2017-11-07x86/mm: Add DMA support for SEV memory encryptionTom Lendacky
DMA access to encrypted memory cannot be performed when SEV is active. In order for DMA to properly work when SEV is active, the SWIOTLB bounce buffers must be used.

2017-11-07x86/mm, resource: Use PAGE_KERNEL protection for ioremap of memory pagesTom Lendacky
In order for memory pages to be properly mapped when SEV is active, it's necessary to use the PAGE_KERNEL protection attribute as the base protection. This ensures that memory mapping of, e.g. ACPI tables, receives the proper mapping attributes.

2017-11-07kprobes, x86/alternatives: Use text_mutex to protect smp_alt_modulesZhou Chengming
We use alternatives_text_reserved() to check if the address is in the fixed pieces of alternative reserved, but the problem is that we don't hold the smp_alt mutex when call this function. So the list traversal may encounter a deleted list_head if another path is doing alternatives_smp_module_del(). One solution is that we can hold smp_alt mutex before call this function, but the difficult point is that the callers of this functions, arch_prepare_kprobe() and arch_prepare_optimized_kprobe(), are called inside the text_mutex. So we must hold smp_alt mutex before we go into these arch dependent code. But we can't now, the smp_alt mutex is the arch dependent part, only x86 has it. Maybe we can export another arch dependent callback to solve this. But there is a simpler way to handle this problem. We can reuse the text_mutex to protect smp_alt_modules instead of using another mutex. And all the arch dependent checks of kprobes are inside the text_mutex, so it's safe now.

2017-11-07x86/build: Factor out fdimage/isoimage generation commands to standalone scriptChangbin Du
The build messages for fdimage/isoimage generation are pretty unstructured, just the raw shell command blocks are printed. Emit shortened messages similar to existing kbuild messages, and move the Makefile commands into a separate shell script - which is much easier to handle. This patch factors out the commands used for fdimage/isoimage generation from arch/x86/boot/Makefile to a new script arch/x86/boot/genimage.sh. Then it adds the new kbuild command 'genimage' which invokes the new script. All fdimages/isoimage files are now generated by a call to 'genimage' with different parameters. Now 'make isoimage' becomes: ...

2017-11-07selftests/x86/ldt_get: Add a few additional tests for limitsAndy Lutomirski
We weren't testing the .limit and .limit_in_pages fields very well. Add more tests. This addition seems to trigger the "bits 16:19 are undefined" issue that was fixed in an earlier patch. I think that, at least on my CPU, the high nibble of the limit ends in LAR bits 16:19.

2017-11-07selftests/x86/ldt_gdt: Robustify against set_thread_area() and LAR odditiesAndy Lutomirski
Bits 19:16 of LAR's result are undefined, and some upcoming improvements to the test case seem to trigger this. Mask off those bits to avoid spurious failures. commit 5b781c7e317f ("x86/tls: Forcibly set the accessed bit in TLS segments") adds a valid case in which LAR's output doesn't quite agree with set_thread_area()'s input. This isn't triggered in the test as is, but it will be if we start calling set_thread_area() with the accessed bit clear. Work around this discrepency. I've added a Fixes tag so that -stable can pick this up if neccesary.

2017-11-07x86/MCE/AMD: Always give panic severity for UC errors in kernel contextYazen Ghannam
The AMD severity grading function was introduced in kernel 4.1. The current logic can possibly give MCE_AR_SEVERITY for uncorrectable errors in kernel context. The system may then get stuck in a loop as memory_failure() will try to handle the bad kernel memory and find it busy. Return MCE_PANIC_SEVERITY for all UC errors IN_KERNEL context on AMD systems. After: b2f9d678e28c ("x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries") was accepted in v4.6, this issue was masked because of the tail-end attempt at kernel mode recovery in the #MC handler. However, uncorrectable errors IN_KERNEL context should always be considered unrecoverable and cause a panic.

Kept this commit separate from the re-tabulation changes, to make the changes easier to review: - add better explanation for entries with no explanation - fix/enhance the text of some of the entries - fix the vertical alignment of some of the feature number definitions - fix inconsistent capitalization - ... and lots of other small details i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.

2017-11-07x86/cpufeatures: Re-tabulate the X86_FEATURE definitionsIngo Molnar
Over the years asm/cpufeatures.h has become somewhat of a mess: the original tabulation style was too narrow, while x86 feature names also kept growing in length, creating frequent field width overflows. Re-tabulate it to make it wider and easier to read/modify. Also harmonize the tabulation of the other defines in this file to match it.
