This is subarch update for ES7000. I've modified platform check code and removed unnecessary OEM table parsing for newer systems that don't use OEM information during boot. Parsing the table in fact is causing problems, and the platform doesn't get recognized. The patch only affects the ES7000 subach. Signed-off-by: <Natalie.Protasevich@unisys.com> Signed-off-by:

The VIA VT8237's IOAPIC sends 'APIC De-Assert Messages' by default, causing another CPU interrupt when the IRQ pin is de-asserted. This feature is switched off by the patch to get rid of doubled ioapic level interrupt rates. Signed-off-by:

i386 generic subarchitecture requires explicit dmi strings or command line to enable bigsmp mode. The patch below removes that restriction, and uses bigsmp as soon as it finds more than 8 logical CPUs, Intel processors and xAPIC support. Signed-off-by:

o With introduction of kexec as boot-loader, the assumption that parameter segment will always be loaded at lower address than kernel and will be addressable by early bootup page tables is no longer valid. In kexec on panic case parameter segment might well be loaded beyond kernel image and might not be addressable by early boot page tables. o This case might hit in the scenario where user has reserved a chunk of memory for second kernel, for example 16MB to 64MB, and has also built second kernel for physical memory location 16MB. In this case kexec has no choice but to load the parameter segment at a higher address than new kernel image at safe location where new kernel does not stomp it. o Though problem should automatically go away once relocatable kernel for i386 is in place and kexec can determine the location of new kernel at run time and load parameter segment at lower address than kernel image. But till then this patch can go in (assuming it does not break something else). o This patch moves up the boot parameter saving code. Now boot parameters are copied out in protected mode before page tables are initialized. This will ensure that parameter segment is always addressable irrespective of its physical location.

If the virtual 86 machine reaches an instruction which raises a General Protection Fault (such as CLI or STI), the instruction is emulated (in handle_vm86_fault). However, the emulation ignored the TF bit, so the hardware debug interrupt was not invoked after such an emulated instruction (and the DOS debugger missed it). This patch fixes the problem by emulating the hardware debug interrupt as the last action before control is returned to the VM86 program. Signed-off-by:

The memory descriptors that comprise the EFI memory map are not fixed in stone such that the size could change in the future. This uses the memory descriptor size obtained from EFI to iterate over the memory map entries during boot. This enables the removal of an x86 specific pad (and ifdef) in the EFI header. I also couldn't stomach the broken up nature of the function to put EFI runtime calls into virtual mode any longer so I fixed that up a bit as well. For reference, this patch only impacts x86.

Only use read_timer_tsc only when CPU has TSC. Thanks to Andrea for pointing this out. Should not be issue on any platforms as all recent systems that has HPET also has CPUs that supports TSC. The patch is still required for correctness. Signed-off-by:

This patch pushes the creation of a rare signal frame (SIGBUS or SIGSEGV) into a separate function, thus saving stackspace in the main do_page_fault() stackframe. The effect is 132 bytes less of stack used by the typical do_page_fault() invocation - resulting in a denser cache-layout. (Another minor effect is that in case of kernel crashes that come from a pagefault, we add less space to the already existing frame, giving the crash functions a slightly higher chance to do their stuff without overflowing the stack.) (The changes also result in slightly cleaner code.) argument bugfix from "Guillaume C." <guichaz@gmail.com> Signed-off-by:

Use msleep_interruptible() instead of schedule_timeout() in ppc64-specific code to cleanup/simplify the sleeping logic. Change the units of the parameter of do_event_scan_all_cpus() to milliseconds from jiffies. The return value of rtas_extended_busy_delay_time() was incorrectly being used as a jiffies value (it is actually milliseconds), which is fixed by using the value as a parameter to msleep_interruptible(). Also, use rtas_extended_busy_delay_time() in another case where similar logic is duplicated. Signed-off-by:

We need to indicate to the hypervisor that it needs to save our VMX registers when switching partitions on a shared-processor system, just as it needs to for FP and PMC registers. This could be made to be on-demand when VMX is used, but we don't do that for FP nor PMC right now either so let's not overcomplicate things. Signed-off-by:
