The hardware spinlock binding already supplied the 'hwlock-names' property
to match and get a specific hwlock, but did not supply one API for users
to get a specific hwlock by the hwlock name. So this patch introduces one
API to support this requirement.

Hi, Marc
Current system only supports (NR_IRQS + 8196) interrupts. It's not
enough on ARM64
server, on D06 we have several pcie devices and each device supports 256
VMs and each
VM uses 64 interrupts. Can we set NR_IRQS to a bigger value to support
more interrupts ?

That's broken. #AC wants to be enabled early as any other exception. The
reason why you cannot enable it is because your exception handler is a

There is a special case that the size is "(N << KASAN_SHADOW_SCALE_SHIFT)
Pages plus X", the value of X is [1, KASAN_SHADOW_SCALE_SIZE-1]. The
operation "size >> KASAN_SHADOW_SCALE_SHIFT" will drop X, and the roundup
operation can not retrieve the missed one page. For example: size=0x28006,

The hardware configuration register has some useful bits which can be
used by guests. Implement McStatusWrEn which can be used by guests when
injecting MCEs with the in-kernel mce-inject module.
For that, we need to set bit 18 - McStatusWrEn - first, before writing
the MCi_

Hi all,
there's this mce-inject.ko module in the kernel which allows for
injecting real MCEs and thus test the MCE handling code.
It is doubly useful to be able to inject same MCEs in a guest so that
testing of the MCE handling code can happen even easier/faster. In order

We recently made enabling LPIs a lot stricter, by checking that
they are disabled before we enable them. By doing so, we missed
the CPU hotplug case altogether, where we leave LPIs enabled
on hotplug off (we expect the CPU to eventually come back),
and won't write a different value anyway on hotplu
