   The Linux Kernel 3.15-RC7 is now available for the users, announced Linus Torvalds. This Linux Kernel version comes with plenty of fixes and improvements. This article will guide you to install or upgrade to Linux Kernel 3.15-RC7 in your Ubuntu or Linux Mint system.


Fixes

  • ACPI / thermal: fix workqueue destroy order
  • lift the "already marked killed" case into shrink_dentry_list()
  • split dentry_kill()
  • expand dentry_kill(dentry, 0) in shrink_dentry_list()
  • shrink_dentry_list(): take parent's ->d_lock earlier
  • dealing with the rest of shrink_dentry_list() livelock
  • dentry_kill() doesn't need the second argument now
  • MIPS: ptrace: Avoid smp_processor_id() in preemptible code
  • KVM: PPC: Book3S: ifdef on CONFIG_KVM_BOOK3S_32_HANDLER for 32bit
  • KVM guest: Make pv trampoline code executable
  • ARM: at91/dt: sam9260: correct external trigger value
  • ARM: at91: sam9260: fix compilation issues
  • ARM: trusted_foundations: fix compile error on non-SMP
  • pinctrl: vt8500: Ensure value reg is updated when setting direction
  • ARM: 8051/1: put_user: fix possible data corruption in put_user
  • dmaengine: dw: went back to plain {request,free}_irq() calls
  • Input: fix ps2/serio module dependency
  • Input: atmel-wm97xx - only build for AVR32
  • dmaengine: omap: hide filter_fn for built-in drivers
  • dmaengine: sa11x0: remove broken #ifdef and many more.
