Changes since v2: - Get rid of #ifdefs in mshyperv.c [Olaf Hering, Greg KH] PATCH 2/5 is added to support the change. - Fix (also broken) kdump [K. Y. Srinivasan] PATCH 5/5 added. Changes since v1: - rebased on top of current Greg's char-misc-next tree. To make general-purpose kexec (not just kdump) possible for Hyper-V guests we need to perform some additional cleanup before starting new kernel (see [PATCH 3/5] for the detailed description). Kdump also requires some mandatory cleanup [PATCH 5/5] Know limitations: kexec with balloned out memory is not possible as the newly loaded kernel doesn't know about this memory and there is no way to ask the host to bring all the memory back on cleanup (or at least I'm not aware of such a way). Kexec with hotplugged memory leads to reboot (not exactly sure why). Vitaly Kuznetsov (5): Drivers: hv: vmbus: remove hv_synic_free_cpu() call from hv_synic_cleanup() kexec: define kexec_in_progress in !CONFIG_KEXEC case Drivers: hv: vmbus: add special kexec handler Drivers: hv: don't do hypercalls when hypercall_page is NULL Drivers: hv: vmbus: add special crash handler arch/x86/include/asm/mshyperv.h | 4 ++++ arch/x86/kernel/cpu/mshyperv.c | 46 +++++++++++++++++++++++++++++++++++++++++ drivers/hv/hv.c | 15 +++++++------- drivers/hv/vmbus_drv.c | 29 ++++++++++++++++++++++++++ include/linux/kexec.h | 1 + 5 files changed, 88 insertions(+), 7 deletions(-) -- 2.4.2
