Replace all references to z990 by s390 in the in-kernel crypto files in arch/s390/crypto. The code is not specific to a particular machine (z990) but to the s390 platform. Big diff, does nothing.. Signed-off-by:

To properly support multipath-failover handling, the linux block layer has introduced a special request flag, 'REQ_FAILFAST'. This flag is now used to return requests immediately in case the device is not operational. Signed-off-by:

The IOCTL BIODASDPRRD had no return code for 'profiling is inactive' and therefore tunedasd wrote misleading message for request-counter = 0. Introduce return-code EIO for inactive profiling. Signed-off-by:

If we receive path not operational indications (pnom in pmcw nonzero), we switch off those paths. To catch them becoming available again, we have to recalculate the lpm from the pmcw each time we start path verification. Signed-off-by:

There are some more places where the use of cputime_t instead of an integer type and the associated macros is necessary for the virtual cputime accounting on s390. Affected are the s390 specific appldata code and BSD process accounting. Signed-off-by:

Hugh Dickins <hugh@veritas.com> Fix the broken atomic_cmpxchg primitive. Add atomic_sub_and_test, atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg, atomic64_add_unless and atomic64_inc_not_zero. Replace old style atomic_compare_and_swap by atomic_cmpxchg. Shorten the whole header by defining most primitives with the two inline functions atomic_add_return and atomic_sub_return. In addition this patch contains the s390 related fixes of Hugh's "mm: fill arch atomic64 gaps" patch. Signed-off-by:Hugh Dickins <hugh@veritas.com> Signed-off-by:

Free the network IRQ when closing down the network devices at shutdown. Delete the device from the opened devices list on close. These prevent an -EBADF when later disabling SIGIO on all extant descriptors and a complaint from free_irq about freeing the IRQ twice. Signed-off-by:

Pass sysrq output back to the mconsole client using the mechanism introduced for stack output. Signed-off-by:
-
Jeff Dike authored
The stack command now sends the printk output back to the mconsole client. This is done by registering a special console for the mconsole driver. This receives all printk output. Normally, it is ignored, but when a stack command is issued, any printk output will be sent back to the client. This will capture any printk output, whether it is stack output or not, since we can't tell the difference. Signed-off-by:

This is needed for the console output patch, since we have a possibly non-NULL-terminated string there. So, the new interface takes a string and a length, and the old interface calls strlen on its string and calls the new interface with the length. There's also a bit of whitespace cleanup.

This patch cleans up the umid code: - The only_if_set argument to get_umid is gone. - get_umid returns an empty string rather than NULL if there is no umid. - umid_is_random is gone since its users went away. - Some printfs were turned into printks because the code runs late enough that printk is working. - Error paths were cleaned up. - Some functions now return an error and let the caller print the error message rather than printing it themselves. This eliminates the practice of passing a pointer to printf or printk in, depending on where in the boot process we are. - Major tidying of not_dead_yet - mostly error path cleanup, plus a comment explaining why it doesn't react to errors the way you might expect. - Calls to os_* interfaces that were moved under os are changed back to their native libc forms. - snprintf, strlcpy, and their bounds-checking friends are used more often, replacing by-hand bounds checking in some places.

I reworked Gennady's umid OS abstraction patch because the code shouldn't be moved entirely to os. As it turns out, I moved most of it anyway. This patch is the minimal one needed to move the code and have it work. It turns out that the concept of the umid is OS-independent, but almost everything else about the implementation is OS-dependent. This is code movement without cleanup - a follow-on patch tidies everything up without shuffling code around. Signed-off-by:

Jeff Dike authored
When the tty flip_buf is full, it's a good idea to delay the input processing for a jiffy, rather than just scheduling the tasklet immediately. Signed-off-by:

This patch simplifies the opening and closing of host console devices and the registration and deregistration of IRQs. The intent is to make it obvious that an IRQ can't exist without an open file descriptor. chan_enable will now open the channel, and when both opening and IRQ registration are desired, this should be used. Opening only is done for the initial console, so that interface still needs to exist. The free_irqs_later interface is now gone. It was intended to avoid freeing an IRQ while it was being processed. It did this, but it didn't eliminate the possiblity of free_irq being called from an interrupt, which is bad. In its place is a list of irqs to be freed, which is processed by the signal handler just before exiting. close_one_chan now disables irqs. When a host device disappears, it is just closed, and that disables IRQs. The device id registered with the IRQ is now the chan structure, not the tty. This is because the interrupt arrives on a descriptor associated with the channel. This caused equivalent changes in the arguments to line_timer_cb. line_disable is gone since it is not used any more. The count field in the line structure is gone. tty->count is used instead. The complicated logic in sigio_handler with freeing IRQs when necessary and making sure its idea of the next irq is correct is now much simpler. The irq list can't be rearranged underneath it, so it is now a simple list walk. Signed-off-by:

This patch changes when console devices are configured in order to prepare the ground for the next patch. parse_chan_pair is now done earlier, when initcalls are run, rather than when the device is opened. When a host device disappears, the channel list is closed, but not freed. This is required by the previous change. line_config now takes the options structure as an argument, and line_open doesn't.

Some structure fields were being dynamically initialized when they could be initialized at compile-time instead. This also makes some declarations static (in the C sense). Signed-off-by:

This patch makes a bunch of non-functional changes - return(foo); becomes return foo; some statements are broken across lines for readability some trailing whitespace is cleaned up open_one_chan took four arguments, three of which could be deduced from the first. Accordingly, they were eliminated. some examples of "} else {" had a newline added some whitespace cleanup in the indentation lines_init got some control flow cleanup some long lines were broken removed another emacs-specific C formatting comment Signed-off-by: -

There are a few functions which are declared to return something, but don't. These are actually infinite loops which are forced to be declared as non-void. This makes them all return 0. Signed-off-by:

There were a bunch of calls to uml_strdup dating from before kstrdup was introduced. This changes those calls. It doesn't eliminate the definition since there is still a couple of calls in userspace code (which should probably call the libc strdup). Signed-off-by:

This patch is for updating m32r's MMU-less support. Some legacy MMU-less m32r chips cannot return from a trap handler to the right-hand side 16-bit halfword code of a 32-bit instrucion code pair, because a "trap" instruction specification was expanded in M32R-II ISA. This modification forces "trap" instructions to be placed in word alignment location with a parallel "nop" code. Signed-off-by:
