A non-periodic clock_event_device and the "jiffies" clock don't mix well: tick_handle_periodic() can go into an infinite loop. Currently lguest guests use the jiffies clock when the TSC is unusable. Instead, make the Host write the current time into the lguest page on every interrupt. This doesn't cost much but is more precise and at least as accurate as the jiffies clock. It also gets rid of the GET_WALLCLOCK hypercall. Also, delay setting sched_clock until our clock is set up, otherwise the early printk timestamps can go backwards (not harmful, just ugly).

Jason Yeh sent his crashing .config: bzImages made with CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we crash with unusual results such as: lguest: unhandled trap 14 at 0xc0122ae1 (0xa9) Relying on BSS being zero was merely laziness on my part, and unfortunately, lguest doesn't go through the normal startup path (which does this in asm).

MXC needs the same change as IOP. See [ARM] 4494/1 or commit 7dea1b20 An undefined reference to elf_hwcap prevents linkage, due to changes made by f884b1cf and d1cbbd6b Removing processor.h removes the extern definition of elf_hwcap, which fixes the link issue, but forgets cpu_relax(). So, instead, we'll call barrier() directly.

If a machine check is pending and the external or I/O interrupt handler returns to userspace io_mcck_pending is going to call s390_handle_mcck. Before this happens a call to TRACE_IRQS_ON was already made since we know that we are going back to userspace and hence interrupts will be enabled. So there was an indication that interrupts are enabled while in reality they are still disabled. s390_handle_mcck will do a local_irq_save/restore pair and confuse lockdep which later complains about inconsistent irq tracing. To solve this just call trace_hardirqs_off before calling s390_handle_mcck and trace_hardirqs_on afterwards.

There is no need to disable bottom halves when holding call_lock. Also this could imply that it is legal to call smp_call_function* from bh context, which it is not.

BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of errors, starting with a parse error on the request_queue_t definition. Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the option back in to the block. Caught with a randconfig on sh.
