2012-08-24powerpc/kgdb: Restore current_thread_info properlyTiejun Chen1-2/+9
For powerpc BooKE and e200, singlestep is handled on the critical/dbg exception stack. This causes current_thread_info() to fail for kgdb internal, so previously We work around this issue by copying the thread_info from the kernel stack before calling kgdb_handle_exception, and copying it back afterwards. But actually we don't do this properly. We should backup current_thread_info then restore that when exit.

2012-08-24powerpc/kgdb: Do not set kgdb_single_step on ppcTiejun Chen1-1/+0
The kgdb_single_step flag has the possibility to indefinitely hang the system on an SMP system. The x86 arch have the same problem, and that problem was fixed by commit 8097551d9ab9b9e3630(kgdb,x86: do not set kgdb_single_step on x86). This patch does the same behaviors as x86's patch.

The current layout is to place the per-process tables at the end of the GTT.

2012-08-24can: sja1000_platform: fix wrong flag IRQF_SHARED for interrupt sharingSven Schmitt1-1/+3
The sja1000 platform driver wrongly assumes that a shared IRQ is indicated with the IRQF_SHARED flag in irq resource flags. This patch changes the driver to handle the correct flag IORESOURCE_IRQ_SHAREABLE instead. There are no mainline users of the platform driver which wrongly make use of IRQF_SHARED.
