Linux 6.6.65

by Greg Kroah-Hartman

I'm announcing the release of the 6.6.65 kernel. This release only fixes a build regression for openrisc, and a runtime regression for domU guests. If you don't have problems with them, no need to upgrade. The updated 6.6.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 +- arch/openrisc/include/asm/fixmap.h | 31 +------------------------------ arch/x86/platform/pvh/head.S | 22 +--------------------- 3 files changed, 3 insertions(+), 52 deletions(-) Dawei Li (1): openrisc: Use asm-generic's version of fix_to_virt() & virt_to_fix() Greg Kroah-Hartman (3): Revert "x86/pvh: Call C code via the kernel virtual mapping" Revert "x86/pvh: Set phys_base when calling xen_prepare_pvh()" Linux 6.6.65

[PATCH 6.12.y] media: ipu6: use the IPU6 DMA mapping APIs to do mapping

by Stanislaw Gruszka

From: Bingbu Cao <bingbu.cao(a)intel.com> commit 1d4a000289979cc7f2887c8407b1bfe2a0918354 upstream. dma_ops is removed from the IPU6 auxiliary device, ISYS driver should use the IPU6 DMA mapping APIs directly instead of depending on the device callbacks.
