| | | | | | | | | | | | | | | | | | | | | | | | | | If the last block of the HSA is read, EVSTATE_ALL_STORED is returned by SCLP. Because of a missing break in the switch statement two trace entries are written in this case: "all stored" and "part stored". This patch adds the missing break and also adds a "fall through" comment to improve the readability.

After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.

The active ingredient of that patch is the conversion from a udelay(10) to a udelay(1) in the busy-wait loop of waiting for the forcewake acknowledge. If we restore that udelay(10) or insert another udelay(1) afterwards (or any wait longer than 250ns) everything works again. An alternative is also to remove any delay from the busy-wait loop. Given that in the atomic sections we want to complete the wait as quick as possible to avoid blocking the CPU for too long, it makes sense to remove the delay altogether and simply spin on the exit condition until it completes. So we replace the udelay(1) with cpu_relax().

This little dragon lair exploded the first time around when we've refactored the code a bit to use the common wait_for_atomic_us in "drm/i915: Group the GT routines together in both code and vtable", which caused QA to file fdo bug #51738. Chris Wilson entertained a few approaches to fixing #51738: Replacing the udelay(1) with the previously-used udelay(10) (or any other "sufficiently larger" delay), adding a posting read, or ditching the delay completely and using cpu_relax. We went with the cpu_relax and "915: Workaround hang with BSD and forcewake on SandyBridge". Which blew up in fdo bug #52424, but adding the posting read while still using cpu_relax seems to also fix that, it looks like the posting read is the important ingriedient to fix these rc6 related hangs on snb. Popular theories as to why this is like it is include: - A herd of pink elephants got royally angered somehow. - The gpu has internally different functional units and judging by the register offsets, the forcewake request register and the forcewake ack registers are _not_ in the same functional unit (or at least aren't reached through the same routes). Hence the posting read syncs up with the wrong block and gets the entire gpu confused. - ... As a minimal ducttape fix for 3.6, let's just put these posting reads into place again. We can try fancier approaches (like adding back the cpu_relax instead of the udelay) in -next.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

It really shouldn't do this to validate the kernel's own behavior because the user can corrupt it to be any value at all. From Daniel Borkmann. 5) Fix TCP metrics leak on netns dismantle, from Eric Dumazet. 6) Orphan the anonymous TCP socket from the SKB in ip_send_unicast_reply() so that the rest of the stack needn't see it. Otherwise we get selinux problems of all sorts, from Eric Dumazet. This is the best way to fix this since the socket is just a place holder for sending packets in a context where we have no real socket at all. 7) Fix TUN detach crashes, from Stanislav Kinsbursky. 8) dev_set_alias() leaks memory on krealloc() failure, from Alexey Khoroshilov. 9) FIB trie must use call_rcu() not call_rcu_bh(), because this code is not universally invoked from software interrupts.

This is a flawed behaviour - each function should only be responsible for its own bit. Since this registers are handled during the load/unload routines, this cleanup is removed altogether.

This patch resolves this, as well as fixing the flow for hypervisors which disable flr capabilities from functions as they pass them as PDA to VMs, as we cannot base the flow on the pci configuration space.

Below is sequence, which leads to oops for non-persistent devices: tun_chr_close() tun_detach() <== tun->socket.file = NULL tun_free_netdev() sk_release_sock() sock_release(sock->file == NULL) iput(SOCK_INODE(sock)) <== dereference on NULL pointer This patch just removes zeroing of socket's file from __tun_detach(). sock_release() will do this.
