Srinivasan" Subject: [PATCH 00/10] Drivers: hv: vmbus: Enable kexec and other misc cleanup Date: Wed, 3 Jun 2015 12:31:37 -0700 Message-Id: <1433359897-31817-1-git-send-email-kys@microsoft.com> X-Mailer: git-send-email 1.7.4.1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org In addition to enabling kexec, this patch-set has a bunch of miscellaneous fixes. Alex Ng (1): Drivers: hv: balloon: Enable dynamic memory protocol negotiation with Windows 10 hosts K. Y. Srinivasan (1): Drivers: hv: vmbus: Permit sending of packets without payload Vitaly Kuznetsov (8): Loaded Hyper-V module will use these functions to disable CPU hotplug under certain circumstances. Convert cpu_hotplug_disabled to a counter (protected by cpu_add_remove_lock) to support e.g. disable -> disable -> enable call sequences. Commit e513229b4c38 ("Drivers: hv: vmbus: prevent cpu offlining on newer hypervisors") was altering smp_ops.cpu_disable to prevent CPU offlining. We can bo better by using cpu_hotplug_enable/disable functions instead of such hard-coding. Drivers: hv: vmbus: remove hv_synic_free_cpu() call from hv_synic_cleanup() Drivers: hv: vmbus: add special kexec handler Drivers: hv: don't do hypercalls when hypercall_page is NULL Drivers: hv: vmbus: use 'die' notification chain instead of 'panic' Drivers: hv: kvp: check kzalloc return value Drivers: hv: fcopy: dynamically allocate smsg_out in fcopy_send_data() Documentation/power/suspend-and-cpuhotplug.txt | 6 +- arch/x86/include/asm/mshyperv.h | 2 + arch/x86/kernel/cpu/mshyperv.c | 30 +++++++++ drivers/hv/channel.c | 3 +- drivers/hv/hv.c | 15 +++-- drivers/hv/hv_balloon.c | 26 ++++++-- drivers/hv/hv_fcopy.c | 21 ++++--- drivers/hv/hv_kvp.c | 3 + drivers/hv/vmbus_drv.c | 76 +++++++++--------------- kernel/cpu.c | 13 +++-- 10 files changed, 118 insertions(+), 77 deletions(-) -- 1.7.4.1
