by:

Locking fixes. Locking was totally lacking for the mconsole_devices, which got a spin lock, and the unplugged pages data, which got a mutex. The locking of the mconsole console output code was confused. Now, the console_lock (renamed to client_lock) protects the clients list. Signed-off-by:

The registration of host network transports needed some locking. The transport list itself is locked, but calls to the registration routines are not. This is compensated for by checking that a transport structure is not yet on any list. I also took the opportunity to const all fields in the transport structure except the list, which obviously can be modified. Signed-off-by:

Some comment and whitespace cleanups in the console and mconsole code. Signed-off-by:
-
Jeff Dike authored
I noticed that errors happening while hotplugging devices from the host were never returned back to the mconsole client. In some cases, success was returned instead of even an information-free error. This patch cleans that up by having the low-level configuration code pass back an error string along with an error code. At the top level, which knows whether it is early boot time or responding to an mconsole request, the string is printk'd or returned to the mconsole client. There are also whitespace and trivial code cleanups in the surrounding code. Signed-off-by:

Clean up the console driver locking. There are various problems here, including sleeping under a spinlock and spinlock recursion, some of which are fixed here. This patch deals with the locking involved with opens and closes. The problem is that an mconsole request to change a console's configuration can race with an open. Changing a configuration should only be done when a console isn't opened. Also, an open must be looking at a stable configuration. In addition, a get configuration request must observe the same locking since it must also see a stable configuration. With the old locking, it was possible for this to hang indefinitely in some cases because open would block for a long time waiting for a connection from the host while holding the lock needed by the mconsole request. As explained in the long comment, this is fixed by adding a spinlock for the use count and configuration and a mutex for the actual open and close. Signed-off-by:

kernel/time/clocksource.c needs struct task_struct on m68k. Because it uses spin_unlock_irq(), which, on m68k, uses hardirq_count(), which uses preempt_count(), which needs to dereference struct task_struct, we have to include sched.h. Because it would cause a loop inclusion, we cannot include sched.h in any other of asm-m68k/system.h, linux/thread_info.h, linux/hardirq.h, which leaves this ugly include in a C file as the only simple solution.

Recent as(1) doesn't think that . terminates a macro name, so getuser.l is _not_ treated as invoking getuser with .l as the first argument. arch/m68k/math-emu relies on old behaviour, so it gets a lot of undefined macros with more or less current binutils. Note that this behaviour remains in all recent versions and is unrelated to another binutils problems we used to have for a while (having (%a0)+ parsed as two arguments). This one is there to stay; it's an intentional and documented change. .irp <identifier> <words> [text] .endr expands to a copy of text per each word, with \<identifier> replaced with corresponding word. Again, what happens depends on whether gas_ident.x is treated as one or as two tokens; in the former case we'll get old_gas incremented once, in the latter - twice. The rest is obvious. Unlike .macro argument list _anything_ is explicitly allowed after .irp <identifier>; here we are on very safe ground. And yes, it does work with all gas variants I've got here (including vanilla 2.15, 2.16, 2.16.1 and 2.17, plus debian and FC binutils). Signed-off-by:
