2012-10-20arm64: fix alignment padding in assembly codeMarc Zyngier
An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.

2012-10-20perf/x86: Disable uncore on virtualized CPUsYan, Zheng
Initializing uncore PMU on virtualized CPU may hang the kernel. This is because kvm does not emulate the entire hardware. Thers are lots of uncore related MSRs, making kvm enumerate them all is a non-trival task. So just disable uncore on virtualized CPU.

2012-10-19xen/x86: don't corrupt %eip when returning from a signal handlerDavid Vrabel
In 32 bit guests, if a userspace process has %eax == -ERESTARTSYS (-512) or -ERESTARTNOINTR (-513) when it is interrupted by an event /and/ the process has a pending signal then %eip (and %eax) are corrupted when returning to the main process after handling the signal. The application may then crash with SIGSEGV or a SIGILL or it may have subtly incorrect behaviour (depending on what instruction it returned to). The occurs because handle_signal() is incorrectly thinking that there is a system call that needs to restarted so it adjusts %eip and %eax to re-execute the system call instruction (even though user space had not done a system call). If %eax == -514 (-ERESTARTNOHAND (-514) or -ERESTART_RESTARTBLOCK (-516) then handle_signal() only corrupted %eax (by setting it to -EINTR). This may cause the application to crash or have incorrect behaviour. handle_signal() assumes that regs->orig_ax >= 0 means a system call so any kernel entry point that is not for a system call must push a negative value for orig_ax. For example, for physical interrupts on bare metal the inverse of the vector is pushed and page_fault() sets regs->orig_ax to -1, overwriting the hardware provided error code. xen_hypervisor_callback() was incorrectly pushing 0 for orig_ax instead of -1. Classic Xen kernels pushed %eax which works as %eax cannot be both non-negative and -RESTARTSYS (etc.), but using -1 is consistent with other non-system call entry points and avoids some of the tests in handle_signal(). There were similar bugs in xen_failsafe_callback() of both 32 and 64-bit guests. If the fault was corrected and the normal return path was used then 0 was incorrectly pushed as the value for orig_ax.

2012-10-18arm64: ptrace: use HW_BREAKPOINT_EMPTY type for disabled breakpointsWill Deacon
If a debugger tries to zero a hardware debug control register, the kernel will try to infer both the type and length of the breakpoint in order to sanity-check against the requested regset type. This will fail because the encoding will appear as a zero-length breakpoint. This patch changes the control register setting so that disabled breakpoints are treated as HW_BREAKPOINT_EMPTY and no further sanity-checking is required.

2012-10-18arm64: No need to set the x0-x2 registers in start_thread()Catalin Marinas
For historical reasons, ARM used to set r0-r2 in start_thread() to the first values on the user stack when starting a new user application. The same logic has been inherited in AArch64. The x0 register is overridden by the sys_execve() return value so it's always zero on success. The x1 and x2 registers are ignored by AArch64 and EABI AArch32 applications, so we can safely remove the register setting for both native and compat user space. This also fixes a potential fault with the kernel accessing user space stack directly. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Reported-by: Al Viro <viro@zeniv.linux.org.uk>

2012-10-18s390/cache: fix data/instruction cache outputHeiko Carstens
The sysfs and procfs output of the instruction and data caches were wrong: the output of the data cache provided that instruction cache values and vice versa. Fix this by using the correct type indication when issueing the ecag instruction.

2012-10-18s390: fix linker script for 31 bit buildsHeiko Carstens
Because of a change in the s390 arch backend of binutils (commit 23ecd77 "Pick the default arch depending on the target size" in binutils repo) 31 bit builds will fail since the linker would now try to create 64 bit binary output. Fix this by setting OUTPUT_ARCH to s390:31-bit instead of s390. Thanks to Andreas Krebbel for figuring out the issue. Fixes this build error: LD init/built-in.o s390x-4.7.2-ld: s390:31-bit architecture of input file `arch/s390/kernel/head.o' is incompatible with s390:64-bit output Cc: Andreas Krebbel <Andreas.Krebbel@de.ibm.com> Cc: stable@vger.kernel.org Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2012-10-18ARM: 7556/1: perf: fix updated event period in response to PERF_EVENT_IOC_PERIODWill Deacon
The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the sample period of a running perf_event. Consequently, when calculating the next event period, the new period will only be considered after the previous one has overflowed. This patch changes the calculation of the remaining event ticks so that they are offset if the period has changed.
