kdb: fix crash when KDB_BASE_CMD_MAX is exceeded

2010-11-17T19:54:57Z

When the number of dyanmic kdb commands exceeds KDB_BASE_CMD_MAX, the kernel will fault. Signed-off-by: Jovi Zhang Signed-off-by: Jason Wessel

kdb: Fix early debugging crash regression

2010-10-29T18:14:41Z

The kdb_current legally be equal to NULL in the early boot of the x86 arch. The problem pcan be observed by booting with the kernel arguments: earlyprintk=vga ekgdboc=kbd kgdbwait The kdb shell will oops on entry and recursively fault because it cannot get past the final stage of shell initialization.

kdb: fix per_cpu command to remove supress mask

2010-10-29T18:14:40Z

Rusty pointed out that the per_cpu command uses up lots of space on the stack and the cpu supress mask is probably not needed. This patch removes the need for the supress mask as well as fixing up the following problems with the kdb per_cpu command: * The per_cpu command should allow an address as an argument * When you have more data than can be displayed on one screen allow the user to break out of the print loop.

kdb,debug_core: adjust master cpu switch logic against new debug_core locking

2010-10-22T20:34:13Z

The kdb shell needs to enforce switching back to the original CPU that took the exception before restoring normal kernel execution. Resuming from a different CPU than what took the original exception will cause problems with spin locks that are freed from the a different processor than had taken the lock. The special logic in dbg_cpu_switch() can go away entirely with because the state of what cpus want to be masters or slaves will remain unchanged between entry and exit of the debug_core exception context.

kdb: Fix oops in kdb_unregister

2010-10-22T20:34:12Z

Nothing should try to use kdb_commands directly as sometimes it is null. Instead, use the for_each_kdbcmd() iterator. This particular problem dates back to the initial kdb merge (2.6.35), but at that point nothing was dynamically unregistering commands from the kdb shell. Signed-off-by: Jason Wessel

kdb: Allow kernel loadable modules to add kdb shell functions

2010-10-22T20:34:11Z

In order to allow kernel modules to dynamically add a command to the kdb shell the kdb_register, kdb_register_repeat, kdb_unregister, and kdb_printf need to be exported as GPL symbols. Any kernel module that adds a dynamic kdb shell function should only need to include linux/kdb.h. Signed-off-by: Jason Wessel

Input: sysrq - drop tty argument form handle_sysrq()

2010-08-21T07:34:45Z

Sysrq operations do not accept tty argument anymore so no need to pass it to us.
