[PATCHv6 01/10] x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation

[PATCHv6 10/10] x86/mm: Allow to have userspace mappings above 47-bits

On x86, 5-level paging enables 56-bit userspace virtual address space. Not all user space is ready to handle wide addresses. It's known that at least some JIT compilers use higher bits in pointers to encode their information. It collides with valid pointers with 5-level paging and leads to

[RFC PATCH 0/2] remove CONFIG_MOVABLE_NODE

Hi, I am continuing to cleanup the memory hotplug code and CONFIG_MOVABLE_NODE seems dubious at best. The following two patches simply removes the flag and make it de-facto always enabled. The current semantic of the config option is twofold 1) it automatically binds hotplugable nodes to have

[PATCH] x86: Prevent uninitialized stack byte read in apply_alternatives()

In the current form of the code, if a->replacementlen is 0, the reference to *insnbuf for comparison touches potentially garbage memory. While it doesn't affect the execution flow due to the subsequent a->replacementlen comparison, it is (rightly) detected as use of uninitialized memory by a

Re: 4.9.28: VIA velocity hang: how to find cause?

Hello, This issue occurs on VIA Epia M910E. Both interfaces suffer from this. Setting msglvl with ethtool has no effect on the info the driver provides on any issues. So how to proceed from here? If this is a software issue, which I cannot determine, the driver is useless in its present state.
