- Removed some kmalloc's with __GFP_ZERO and replace it with memset() because it didn't work properly. - Fixed returned message frame in i2o_cfg_passthru() which caused raidutils to display wrong error message in case a disk was missing. - Fixed size of printk() in i2o_scsi.c. - Fixed get_device() and put_device() in probing of the I2O controller.

Changed the I2O API to create I2O messages first in kernel memory and then transfer it at once over the PCI bus instead of sending each quad-word over the PCI bus. Signed-off-by:

Sanitize some s390 Kconfig options. We have ARCH_S390, ARCH_S390X, ARCH_S390_31, 64BIT, S390_SUPPORT and COMPAT. Replace these 6 options by S390, 64BIT and COMPAT. Signed-off-by:

When the sclp_cpi module is loaded on a system which does not support the required SCLP call (e.g. on z/VM), ENOSUPP is returned to user space. The correct return value is EOPNOTSUPP. Signed-off-by:

Add support for multiple subchannel sets. Works with arbitrary devices in subchannel set 1 and is transparent to device drivers. Although currently only two subchannel sets are available, this will work with the architectured maximum number of subchannel sets as well. Signed-off-by:

for_each_subchannel() is an iterator calling a function for every possible subchannel id until non-zero is returned. Convert the current iterating functions to it. Signed-off-by:
-
Cornelia Huck authored
This patch introduces a struct subchannel_id containing the subchannel number (formerly referred to as "irq") and switches code formerly relying on the subchannel number over to it. While we're touching inline assemblies anyway, make sure they have correct memory constraints. Signed-off-by:

New feature V=V qdio pass-through. QDIO and HiperSockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements. Especially the shadowing of SBALs and SLSBs structures in the hypervisor, and the need to issue SIGA SYNC operations to observe state changes, eventually causes significant CPU processing overhead in the hypervisor. The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O. Signed-off-by:

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:

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:
