raphael_defconfig: increase sbalance pooling rate to 10s
commit 54d190b8af
Author: Sultan Alsawaf <sultan@kerneltoast.com>
Date: Wed Dec 4 15:53:22 2024 -0800
sbalance: Fix severe misattribution of movable IRQs to the last active CPU
Due to a horrible omission in the big IRQ list traversal, all movable IRQs
are misattributed to the last active CPU in the system since that's what
`bd` is last set to in the loop prior. This horribly breaks SBalance's
notion of balance, producing nonsensical balancing decisions and failing to
balance IRQs even when they are heavily imbalanced.
Fix the massive breakage by adding the missing line of code to set `bd` to
the CPU an IRQ actually belongs to, so that it's added to the correct CPU's
movable IRQs list.

Author: Sultan Alsawaf <sultan@kerneltoast.com>
Date: Wed Dec 4 14:31:52 2024 -0800
sbalance: Don't race with CPU hotplug
When a CPU is hotplugged, cpu_active_mask is modified without any RCU
synchronization. As a result, the only synchronization for cpu_active_mask
provided by the hotplug code is the CPU hotplug lock.
Furthermore, since IRQ balance is majorly disrupted during CPU hotplug due
to mass IRQ migration off a dying CPU, SBalance just shouldn't operate
while a CPU hotplug is in progress.
Take the CPU hotplug lock in balance_irqs() to prevent races and mishaps
during CPU hotplugs.
