N32 SysV IPC system calls should use 32-bit compatible code. arch/mips/kernel/linux32.c have similar compatible code for O32, but ipc/compat.c seems more complete. We can use it for both N32 and O32. This patch should fix these problems (and other possible problems): http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1149188824.6986.6.camel%40diimka-laptop http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=44C6B829.8050508%40caviumnetworks.comSigned-off-by:

Switch to pci_get_bus_and_slot because some x86 systems seem to be handing us a device with dev->bus = NULL. Also don't apply the isa fixup to revision C6 and later of the chip. Really we need to work out wtf is handing us pdev->bus = NULL, but firstly and more importantly we need the drivers working. Signed-off-by:

In io_subchannel_register(), it is better to just reprobe the current device if it hasn't a driver yet than to rescan the whole bus. Signed-off-by:

If I/O was running on a just varied off chpid, it will be terminated. If this was a common I/O layer internal I/O, it needs to be retried. Signed-off-by:
-
Cornelia Huck authored
If the last path to a device is gone after a chpid has been varied off, putting it on the slow queue doesn't prevent a device driver from still attempting to use it (it may stay on the slow queue for a long time). Instead, trigger a verify event which will prevent I/O attempts from the device driver immediately. Signed-off-by:

Add some prefixes to constands defined in drivers/s390/net/qdio.h and drivers/s390/lcs.h to make it possible to include the three header files drivers/s390/net/qeth.h, drivers/s390/net/qdio.h and drivers/net/s390/lcs.h in one C file.

VMALLOC_END on 31bit should be 0x8000000UL instead of 0x7fffffffL. The page mask which is used to make sure memory_end is on 4MB/2MB boundary is wrong and not needed. Therefore remove it. Make sure a vmalloc area does also exist and work on (future) machines with 4TB and more memory. Signed-off-by:

Use a wrapper for copy_to/from_user to chose the best usercopy method. The mvcos instruction is better for sizes greater than 256 bytes, if mvcos is not available a page table walk is better for sizes greater than 1024 bytes.

Avoid the tprot loop if diag260 works and reports that there are no holes in memory. The tprot instruction can lead to a significant delay in the ipl process if the virtual guest has a lot of memory and the host is under memory pressure. Signed-off-by:

If the memory detection code would ever reach the point where it would load the wait psw, it would generate a specification exception and the system would crash at ipl time. This is because of a misaligned wait psw. It needs to be on a double word boundary instead of a word boundary. Signed-off-by:

Let one master cpu kill all other cpus instead of sending an external interrupt to all other cpus so they can kill themselves. Simplifies reipl/shutdown functions a lot. Signed-off-by:
-
Heiko Carstens authored
In case of reipl cpcmd gets called when all other cpus are not running anymore. To prevent deadlocks change __cpcmd so that it doesn't take any locks and call cpcmd or __cpcmd, whatever is correct in the current context. Signed-off-by:

KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one. Otherwise the kexec control page can be allocated above 2GB which will cause a specification exception on the sam31 instruction in the s390 kexec relocation code. Signed-off-by:
