2010-08-21Input: sysrq - drop tty argument form handle_sysrq()Dmitry Torokhov
Sysrq operations do not accept tty argument anymore so no need to pass it to us. [Stephen Rothwell <sfr@canb.auug.org.au>: fix build breakage in drm code caused by sysrq using bool but not including linux/types.h] [Sachin Sant <sachinp@in.ibm.com>: fix build breakage in s390 keyboadr driver] Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Acked-by: Jason Wessel <jason.wessel@windriver.com> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-08-05kgdb,kdb: individual register set and and get APIJason Wessel
The kdb shell specification includes the ability to get and set architecture specific registers by name. For the time being individual register get and set will be implemented on a per architecture basis. If an architecture defines DBG_MAX_REG_NUM > 0 then kdb and the gdbstub will use the capability for individually getting and setting architecture specific registers.

The xtime cleanup missed the kgdb access to xtime. Fix it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2010-07-22sysrq,kdb: Use __handle_sysrq() for kdb's sysrq functionJason Wessel
The kdb code should not toggle the sysrq state in case an end user wants to try and resume the normal kernel execution. Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2010-07-22Fix merge regression from external kdb to upstream kdbJason Wessel
In the process of merging kdb to the mainline, the kdb lsmod command stopped printing the base load address of kernel modules. This is needed for using kdb in conjunction with external tools such as gdb. Simply restore the functionality by adding a kdb_printf for the base load address of the kernel modules.

2010-05-21printk,kdb: capture printk() when in kdb shellJason Wessel
Certain calls from the kdb shell will call out to printk(), and any of these calls should get vectored back to the kdb_printf() so that the kdb pager and processing can be used, as well as to properly channel I/O to the polled I/O devices.

2010-05-21kdb: core for kgdb back end (1 of 2)Jason Wessel
This patch contains only the kdb core. Because the change set was large, it was split. The next patch in the series includes the instrumentation into the core kernel which are mainly helper functions for kdb. This work is directly derived from kdb v4.4 found at: ftp://oss.sgi.com/projects/kdb/download/v4.4/ The kdb internals have been re-organized to make them mostly platform independent and to connect everything to the debug core which is used by gdbstub (which has long been known as kgdb). The original version of kdb was 58,000 lines worth of changes to support x86. From that implementation only the kdb shell, and basic commands for memory access, runcontrol, lsmod, and dmesg where carried forward. This is a generic implementation which aims to cover all the current architectures using the kgdb core: ppc, arm, x86, mips, sparc, sh and blackfin. More archictectures can be added by implementing the architecture specific kgdb functions.
