misc: sgi-gru: Don't disable preemption in GRU driver

2024-10-09T19:47:01+00:00

Disabling preemption in the GRU driver is unnecessary, and clashes with sleeping locks in several code paths. Remove preempt_disable and preempt_enable from the GRU driver. Signed-off-by: Dimitri Sivanich Signed-off-by: Linus Torvalds

x86/cpu: Relocate sync_core() to sync_core.h

2020-07-27T10:42:06+00:00

Having sync_core() in processor.h is problematic since it is not possible to check for hardware capabilities via the *cpu_has() family of macros. The latter needs the definitions in processor.h. It also looks more intuitive to relocate the function to sync_core.h. This changeset does not make changes in functionality.

Use no-op messages in place of cross-partition interrupts when nacking a put message in the GRU. This allows us to remove MMR's as a destination from the GRU driver.
