Analyze and fix the following issue in the Linux kernel code: keys: Fix overwrite of key expiration on instantiation
Problem Details: The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expir...

Analyze and fix the following issue in the Linux kernel code: drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
Problem Details: We don't get the right offset in that case. The GPU has an unused 4K area of the register BAR space into which you can remap registers. We remap the HDP flush registers into this space to allow userspace (CPU or GPU) to flush the HDP when it updates VRAM. However, on systems with >4K pages, we end u...
