| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The abbreviation of severity should be SEV instead of SER, so the CPER severity constants are renamed accordingly. GHES severity constants are renamed in the same way too. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| * | | | arch/tile: don't validate CROSS_COMPILE needlesslyChris Metcalf2010-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, the arch/tile Makefile will only check for a valid combination of CROSS_COMPILE vs "uname -m" for a few common targets that are typically the ones we get wrong (vmlinux, all, and modules). The change handles the case of an empty "make" goal like "make all". Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org>

| * | | | | arch/tile: extend syscall ABI to set r1 on return as well.Chris Metcalf2010-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the tile architecture ABI for syscall return has just been that r0 holds the return value, and an error is only signalled like it is for kernel code, with a negative small number. However, this means that in multiple places in userspace we end up writing the same three-cycle idiom that tests for a small negative number for error. It seems cleaner to instead move that code into the kernel, and set r1 to hold zero on success or errno on failure; previously, r1 was just zeroed on return from the kernel (to avoid leaking kernel state). This way a single conditional branch after the syscall is sufficient to test for the failure case. The number of cycles taken is the same, but the error-checking code is in just one place, so total code size is smaller, and random userspace syscall code is easier to understand.

| * | | | | arch/tile: support backtracing on TILE-GxChris Metcalf2010-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This functionality was stubbed out until recently. Now we support our normal backtracing API on TILE-Gx as well as on TILE64/TILEPro. This change includes a tweak to the instruction encoding caused by adding addxli for compat mode.

Second, the C ABI requires a save area of two registers, not two pointers, since in compat mode we have 64-bit registers all of which we need to save, even though we only have 32-bit VAs.

| * | | | | arch/tile: Use separate, better minsec values for clocksource and sched_clock.Chris Metcalf2010-08-13

For the clock_event_device that's exactly right since it has a short maximum countdown time. But for sched_clock we want to avoid wraparound when converting from ticks to nsec over a much longer window, so we force a shift of 10. And for clocksource it seems dodgy to use a 5-sec minsec as well, so we copy some other platforms and force a shift of 22. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

But there were no users that needed the whole value until commit 424acaaeb3a3932d64a9b4bd59df6cf72c22d8f3 rwsem: wake queued readers when writer blocks on active read lock made this change: - (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK)) - /* Someone grabbed the sem already */ + rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS) + /* Someone grabbed the sem for write already */ RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked at the low order 32-bits. The new code needs to see all 64 bits. Signed-off-by: Tony Luck <tony.luck@intel.com>

In that case the storage for the 'in_crash_kexec' flag was never built. This version defines that flag as 0 if CONFIG_KEXEC is not set. The patch is tested with all combinations of those two options.

When invoking the crash kernel to write a dump, kdump_nmi_shootdown_cpus() uses NMI's to get all the cpu's to save their register context and halt. But the NMI interrupt handler runs a callback list. This patch sets a flag to prevent any of those callbacks from interfering with the halt of the cpu. For UV, which currently has the only callback to which this is relevant, the uv_handle_nmi() callback should not do dumping of stacks. The 'in_crash_kexec' flag is defined as an extern in kdebug.h firstly because x2apic_uv_x.c includes it. Secondly because some future callback might need the flag to know that it should not enter the debugger. (Such a scenario was in fact present in the 2.6.32 kernel, SuSE distribution, where a call to kdb needed to be avoided.)
