2018-07-02powerpc/powernv/ioda2: Reduce upper limit for DMA window sizeAlexey Kardashevskiy
We use PHB in mode1 which uses bit 59 to select a correct DMA window. However there is mode2 which uses bits 59:55 and allows up to 32 DMA windows per a PE. Even though documentation does not clearly specify that, it seems that the actual hardware does not support bits 59:55 even in mode1, in other words we can create a window as big as 1<<58 but DMA simply won't work. This reduces the upper limit from 59 to 55 bits to let the userspace know about the hardware limits.

2018-07-02powerpc/pci: Remove legacy debug codeBreno Leitao
Commit 59f47eff03a0 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") removed the 'oirq' variable, but kept memsetting it when the DEBUG macro is defined. When setting DEBUG macro for debugging purpose, the kernel fails to build since 'oirq' is not defined anymore. This patch simply remove the debug block, since it does not seem to sense now.

2018-07-02scripts: Add ppc64le support for checkstack.plBreno Leitao
64-bit ELF v2 ABI specification for POWER describes, on section "General Stack Frame Requirements", that the stack should use the following instructions when compiled with backchain: mflr r0 std r0, 16(r1) stdu r1, -XX(r1) Where XX is the frame size for that function, and this is the value checkstack.pl will find the stack size for each function. This patch also simplifies the entire Powerpc section, since just two type of instructions are used, 'stdu' for 64 bits and 'stwu' for 32 bits platform.

2018-07-02powerpc: xmon: use ktime_get_coarse_boottime64Arnd Bergmann
get_monotonic_boottime() is deprecated, and may not be safe to call in every context, as it has to read a hardware clocksource. This changes xmon to print the time using ktime_get_coarse_boottime64() instead, which avoids the old timespec type and the HW access.

2018-07-02powerpc/eeh: Avoid misleading message "EEH: no capable adapters found"Mauro S. M. Rodrigues
Due to recent refactoring in EEH in: commit b9fde58db7e5 ("powerpc/powernv: Rework EEH initialization on powernv") a misleading message was seen in the kernel message buffer: [ 0.108431] EEH: PowerNV platform initialized [ 0.589979] EEH: No capable adapters found This happened due to the removal of the initialization delay for powernv platform. Even though the EEH infrastructure for the devices is eventually initialized and still works just fine the eeh device probe step is postponed in order to assure the PEs are created. Later pnv_eeh_post_init does the probe devices job but at that point the message was already shown right after eeh_init flow. This patch introduces a new flag EEH_POSTPONED_PROBE to represent that temporary state and avoid the message mentioned above and showing the follow one instead: [ 0.107724] EEH: PowerNV platform initialized [ 4.844825] EEH: PCI Enhanced I/O Error Handling Enabled Signed-off-by: Mauro S.

2018-07-02ocxl: Change return type for fault handlerSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t") There is an existing bug when vm_insert_pfn() can return ENOMEM which was ignored and VM_FAULT_NOPAGE returned as default. The new inline vmf_insert_pfn() has removed this inefficiency by returning correct vm_fault_ type.

2018-06-29sg: remove ->sg_magic memberJens Axboe
This was introduced more than a decade ago when sg chaining was added, but we never really caught anything with it. The scatterlist entry size can be critical, since drivers allocate it, so remove the magic member. Recently it's been triggering allocation stalls and failures in NVMe.

2018-06-29blk-mq: don't queue more if we get a busy returnJens Axboe
Some devices have different queue limits depending on the type of IO. A classic case is SATA NCQ, where some commands can queue, but others cannot. If we have NCQ commands inflight and encounter a non-queueable command, the driver returns busy. Currently we attempt to dispatch more from the scheduler, if we were able to queue some commands. But for the case where we ended up stopping due to BUSY, we should not attempt to retrieve more from the scheduler. If we do, we can get into a situation where we attempt to queue a non-queueable command, get BUSY, then successfully retrieve more commands from that scheduler and queue those. This can repeat forever, starving the non-queuable command indefinitely. Fix this by NOT attempting to pull more commands from the scheduler, if we get a BUSY return. This should also be more optimal in terms of letting requests stay in the scheduler for as long as possible, if we get a BUSY due to the regular out-of-tags condition.
