Ubuntu commit 8bf5a702a8a3 ("UBUNTU: [Config] updateconfigs for DIMLIB")
enabled the DIMLIB feature and broadcom/mellanox/ena drivers have been
updated to use it. This kernel's config happens to depend on at least
one of the affected drivers and therefore now DIMLIB is selected.
UBUNTU: [Config] oracle: Disable TSX by default when possible
Turn on CONFIG_X86_INTEL_TSX_MODE_OFF to disable Intel's Transactional
Synchronization Extensions (TSX) feature by default. TSX can only be
disable on certain, newer processors that support the IA32_TSX_CTRL MSR
via a microcode update. Intel says that future processors will also
support the MSR. On processors that support the MSR, TSX will be
disabled unless the system administrator overrides the configuration
with the "tsx" kernel command line option.
