* kgdboc: Add call backs to allow kernel mode switchingJason Wessel2010-08-05

* vt,console,kdb: automatically set kdb LINES variableJason Wessel2010-08-05
| | | | | | | | | | | | | The kernel console interface stores the number of lines it is configured to use. The kdb debugger can greatly benefit by knowing how many lines there are on the console for the pager functionality without having the end user compile in the setting or have to repeatedly change it at run time.

* debug_core,kdb: fix crash when arch does not have single stepJason Wessel2010-08-05
| | | | | | | | | | When an arch such as mips and microblaze does not implement either HW or software single stepping the debug core should re-enter kdb. The kdb code will properly ignore the single step operation. Attempting to single step the kernel without software or hardware support causes unpredictable kernel crashes.

* gdbstub: do not directly use dbg_reg_def[] in gdb_cmd_reg_set()Jason Wessel2010-08-05
| | | | | | | | | | | | | | | | | | | Presently the usable registers definitions on x86 are not contiguous for kgdb. The x86 kgdb uses a case statement for the sparse register accesses. The array which defines the registers (dbg_reg_def) should not be used directly in order to safely work with sparse register definitions. Specifically there was a problem when gdb accesses ORIG_AX, which is accessed only through the case statement. This patch encodes register memory using the size information provided from the debugger which avoids the need to look up the size of the register. The dbg_set_reg() function always further validates the inputs from the debugger. Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com>

* gdbstub: Optimize kgdb's "thread:" response for the gdb serial protocolJason Wessel2010-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | The gdb debugger understands how to parse short versions of the thread reference string as long as the bytes are paired in sets of two characters. The kgdb implementation was always sending 8 leading zeros which could be omitted, and further optimized in the case of non-negative thread numbers. The negative numbers are used to reference a specific cpu in the case of kgdb. An example of the previous i386 stop packet looks like: T05thread:00000000000003bb; New stop packet response: T05thread:03bb; The previous ThreadInfo response looks like: m00000000fffffffe,0000000000000001,0000000000000002,0000000000000003,0000000000000004,0000000000000005,0000000000000006,0000000000000007,000000000000000c,0000000000000088,000000000000008a,000000000000008b,000000000000008c,000000000000008d,000000000000008e,00000000000000d4,00000000000000d5,00000000000000dd New ThreadInfo response: mfffffffe,01,02,03,04,05,06,07,0c,88,8a,8b,8c,8d,8e,d4,d5,dd A few bytes saved means better response time when using kgdb over a serial line.

| * ARM: 6279/1: highmem: fix SMP preemption bug in kmap_high_l1_viptGary King2010-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smp_processor_id() must not be called from a preemptible context (this is checked by CONFIG_DEBUG_PREEMPT). kmap_high_l1_vipt() was doing so. This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth could be incremented, causing a BUG_ON(*depth <= 0); in kunmap_high_l1_vipt(). The solution is to move the call to smp_processor_id() after the call to preempt_disable().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the coherent DMA buffers are mapped as Normal Non-cacheable (ARM_DMA_MEM_BUFFERABLE enabled), buffer accesses are no longer ordered with Device memory accesses causing failures in device drivers that do not use the mandatory memory barriers before starting a DMA transfer. LKML discussions led to the conclusion that such barriers have to be added to the I/O accessors: http://thread.gmane.org/gmane.linux.kernel/683509/focus=686153 http://thread.gmane.org/gmane.linux.ide/46414 http://thread.gmane.org/gmane.linux.kernel.cross-arch/5250 This patch introduces a wmb() barrier to the write*() I/O accessors to handle the situations where Normal Non-cacheable writes are still in the processor (or L2 cache controller) write buffer before a DMA transfer command is issued. For the read*() accessors, a rmb() is introduced after the I/O to avoid speculative loads where the driver polls for a DMA transfer ready bit.

| | | | | | | | | | | | | | | | | | | | | | This patch is in preparation for a subsequent patch which adds barriers to the I/O accessors. Since the mandatory barriers may do an L2 cache sync, this patch avoids a recursive call into l2x0_cache_sync() via the write*() accessors and wmb() and a call into l2x0_cache_sync() with the l2x0_lock held.

I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages.

The second pass of the etr_work_fn will reset the eacr.es bit but will leave the clock_sync_word intact. Fix this race by moving the reset of the eacr.es bit into the switch-to-local and sync-check functions and by checking the eacr.es bit as well to decide if the clock needs to be synced.

| * | | [S390] Fix IRQ tracing in case of PERHeiko Carstens2010-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case user space is single stepped (PER) the program check handler claims too early that IRQs are enabled on the return path. Subsequent checks will notice that the IRQ mask in the PSW and what lockdep thinks the IRQ mask should be do not correlate and therefore will print a warning to the console and disable lockdep. Fix this by doing all the work within the correct context. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
