This is a note to let you know that I have just added a patch titled of/address: use atomic allocation in pci_register_io_range() to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.y-ckt4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From dcdb3ba49a2fb1e9eb4dccca6021f69578feb6cf Mon Sep 17 00:00:00 2001 From: Jingoo Han <jingoohan1@gmail.com> Date: Thu, 18 Jun 2015 00:12:27 +0900 Subject: of/address: use atomic allocation in pci_register_io_range() commit 294240ffe784e951dc2ef070da04fa31ef6db3a0 upstream. When kzalloc() is called under spin_lock(), GFP_ATOMIC should be used to avoid sleeping allocation. The call tree is: of_pci_range_to_resource() --> pci_register_io_range() <-- takes spin_lock(&io_range_lock); --> kzalloc() Signed-off-by: Jingoo Han <jingoohan1@gmail.com> Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Kamal Mostafa <kamal@canonical.com> --- drivers/of/address.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 1.9.1
