2020-08-24kvm: mmu: page_track: Fix RCU list API usageMadhuparna Bhowmik1-2/+4
Use hlist_for_each_entry_srcu() instead of hlist_for_each_entry_rcu() as it also checkes if the right lock is held. Using hlist_for_each_entry_rcu() with a condition argument will not report the cases where a SRCU protected list is traversed using rcu_read_lock(). Hence, use hlist_for_each_entry_srcu().

2020-08-25powerpc/nx: Don't pack struct coprocessor_request_blockOliver O'Halloran1-2/+4
Building with W=1 results in the following warning: In file included from arch/powerpc/platforms/powernv/vas-fault.c:16: ./arch/powerpc/include/asm/icswx.h:159:1: error: alignment 1 of ‘struct coprocessor_request_block’ is less than 16 [-Werror=packed-not-aligned] 159 | } __packed; | ^ ./arch/powerpc/include/asm/icswx.h:159:1: error: alignment 1 of ‘struct coprocessor_request_block’ is less than 16 [-Werror=packed-not-aligned] ./arch/powerpc/include/asm/icswx.h:159:1: error: alignment 1 of ‘struct coprocessor_request_block’ is less than 16 [-Werror=packed-not-aligned] ./arch/powerpc/include/asm/icswx.h:159:1: error: alignment 1 of ‘struct coprocessor_request_block’ is less than 16 [-Werror=packed-not-aligned] cc1: all warnings being treated as errors This happens because coprocessor_request_block includes several sub-structures with an alignment specified using the __aligned(XX) attribute. The problem comes from coprocessor_request_block having the __packed attribute. Packing the structure causes the preferred alignment of the nested structures to be ignored and we get the warnings as a result. This isn't a problem in practice since the struct is defined with explicit padding in the form of reserved fields, but we'd like to get rid of the spurious warnings. The simplest solution is to remove the packed attribute and use a BUILD_BUG_ON() to ensure the struct is the correct (expected by HW) size compile time. Also add a __aligned(128) to the request block structure since Book4 for P8 suggests the HW requires it to be aligned to a 128 byte boundary. There's a similar requirement for P9 since the COPY and PASTE instructions used to invoke VAS/NX accelerators operates on a cache line boundary.

Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on the imx7d-zii-rmu2 board.

However, because the PHY driver was also broken, nobody noticed and it worked.

RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM
