This adds an initial dts for the Blueline (Pixel 3). Supported functionality includes Debug UART, UFS, USB-C (peripheral), USB-A (host), microSD-card and Bluetooth.

2020-02-10arm64: ssbs: Fix context-switch when SSBS is present on all CPUsWill Deacon
When all CPUs in the system implement the SSBS extension, the SSBS field in PSTATE is the definitive indication of the mitigation state. Further, when the CPUs implement the SSBS manipulation instructions (advertised to userspace via an HWCAP), EL0 can toggle the SSBS field directly and so we cannot rely on any shadow state such as TIF_SSBD at all. Avoid forcing the SSBS field in context-switch on such a system, and simply rely on the PSTATE register instead.

2020-02-04x86: mm: avoid allocating struct mm_struct on the stackSteven Price
struct mm_struct is quite large (~1664 bytes) and so allocating on the stack may cause problems as the kernel stack size is small. Since ptdump_walk_pgd_level_core() was only allocating the structure so that it could modify the pgd argument we can instead introduce a pgd override in struct mm_walk and pass this down the call stack to where it is needed. Since the correct mm_struct is now being passed down, it is now also unnecessary to take the mmap_sem semaphore because ptdump_walk_pgd() will now take the semaphore on the real mm.

2020-02-04mm: ptdump: reduce level numbers by 1 in note_page()Steven Price
Rather than having to increment the 'depth' number by 1 in ptdump_hole(), let's change the meaning of 'level' in note_page() since that makes the code simplier. Note that for x86, the level numbers were previously increased by 1 in commit 45dcd2091363 ("x86/mm/dump_pagetables: Fix printout of p4d level") and the comment "Bit 7 has a different meaning" was not updated, so this change also makes the code match the comment again.

2020-02-04arm64: mm: display non-present entries in ptdumpSteven Price
Previously the /sys/kernel/debug/kernel_page_tables file would only show lines for entries present in the page tables. However it is useful to also show non-present entries as this makes the size and level of the holes more visible. This aligns the behaviour with x86 which also shows holes.

2020-02-04arm64: mm: add p?d_leaf() definitionsSteven Price
walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arm64, we already have p?d_sect() macros which we can reuse for p?d_leaf(). pud_sect() is defined as a dummy function when CONFIG_PGTABLE_LEVELS < 3 or CONFIG_ARM64_64K_PAGES is defined. However when the kernel is configured this way then architecturally it isn't allowed to have a large page at this level, and any code using these page walking macros is implicitly relying on the page size/number of levels being the same as the kernel. So it is safe to reuse this for p?d_leaf() as it is an architectural restriction.

2020-02-04kbuild: rename hostprogs-y/always to hostprogs/always-yMasahiro Yamada
In old days, the "host-progs" syntax was used for specifying host programs. It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m) I think this makes more sense because a host program is always a host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.
