x86/apic: Always explicitly disarm TSC-deadline timer (2024-10-15 05:45:18 -0700)

----------------------------------------------------------------
- Explicitly disable the TSC deadline timer when going idle to address
some CPU errata in that area

- Do not apply the Zenbleed fix on anything else except AMD Zen2 on the
late microcode loading path

- Clear CPU buffers later in the NMI exit path on 32-bit to avoid
register clearing while they still contain sensitive data, for the
RDFS mitigation

- Do not clobber EFLAGS.ZF with VERW on the opportunistic SYSRET exit
path on 32-bit

- Fix parsing issues of memory bandwidth specification in sysfs for
resctrl's memory bandwidth allocation feature

- Other small cleanups and improvements

----------------------------------------------------------------
John Allen (1):
x86/CPU/AMD: Only apply Zenbleed fix for Zen2 during late microcode load

Martin Kletzander (1):
x86/resctrl: Avoid overflow in MB settings in bw_validate()

Nathan Chancellor (1):
x86/resctrl: Annotate get_mem_config() functions as __init

Pawan Gupta (3):
x86/entry_32: Do not clobber user EFLAGS.ZF
x86/entry_32: Clear CPU buffers after register restore in NMI return
x86/bugs: Use code segment selector for VERW operand

Richard Gong (1):
x86/amd_nb: Add new PCI ID for AMD family 1Ah model 20h

Zhang Rui (1):
x86/apic: Always explicitly disarm TSC-deadline timer
