Kernel prepatch 5.19-rc7

The 5.19-rc7 kernel prepatch is out fortesting.

We obviously had that whole "Retbleed" thing, and it does show upin both the diffstat and the shortlog, and rc7 is definitely biggerthan usual. And also as usual, when we've had one of thoseembargoed hw issues pending, the patches didn't get the opendevelopment, and then as a result missed all the usual sanitychecking by all the automation build and test infrastructure wehave. So no surprise - there's been various small fixup patchesafterwards too for some corner cases.

That said, last week there were two other development trees thatindependently also asked for an extension, so 5.19 will be one ofthose releases that have an additional rc8 next weekend before thefinal release.
