Linus Torvalds d8ea757b25 Xtensa improvements for 4.9: ... - add new kernel memory layouts for MMUv3 cores: with 256MB and 512MB KSEG size, starting at physical address other than 0; - make kernel load address configurable; - clean up kernel memory layout macros; - drop sysmem early allocator and switch to memblock; - enable kmemleak and memory reservation from the device tree; - wire up new syscalls: userfaultfd, membarrier, mlock2, copy_file_range, preadv2 and pwritev2; - add new platform: Cadence Configurable System Platform (CSP) and new core variant for it: xt_lnx; - rearrange CCOUNT calibration code, make most of it generic; - improve machine reset code (XTFPGA now reboots reliably with MMUv3 cores); - provide default memmap command line option for configurations without device tree support; - ISS fixes: simdisk is now capable of using highmem pages, panic correctly terminates simulator. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJX9RvtAAoJEFH5zJH4P6BEwmoQAJTUTrkRVd0nlTkh2vt8GfNR s0rGUnAZa2dm3EY+J7F7RFxDfcXHP5Z73iM0fm8mUt8V/f6NR4QEF1FB9BI0lqXy fTKHCgt+85BtPzIsNukwDi+QRyEtn3wFVCluKU4mtZ6KcEffTJwT0zMxrpDXoMdq gcoFGViSdQ0aNo1RosHUBCF/f34+cfUnvvmF8FhcnkAmTWniM+kWk0nDmGz+qInF ZWhvbcrPEEqR0j/wLLgL7kMhz1AYLI08+DaGR2UP80NQ9yuWraDfsRFnKbAHDqE0 JHAdcUQtPrQmBPSlc+CaE84sPXutsKVoZ/DKby70OR1TljrdytxnVC7zBvdgfVGd bWa7+qNdhSjGKtxwOPIvjOK5VJZYsFAI3SDEVW9pg0ZD3uBec+P1yWbh1Wvo+Geb X46EdlUfjsVp4U4G8CTG3aTQB8Dgn6QnkhtbI067l6evCebT21bx4Re1nPCfLD8C nlt1bgstVUuWDJt+2J0cGbMBill+RBtCEHEwsU778dqq7dJmiawg1aLI2kyHL6P5 VpBaprVrUHHZ5We0obl1BPyK1Sfc7L/NiaKv0wZbuAIoEjeEloYEB+q56HFz9NWn CJfcfugIh9q58842C0L0XY6uhce+7ZIpqTCMYFC6e8QjpJibY9qbORyineQy4Q7V QtGm6s1HFRCyvzpx2Uen =8HqU -----END PGP SIGNATURE----- Merge tag 'xtensa-20161005' of git://github.com/jcmvbkbc/linux-xtensa Pull Xtensa updates from Max Filippov: "Updates for the xtensa architecture.
