2016-03-12ARC: [BE] readl()/writel() to work in Big Endian CPU configurationLada Trimasova
read{l,w}() write{l,w}() primitives should use le{16,32}_to_cpu() and cpu_to_le{16,32}() respectively to ensure device registers are read correctly in Big Endian CPU configuration. Per Arnd Bergmann | Most drivers using readl() or readl_relaxed() expect those to perform byte | swaps on big-endian architectures, as the registers tend to be fixed endian This was needed for getting UART to work correctly on a Big Endian ARC.

2016-03-11powerpc/8xx: Map linear kernel RAM with 8M pagesChristophe Leroy
On a live running system (VoIP gateway for Air Trafic Control), over a 10 minutes period (with 277s idle), we get 87 millions DTLB misses and approximatly 35 secondes are spent in DTLB handler. This represents 5.8% of the overall time and even 10.8% of the non-idle time. Among those 87 millions DTLB misses, 15% are on user addresses and 85% are on kernel addresses. And within the kernel addresses, 93% are on addresses from the linear address space and only 7% are on addresses from the virtual address space. MPC8xx has no BATs but it has 8Mb page size. This patch implements mapping of kernel RAM using 8Mb pages, on the same model as what is done on the 40x. In 4k pages mode, each PGD entry maps a 4Mb area: we map every two entries to the same 8Mb physical page. In each second entry, we add 4Mb to the page physical address to ease life of the FixupDAR routine. This is just ignored by HW. In 16k pages mode, each PGD entry maps a 64Mb area: each PGD entry will point to the first page of the area. The DTLB handler adds the 3 bits from EPN to map the correct page. With this patch applied, we now get only 13 millions TLB misses during the 10 minutes period. The idle time has increased to 313s and the overall time spent in DTLB miss handler is 6.3s, which represents 1% of the overall time and 2.2% of non-idle time.

2016-03-11PCI: thunder: Add driver for ThunderX-pass{1,2} on-chip devicesDavid Daney
The cavium,pci-thunder-ecam devices are exactly ECAM-based PCI root complexes. These root complexes (loosely referred to as ECAM units in the hardware manuals) are used to access the Thunder on-chip devices. They are special in that all the BARs on devices behind these root complexes are at fixed addresses. Add a driver for these devices that synthesizes Enhanced Allocation (EA) capability entries for each BAR. Since this EA synthesis is needed for exactly two chip models, we can hard- code some assumptions about the device topology and the layout of the config space of specific DEVFNs in the driver.
