install several missing uapi headers

2020-08-21T09:01:49Z

Commit fcc8487d477a3452a1d0ccbdd4c5e0e1e3cb8bed ("uapi: export all headers under uapi directories") changed the default to install all headers not marked to be conditional. This takes the list of headers listed in the commit message and manually adds an export for those that are already present in this kernel version. Found during an attempt to build mtd-utils 2.1.2 as it wants hash_info.h, which exists since 3.13 but has not been installed until the above mentioned commit, which ended up in 4.12.

KVM: PPC: Book3S HV: Save/restore XER in checkpointed register state

2017-01-09T07:32:22Z

commit 0d808df06a44200f52262b6eb72bcb6042f5a7c5 upstream. When switching from/to a guest that has a transaction in progress, we need to save/restore the checkpointed register state. Although XER is part of the CPU state that gets checkpointed, the code that does this saving and restoring doesn't save/restore XER. This fixes it by saving and restoring the XER. To allow userspace to read/write the checkpointed XER value, we also add a new ONE_REG specifier. The visible effect of this bug is that the guest may see its XER value being corrupted when it uses transactions.

powerpc/ptrace: Enable support for Performance Monitor registers

2016-08-01T01:15:24Z

This patch enables support for Performance monitor registers related ELF core note NT_PPC_PMU based ptrace requests through PTRACE_GETREGSET, PTRACE_SETREGSET calls. This is achieved through adding one new register sets REGSET_PMU in powerpc corresponding to the ELF core note sections added in this regard. It also implements the get, set and active functions for this new register sets added. Signed-off-by: Anshuman Khandual Signed-off-by: Simon Guo Signed-off-by: Michael Ellerman
