[PATCH] drm/lease: Send a distinct uevent

by Daniel Vetter

Sending the exact same hotplug event is not great uapi. Luckily the only already merged implementation of leases (in the -modesetting driver) doesn't care about what kind of uevent it gets, and unconditionally processes both hotplug and lease changes. So we can still adjust the uapi here. But e.g. weston tries to filter stuff, and I guess others might want to do that too. Try to make that possible. Cc: stable since it's uapi adjustement that we want to roll out everywhere.

[tip:efi/core] x86/efi: Allocate e820 buffer before calling efi_exit_boot_service

by tip-bot for Eric Snowberg

Commit-ID: b84a64fad40637b1c9fa4f4dbf847a23e29e672b Gitweb: https://git.kernel.org/tip/b84a64fad40637b1c9fa4f4dbf847a23e29e672b Author: Eric Snowberg <eric.snowberg(a)oracle.com> AuthorDate: Thu, 29 Nov 2018 18:12:20 +0100 Committer: Ingo Molnar <mingo(a)kernel.org> CommitDate: Fri, 30 Nov 2018 08:30:07 +0100 x86/efi: Allocate e820 buffer before calling efi_exit_boot_service The following commit: d64934019f6c ("x86/efi: Use efi_exit_boot_services()") introduced a regression on systems with large memory maps causing them to hang on boot. The first "goto get_map" that was removed from exit_boot() ensured there was enough room for the memory map when efi_call_early(exit_boot_services) was called. This happens when (nr_desc > ARRAY_SIZE(params->e820_table). Chain of events: exit_boot() efi_exit_boot_services() efi_get_memory_map <- at this point the mm can't grow over 8 desc priv_func() exit_boot_func() allocate_e820ext() <- new mm grows over 8 desc from e820 alloc efi_call_early(exit_boot_services) <- mm key doesn't match so retry efi_call_early(get_memory_map) <- not enough room for new mm system hangs This patch allocates the e820 buffer before calling efi_exit_boot_services() and fixes the regression.

[PATCH 1/2] tracepoint: Use __idx instead of idx in DO_TRACE macro to make it unique

by Steven Rostedt

From: Zenghui Yu <yuzenghui(a)huawei.com> After enabling KVM event tracing, almost all of trace_kvm_exit()'s printk shows "kvm_exit: IRQ: ..." even if the actual exception_type is NOT IRQ. More specifically, trace_kvm_exit() is defined in virt/kvm/arm/trace.h by TRACE_EVENT. This slight problem may have existed after commit e6753f23d961 ("tracepoint: Make rcuidle tracepoint callers use SRCU"). There are two variables in trace_kvm_exit() and __DO_TRACE() which have the same name, *idx*. Thus the actual value of *idx* will be overwritten when tracing. Fix it by adding a simple prefix.

[PATCH] arm64: ftrace: Fix to enable syscall events on arm64

by Masami Hiramatsu

Since commit 4378a7d4be30 ("arm64: implement syscall wrappers") introduced "__arm64_" prefix to all syscall wrapper symbols in sys_call_table, syscall tracer can not find corresponding metadata from syscall name. In the result, we have no syscall ftrace events on arm64 kernel, and some bpf testcases are failed on arm64. To fix this issue, this introduces custom arch_syscall_match_sym_name() which skips first 8 bytes when comparing the syscall and symbol names.
