When the VPA is\nunregistered, or the VCPUs are cleaned up, these pages are released using\nput_page().\n\nHowever, the get_user_pages() is invoked on the specific memory are of the\nVPA which could lie within hugepages.

We just assume they\u0027re napping and we don\u0027t do anything\nto stop them trying to enter the kernel while the guest is running.\nThis means that a stray IPI can wake up the hardware thread and it will\nthen try to enter the kernel, but since the core is in guest context,\nit will execute code from the guest in hypervisor mode once it turns the\nMMU on, which tends to lead to crashes or hangs in the host.\n\nThis fixes the problem by adding two new one-byte flags in the\nkvmppc_host_state structure in the PACA which are used to interlock\nbetween the primary thread and the unused secondary threads when entering\nthe guest. With these flags, the primary thread can ensure that the\nunused secondaries are not already in kernel mode (i.e. handling a stray\nIPI) and then indicate that they should not try to enter the kernel\nif they do get woken for any reason.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

Thanks Stephen ! There\u0027s still some bits\n and pieces remaining if you do a grep -ir series arch/powerpc but\n they are harmless and will be removed in the next few weeks\n hopefully.\n\n - The \u0027fadump\u0027 functionality (Firmware Assisted Dump) replaces the\n previous (equivalent) \"pHyp assisted dump\"... it\u0027s a rewrite of a\n mechanism to get the hypervisor to do crash dumps on pSeries, the\n new implementation hopefully being much more reliable. Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely).
