During boot we leave the idmap in place until paging_init, as we previously had to wait for the zero page to become allocated and accessible. Now that we have a statically-allocated zero page, we can uninstall the idmap much earlier in the boot process, making it far easier to spot accidental use of physical addresses. This also brings the cold boot path in line with the secondary boot path.

We currently open-code the removal of the idmap and restoration of the current task's MMU state in a few places. Before introducing yet more copies of this sequence, unify these to call a new helper, cpu_uninstall_idmap.

Currently the zero page is set up in paging_init, and thus we cannot use the zero page earlier. We use the zero page as a reserved TTBR value from which no TLB entries may be allocated (e.g. when uninstalling the idmap). To enable such usage earlier (as may be required for invasive changes to the kernel page tables), and to minimise the time that the idmap is active, we need to be able to use the zero page before paging_init. This patch follows the example set by x86, by allocating the zero page at compile time, in .bss. This means that the zero page itself is available immediately upon entry to start_kernel (as we zero .bss before this), and also means that the zero page takes up no space in the raw Image binary. The associated struct page is allocated in bootmem_init, and remains unavailable until this time. Outside of arch code, the only users of empty_zero_page assume that the empty_zero_page symbol refers to the zeroed memory itself, and that ZERO_PAGE(x) must be used to acquire the associated struct page, following the example of x86. This patch also brings arm64 inline with these assumptions.

We pass a size parameter to early_alloc and late_alloc, but these are only ever used to allocate single pages. In late_alloc we always allocate a single page. Both allocators provide us with zeroed pages (such that all entries are invalid), but we have no barriers between allocating a page and adding that page to existing (live) tables. A concurrent page table walk may see stale data, leading to a number of issues. This patch specialises the two allocators for page tables. The size parameter is removed and the necessary dsb(ishst) is folded into each. To make it clear that the functions are intended for use for page table allocation, they are renamed to {early,late}_pgtable_alloc, with the related function pointed renamed to pgtable_alloc. As the dsb(ishst) is now in the allocator, the existing barrier for the zero page is redundant and thus is removed. The previously missing include of barrier.h is added.

Currently __set_fixmap_offset is a macro function which has a local variable called 'addr'. If a caller passes a 'phys' parameter which is derived from a variable also called 'addr', the local variable will shadow this, and the compiler will complain about the use of an uninitialized variable. To avoid the issue with namespace clashes, 'addr' is prefixed with a liberal sprinkling of underscores. Turning __set_fixmap_offset into a static inline breaks the build for several architectures. Fixing this properly requires updates to a number of architectures to make them agree on the prototype of __set_fixmap (it could be done as a subsequent patch series).

Merge tag 'asoc-fix-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.5 A rather large batch of fixes here, almost all in the Intel driver. The changes that got merged in this merge window for Skylake were rather large and as well as issues that you'd expect in a large block of new code there were some problems created for older processors which needed fixing up. Things are largely settling down now hopefully.

This patch fixes vulnerability CVE-2016-2085. The problem exists because the vm_verify_hmac() function includes a use of memcmp(). Unfortunately, this allows timing side channel attacks; specifically a MAC forgery complexity drop from 2^128 to 2^12. This patch changes the memcmp() to the cryptographically safe crypto_memneq().

MMUv4 supports 2 concurrent page sizes: Normal and Super [4K to 16M] So far Linux supported a single super page size for a given Normal page, depending on the software page walking address split. e.g. we had 11:8:13 address split for 8K page, which meant super page was 2 ^(8+13) = 2M (given that THP size has to be PMD_SHIFT) Now we turn this around, by allowing multiple Super Pages in Kconfig (currently 2M and 16M only) and forcing page walker address split to PGDIR_SHIFT and PAGE_SHIFT For configs without Super page, things are same as before and PGDIR_SHIFT can be hacked to get non default address split The motivation for this change is a customer who needs 16M super page and a 8K Normal page combo.
