* Report that kernel is tainted if there was an OOPSPavel Emelianov2007-07-17
| | | | | | | | | | | | | | If the kernel OOPSed or BUGed then it probably should be considered as tainted. Thus, all subsequent OOPSes and SysRq dumps will report the tainted kernel. This saves a lot of time explaining oddities in the calltraces.

* [ARM] 4453/1: Fully Decode ARM instruction set state in show_regs() tombstoneGeorge G. Davis2007-07-12
| | | | | | | | | | | | The ARM show_regs() tombstone only partially decodes which ARM ISA was executing at the time a fault occurred displaying either "(T)" for the Thumb case or nothing at all for other cases. This patch therefore explicitly identifies which state the processor is in at the time of a fault: ARM, Thumb, Jazelle or JazelleEE. Signed-off-by: George G.

* [ARM] always allow dump_stack() to produce a backtraceRussell King2007-07-05

* Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARMDavid Woodhouse2007-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | Not all the world is an i386. Many architectures need 64-bit arguments to be aligned in suitable pairs of registers, and the original sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an argument register for padding after the first integer. Since we don't normally have more than 6 arguments for system calls, that left no room for the final argument on some architectures. Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which all fits nicely. In fact, ARM already had that, but called it sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement the needed compatibility routine. And stop the missing syscall check from bitching about the absence of sys_sync_file_range() if we've implemented sys_sync_file_range2() instead. Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

* [ARM] Update show_regs/oops register formatRussell King2007-06-18
| | | | | | | | | | | | Add the kernel release and version information to the output of show_regs/oops. Add the CPU PSR register. Avoid using printk to output partial lines; always output a complete line. Re-combine the "Control" and "Table + DAC" lines after nommu separated them; we don't want to waste vertical screen space needlessly. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] Fix stacktrace FP range checkingRussell King2007-05-30
| | | | | | | | | Fix an oops in the stacktrace code, caused by improper range checking. We subtract 12 off 'fp' before testing to see if it's below the low bound.

* | move die notifier handling to common codeChristoph Hellwig2007-05-08
|/ | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.
