From bb8c29caffdda55d3df0315ff2485f7df7290b1d Mon Sep 17 00:00:00 2001 From: Heiko Carstens <heiko.carstens@de.ibm.com> Date: Tue, 7 Jul 2009 16:37:05 +0200 Subject: [S390] udelay: disable lockdep to avoid false positives Our udelay implementation enables interrupts to receive a special timer interrupt regardless of the context it is called from. This might lead to false positive lockdep reports. Since lockdep isn't aware of the fact that only a single interrupt source is enabled it warns about possible deadlocks that in reality won't happen, like the one below. To fix this disable lockdep before enabling interrupts.

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan

Carstens <heiko.carstens@de.ibm.com> Date: Fri, 24 Jul 2009 12:39:49 +0200 Subject: [S390] hibernation: fix lowcore handling Our swsusp_arch_suspend() backend implementation disables prefixing by setting the contents of the prefix register to 0. However afterwards common code functions are called which might access percpu data structures. Since the lowcore contains e.g. the percpu base pointer this isn't a good idea. So fix this by copying the hibernating cpu's lowcore to absolute address zero.

The vdso code switches to the access register mode to get access to the per-cpu data structure to execute the magic ectg instruction. After the ectg instruction the code always switches back to the primary mode but for noexec=on the correct mode is the secondary mode. The effect of the bug is that the user space program looses the access to all mappings without PROT_EXEC, e.g. the stack. The problem is fixed by restoring the mode that has been active before the switch to the access register mode.

Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

There are two options to fix the problem: o move all the s390 specific code to vcpu->wq and remove vcpu->arch.local_int.wq o move all the s390 specific code to vcpu->arch.local_int.wq This patch chooses the 2nd variant for two reasons: o s390 does not use kvm_vcpu_block but implements its own enabled wait handling. Having a separate wait_queue make it clear, that our wait mechanism is different o the patch is much smaller Report-by: Julia Lawall <julia@diku.dk> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com> --- arch/s390/kvm/interrupt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/s390') diff --git a/arch/s390/kvm/interrupt.c b/arch/s390/kvm/interrupt.c index f04f5301b1b4..4d613415c435 100644 --- a/arch/s390/kvm/interrupt.c +++ b/arch/s390/kvm/interrupt.c @@ -386,7 +386,7 @@ no_timer: } __unset_cpu_idle(vcpu); __set_current_state(TASK_RUNNING); - remove_wait_queue(&vcpu->wq, &wait); + remove_wait_queue(&vcpu->arch.local_int.wq, &wait); spin_unlock_bh(&vcpu->arch.local_int.lock); spin_unlock(&vcpu->arch.local_int.float_int->lock); hrtimer_try_to_cancel(&vcpu->arch.ckc_timer); -- cgit v1.2.3 From 677c1dd706d9cc384730cbd52baf821923d8be9b Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Date: Fri, 7 Aug 2009 10:39:24 +0200 Subject: [S390] kernel: Storing machine flags early in lowcore Currently, the machine_flags are stored late in the startup initialization which results in failing machine type checks (e.g. for MACHINE_IS_VM). To allow these checks, store the machine flags in the lowcore when the machine type has been detected.
