2013-05-01dump_stack: unify debug information printed by show_regs()Tejun Heo1-1/+1
show_regs() is inherently arch-dependent but it does make sense to print generic debug information and some archs already do albeit in slightly different forms. This patch introduces a generic function to print debug information from show_regs() so that different archs print out the same information and it's much easier to modify what's printed. show_regs_print_info() prints out the same debug info as dump_stack() does plus task and thread_info pointers. * Archs which didn't print debug info now do. alpha, arc, blackfin, c6x, cris, frv, h8300, hexagon, ia64, m32r, metag, microblaze, mn10300, openrisc, parisc, score, sh64, sparc, um, xtensa * Already prints debug info. Replaced with show_regs_print_info(). The printed information is superset of what used to be there. arm, arm64, avr32, mips, powerpc, sh32, tile, unicore32, x86 * s390 is special in that it used to print arch-specific information along with generic debug info. Heiko and Martin think that the arch-specific extra isn't worth keeping s390 specfic implementation. Converted to use the generic version. Note that now all archs print the debug info before actual register dumps.

2013-05-01dump_stack: consolidate dump_stack() implementations and unify their behaviorsTejun Heo1-13/+0
Both dump_stack() and show_stack() are currently implemented by each architecture. show_stack(NULL, NULL) dumps the backtrace for the current task as does dump_stack(). On some archs, dump_stack() prints extra information - pid, utsname and so on - in addition to the backtrace while the two are identical on other archs. The usages in arch-independent code of the two functions indicate show_stack(NULL, NULL) should print out bare backtrace while dump_stack() is used for debugging purposes when something went wrong, so it does make sense to print additional information on the task which triggered dump_stack(). There's no reason to require archs to implement two separate but mostly identical functions. It leads to unnecessary subtle information. This patch expands the dummy fallback dump_stack() implementation in lib/dump_stack.c such that it prints out debug information (taken from x86) and invokes show_stack(NULL, NULL) and drops arch-specific dump_stack() implementations in all archs except blackfin. Blackfin's dump_stack() does something wonky that I don't understand. Debug information can be printed separately by calling dump_stack_print_info() so that arch-specific dump_stack() implementation can still emit the same debug information. This is used in blackfin. This patch brings the following behavior changes. * On some archs, an extra level in backtrace for show_stack() could be printed. This is because the top frame was determined in dump_stack() on those archs while generic dump_stack() can't do that reliably. It can be compensated by inlining dump_stack() but not sure whether that'd be necessary. * Most archs didn't use to print debug info on dump_stack(). They do now. An example WARN dump follows. WARNING: at kernel/workqueue.c:4841 init_workqueues+0x35/0x505() Hardware name: empty Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.9.0-rc1-work+ #9 0000000000000009 ffff88007c861e08 ffffffff81c614dc ffff88007c861e48 ffffffff8108f50f ffffffff82228240 0000000000000040 ffffffff8234a03c 0000000000000000 0000000000000000 0000000000000000 ffff88007c861e58 Call Trace: [<ffffffff81c614dc>] dump_stack+0x19/0x1b [<ffffffff8108f50f>] warn_slowpath_common+0x7f/0xc0 [<ffffffff8108f56a>] warn_slowpath_null+0x1a/0x20 [<ffffffff8234a071>] init_workqueues+0x35/0x505 ... v2: CPU number added to the generic debug info as requested by s390 folks and dropped the s390 specific dump_stack(). This loses %ksp from the debug message which the maintainers think isn't important enough to keep the s390-specific dump_stack() implementation. dump_stack_print_info() is moved to kernel/printk.c from lib/dump_stack.c. Because linkage is per objecct file, dump_stack_print_info() living in the same lib file as generic dump_stack() means that archs which implement custom dump_stack() - at this point, only blackfin - can't use dump_stack_print_info() as that will bring in the generic version of dump_stack() too. v1 The v1 patch broke build on blackfin due to this issue.

2013-04-30mm/hugetlb: add more arch-defined huge_pte functionsGerald Schaefer1-0/+1
Commit abf09bed3cce ("s390/mm: implement software dirty bits") introduced another difference in the pte layout vs. the pmd layout on s390, thoroughly breaking the s390 support for hugetlbfs. This requires replacing some more pte_xxx functions in mm/hugetlbfs.c with a huge_pte_xxx version. This patch introduces those huge_pte_xxx functions and their generic implementation in asm-generic/hugetlb.h, which will now be included on all architectures supporting hugetlbfs apart from s390. This change will be a no-op for those architectures.

Seems the new PAGE_MASK is explicitly 32bit, or one could make it signed instead of unsigned long.

The of_node field of the device assigned to a PCI bus is used during scanning of the PCI bus. However on MIPS, the of_node field is assigned only after the bus has been scanned. Implement the architecture specific version of 'pcibios_get_phb_of_node'. Which ensures that the PCI driver core will initialize the of_node field before starting the scan. Also remove the local assignment of bus->dev.of_node, it is not needed after the patch. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever supported its use and no libc was using it, so the entire sa-restorer functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.] for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid accidental reuse of the mask bit. Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear sa_restorer on execve] adds code that assumes sa_sigaction has an sa_restorer field, if SA_RESTORER is defined which would break MIPS.

2013-04-01net: add option to enable error queue packets waking selectKeller, Jacob E1-0/+2
Currently, when a socket receives something on the error queue it only wakes up the socket on select if it is in the "read" list, that is the socket has something to read. It is useful also to wake the socket if it is in the error list, which would enable software to wait on error queue packets without waking up for regular data on the socket. The main use case is for receiving timestamped transmit packets which return the timestamp to the socket via the error queue. This enables an application to select on the socket for the error queue only instead of for the regular traffic. -v2- * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file * Modified every socket poll function that checks error queue Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Cc: Jeffrey Kirsher <jeffrey.t.kirsher@intel.com> Cc: Richard Cochran <richardcochran@gmail.com> Cc: Matthew Vick <matthew.vick@intel.com> Signed-off-by: David S.

pnx833x does not seem to use the generic gpio API. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
2013-03-20arm: remove redundant GENERIC_GPIO selectionAlexandre Courbot1-2/+0
GENERIC_GPIO was selected next to ARCH_REQUIRE_GPIOLIB, which itself selects GENERIC_GPIO. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
2013-03-20mips: alchemy: require gpiolibAlexandre Courbot1-2/+1
Require gpiolib instead of just GENERIC_GPIO. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
2013-03-20mips: txx9: change GENERIC_GPIO to GPIOLIBAlexandre Courbot1-1/+1
The GPIO driver for txx9 requires gpiolib, so this is more accurate and let us get rid of one mention of GENERIC_GPIO which is due to disappear. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
2013-03-20mips: loongson: use GPIO driver on CONFIG_GPIOLIBAlexandre Courbot1-1/+1
The GPIO driver uses gpiolib, thus it should be compiled when CONFIG_GPIOLIB is defined and not only CONFIG_GENERIC_GPIO. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
