[PATCH 2/4] context_tracking: Switch to new static_branch API

[PATCH 4/4] x86/entry/64: Bypass enter_from_user_mode on non-context-tracking boots

On CONFIG_CONTEXT_TRACKING kernels that have context tracking disabled at runtime (which includes most distro kernels), we still have the overhead of a call to enter_from_user_mode in interrupt and exception entries. If jump labels are available, this uses the jump label infrastructure to skip

[PATCH 1/4] x86/entry/64: Fix irqflag tracing wrt context tracking

Paolo pointed out that enter_from_user_mode could be called while irqflags were traced as though IRQs were on. In principle, this could confuse lockdep. It doesn't cause any problems that I've seen in any configuration, but if I build with CONFIG_DEBUG_LOCKDEP=y, enable a nohz_full CPU, and add

[PATCH 3/4] x86/asm: Add asm macros for static keys/jump labels

Unfortunately, these only work if HAVE_JUMP_LABEL. In principle, we could do some serious surgery on the core jump label infrastructure to keep the patch infrastructure available on x86 on all builds, but that's probably not worth it. Signed-off-by: Andy Lutomirski ---

[PATCH v3 06/11] staging: fsl-mc: Changed DPRC built-in portal's mc_io to be atomic

The DPRC built-in portal's mc_io is used to send commands to the MC to program MSIs for MC objects. This is done by the fsl_mc_msi_write_msg() callback, which is invoked by the generic MSI layer with interrupts disabled. As a result, the mc_io used in fsl_mc_msi_write_msg needs to be an atomic

[PATCH v3 05/11] staging: fsl-mc: Extended MC bus allocator to include IRQs

All the IRQs for DPAA2 objects in the same DPRC must use the ICID of that DPRC, as their device Id in the GIC-ITS. Thus, all these IRQs must share the same ITT table in the GIC. As a result, a pool of IRQs with the same device Id must be preallocated per DPRC (fsl-mc bus instance). So, the fsl-mc
