PSW restart can be triggered on offline CPUs. If this happens, currently the PSW restart code fails, because functions like smp_processor_id() do not work on offline CPUs. This patch fixes this as follows: If PSW restart is triggered on an offline CPU, the PSW restart (sigp restart) is done a second time on another CPU that is online and the old CPU is stopped afterwards.

The rcu page table free code uses a couple of bits in the page table pointer passed to tlb_remove_table to discern the different page table types. __tlb_remove_table extracts the type with an incorrect mask which leads to memory leaks. The correct mask is ((FRAG_MASK << 4) | FRAG_MASK). Cc: stable@kernel.org Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

git commit 5e9a2692 "[S390] ptrace cleanup" introduced a regression for the case when both a user PER set (e.g. a storage alteration trace) and PTRACE_SINGLESTEP are active. The new code will overrule the user PER set with a instruction-fetch PER set over the whole address space for ptrace single stepping. The inferior process will be stopped after each instruction with an instruction fetch event. Any other events that may have occurred concurrently are not reported (e.g. storage alteration event) because the control bits for them are not set. The solution is to merge the PER control bits of the user PER set with the PER_EVENT_IFETCH control bit for PTRACE_SINGLESTEP.

This was found by inspection while tracking a similar bug in compat_statfs64, that has been fixed in mainline since decemeber. - This fixes a bug where not all of the f_spare fields were cleared on mips and s390. - Add the f_flags field to struct compat_statfs - Copy f_flags to userspace in case someone cares. - Use __clear_user to copy the f_spare field to userspace to ensure that all of the elements of f_spare are cleared. On some architectures f_spare is has 5 ints and on some architectures f_spare only has 4 ints. Which makes the previous technique of clearing each int individually broken. I don't expect anyone actually uses the old statfs system call anymore but if they do let them benefit from having the compat and the native version working the same. Signed-off-by: NEric W.

The current h8300 GPIO implementation doesn't provide the standard GPIO API, and in fact provides only direction control rather than normal GPIO functionality. Currently this is only used by the platform interrupt implementation rather than by a range of drivers so in preparation for moving over to gpiolib move the header out of the way of the gpiolib header, allowing a default GPIO implementation to be provided. For actual use of these GPIOs with gpiolib a real driver would still need to be written but there appears to be no current need for this.

When compiling an i386_defconfig kernel with gcc-4.6.1-9.fc15.i686, I noticed a warning about the asm operand for test_bit in kprobes' can_boost. I discovered that this caused only the first long of twobyte_is_boostable[] to be output. Jakub filed and fixed gcc PR50571 to correct the warning and this output issue. But to solve it for less current gcc, we can make kprobes' twobyte_is_boostable[] non-const, and it won't be optimized out.
