From: Cornelia Huck <cohuck@de.ibm.com> From: Thomas Spatzier <tspat@de.ibm.com> common i/o layer changes: - Prevent double unregister of ccw devices. - Move unregister out of the subchannel remove function, to avoid live-lock due to hotplug if the root device is currently indisposed. - Delete pending timer after a machine check. - Revert change to allocate qdio queues and SLIBS in DMA memory. - Decrement ccw_device_init_count only after ccw_device_register is done. - Remove unnecessary check in ccw_hotplug.

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> This one covers the fact, that the SIGSEGV signal, which is created by force_sigsegv() in case of an error in handle_signal(), is not delivered to the user immediately. In the worst case it even could be masked if a sigprocmask() systemcall follows immediately after return from kernel. The patch is relevant for other architectures, too. Signed-off-by:

Jeff Dike authored
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> If the user stack limit is reached or the signal stack assigned with sigaltstack() is invalid when a user signal handler with SA_ONSTACK has to be started, the signal mask of the interrupted user program is modified. This happens because the mask, that should be used with the handler only, is written to "current->blocked" even if the handler could not be started. But without a handler, no rewrite of the original mask at sys_sigreturn will be done. A slightly different case is sys_sigsuspend(), where the mask is already modified when kern_do_signal() is started. "*oldset" and "current->blocked" are not equal here and thus current->blocked has to be set to *oldset, if an error occurs in handle_signal(). For both cases I've written small tests, and with the patch the result is OK. This issue is relevant for other architectures too (e.g. i386, I've seen). Signed-off-by:

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> This makes the UML signal frame construction interface somewhat more similar to x86 than before. Also, some small code cleanup, and checking for errors before changing the signal mask in the SA_NODEFER case. Signed-off-by:

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> Change the interface to handle_signal so that it doesn't take the system call return value as an argument and eliminate its return value. kern_do_signal also now doesn't return immediately after determining that there is no signal to deliver.

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> Change the do_signal interface to eliminate its argument. Also, remove the calls from the system call handlers since they are redundant. In all cases, pending signals are checked for in the interrupt handler. Temporarily, do_signal passes the current error to kern_do_signal. Signed-off-by:

Jeff Dike authored
This patch fixes a bug introduced in the last batch of signal fixes. The system call return value should only be reset if called diectly from a system call, i.e. sigsuspend. The fixes added earlier caused any interrupted non-zero system call return to be reset, confusing fork and vfork, among others. Signed-off-by:

This patchset was originally from NIIBE Yutaka. These patch update the m32r kernel for a new bootloader "m32r-g00ff". The "m32r-g00ff" has been written and developed by NIIBE Yutaka, and released under the GPL from http://www.gniibe.org/. So far, it supports two types of booting operations, CF boot and Network boot (HTTP boot). * CF boot - boot from CompactFlash or Microdrive(TM) We can boot a kernel from CF device. To make use of m32r-g00ff, we just put a first stage IPL(initial program loader) into a flash memory, and a secondary bootloader into CF media device. Currently, LILO-21.4.4 can be used to write m32r-g00ff into the boot sector of CF device on a cross development environment. * HTTP boot - boot via network with HTTP protocol By using m32r-g00ff, we can download and boot a kernel image from a web-server. The m32r-g00ff downloads a kernel image from a given URL, resolving the webserver's IP address by DNS. As a preparation, we just place a secondary bootloader binary and a kernel image on the webserver. - Position-independent zImage support; this aims at removing constraints of zImage(vmlinuz)'s location.

Both detect_init_APIC() and init_apic_mappings() it's called from are invoked early, before the command line has been processed. Therefore its meaningless to call apic_printk() from them as that depends on apic_verbosity which is initialized from the command line. I could move apic_verbosity initialization to parse_cmdline_early(), but I think that would be an overkill, the point being we are initerested in feedback from detect_init_APIC() anyway. Without that it's hard to tell what's really going on as it's been the case with the recent report of the local APIC being non-functional despite the whole setup being apparently correct. So I converted these calls to ordinary printk() invocations. The init_apic_mappings() are less interesting, so I've made them output at the debug level. While at it I've made some obvious nearby formatting clean-up. Signed-off-by:

The patch adds cpu_relax() in the body of some spin loops for 2.6.9. The patch also removes redundant barrier() code after cpu_relax() on ia32. In the PAUSE instruction section, IA32 SDM claims "it is recommended that a PASUE instruction be placed in all spin-wait loops". And x86_64 SDM says that PAUSE instruction is same as legacy mode in IA-32e mode operation. This patch is against 2.6.9 (kernel.org). It was tested on ia32 and x86_64. Acked-by:

This patch is from Jake Moilanen <moilanen@austin.ibm.com>. There appears to be a hole that if we get an log_error() call, that we could zero out our error log count in nvram. When rtasd() starts up, it turns on the logging via 'no_more_logging = 0'. If we get a log_error() call after that is set but before nvram_read_error_log has actually read nvram to set error_log_cnt, the log_error() call will write back to nvram a uninitialized error_log_cnt value, and wipe out our sequence number. To close the hole, simply move the 'no_more_logging = 0' till after nvram sets error_log_cnt but before pSeries_log_error is called. I also changed the 'no_more_logging' variable to be 'no_logging' since it's not only used when we stop logging now. I also removed the "volatile" part of no_more_logging, since it's unneeded.

We duplicated the code in pci_alloc_pci_controller twice and had an ifdef for iseries as well, just to select between kmalloc and bootmem memory. Change this so we instead pass the allocation into a common function - pci_setup_pci_controller. Also use a spinlock around the host_list and global_phb_number code since we now can modify it at runtime via hotplug. Signed-off-by:
