[PATCH AUTOSEL 4.14 1/9] 9p: virtio: make sure 'offs' is initialized in zc_request

by Sasha Levin

From: Dominique Martinet <asmadeus(a)codewreck.org> [ Upstream commit 4a73edab69d3a6623f03817fe950a2d9585f80e4 ] Similarly to the previous patch: offs can be used in handle_rerrors without initializing on small payloads; in this case handle_rerrors will not use it because of the size check, but it doesn't hurt to make sure it is zero to please scan-build. This fixes the following warning: net/9p/trans_virtio.c:539:3: warning: 3rd function call argument is an uninitialized value [core.CallAndMessage] handle_rerror(req, in_hdr_len, offs, in_pages); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reviewed-by: Simon Horman <simon.horman(a)corigine.com> Signed-off-by: Dominique Martinet <asmadeus(a)codewreck.org> Signed-off-by: Eric Van Hensbergen <ericvh(a)kernel.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- net/9p/trans_virtio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/9p/trans_virtio.c b/net/9p/trans_virtio.c index c6a46e8e9eda5..25f5caa57289b 100644 --- a/net/9p/trans_virtio.c +++ b/net/9p/trans_virtio.c @@ -401,7 +401,7 @@ p9_virtio_zc_request(struct p9_client *client, struct p9_req_t *req, struct page **in_pages = NULL, **out_pages = NULL; struct virtio_chan *chan = client->trans; struct scatterlist *sgs[4]; - size_t offs; + size_t offs = 0; int need_drop = 0; p9_debug(P9_DEBUG_TRANS, "virtio request\n"); -- 2.40.1

[PATCH v2 RESEND] tty/sysrq: replace smp_processor_id() with get_cpu()

by Muhammad Usama Anjum

The smp_processor_id() shouldn't be called from preemptible code. Instead use get_cpu() and put_cpu() which disables preemption in addition to getting the processor id.

[PATCH v3 1/2] ata: pata_falcon: fix IO base selection for Q40

by Michael Schmitz

With commit 44b1fbc0f5f3 ("m68k/q40: Replace q40ide driver with pata_falcon and falconide"), the Q40 IDE driver was replaced by pata_falcon.c. Both IO and memory resources were defined for the Q40 IDE platform device, but definition of the IDE register addresses was modeled after the Falcon case, both in use of the memory resources and in including register scale and byte vs. word offset in the address. This was correct for the Falcon case, which does not apply any address translation to the register addresses. In the Q40 case, all of device base address, byte access offset and register scaling is included in the platform specific ISA access translation (in asm/mm_io.h). As a consequence, such address translation gets applied twice, and register addresses are mangled. Use the device base address from the platform IO resource, and use standard register offsets from that base in order to calculate register addresses (the IO address translation will then apply the correct ISA window base and scaling). Encode PIO_OFFSET into IO port addresses for all registers except the data transfer register. Encode the MMIO offset there (pata_falcon_data_xfer() directly uses raw IO with no address translation).

But jiffies is only updated in the timer interrupt, so when kgdb_cpu_enter() begins to run there may already be nearly one rcu check period after jiffies. Since all interrupts are disabled during kgdb_cpu_enter(), jiffies will not be updated. When kgdb_cpu_enter() returns, rcu_state.jiffies_stall maybe already gets timeout. We can set rcu_state.jiffies_stall to two rcu check periods later, e.g. jiffies + (rcu_jiffies_till_stall_check() * 2) in rcu_cpu_stall_reset() to avoid this problem. But this isn't a complete solution because kgdb may take a very long time in irq disabled context. Instead, update jiffies at the beginning of rcu_cpu_stall_reset() can solve all kinds of problems [1]. But this causes a new problem because updating jiffies is not NMI safe while rcu_cpu_stall_reset() may be used in NMI context. So we don't update the global jiffies, but only add the time 'delta' to jiffies locally at the beginning of rcu_cpu_stall_reset() which has the same effect.
