This mirrors dmu_read_impl(), zeroing out the tail end of the buffer and clipping the read to what's contained by the block that exists. This fixes an issue that arose during the 13.1 release process; in 13.1-RC1 and later, setting up GELI+ZFS will result in a failure to boot. The culprit is this, which causes us to fail to load geom_eli.ko as there's a residual portion after the single datablk that should be zeroed out.

UEFI provides a protocol for accessing randomness. This is a good way to gather early entropy, especially when there's no driver for the RNG on the platform (as is the case on the Marvell Armada8k (MACCHIATObin) for now). If the entropy_efi_seed option is enabled in loader.conf (default: YES) obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a "module" of name "efi_rng_seed" and type "boot_entropy_platform"; if present, ingest it into the kernel RNG.

When the timer drops from double to single digits, a spare 'e' is left on the end of the line as we don't overwrite it. Include an extra space at the end to account for this and overwrite the leftover character. PR: 259429 (cherry picked from commit bb4c691299c5d699cea29e18fef96bda1cef13da)
After b4cb3fe0e39a, loader started crashing on PowerPC64, with a Program Exception (700) error. The problem was that archsw was used before being initialized, with the new mount feature. This change fixes the issue by initializing archsw earlier, before setting currdev, that triggers the mount.

This helps mesuring what's happening when we load the kernel/modules/mfsroot. This also adds TSENTER2 which uses the third argument of TSRAW, same as in the kernel.

Bootloaders for powerpc are not built as position independent code. Since bsd.prog.mk is used for building, when PIE is enabled, the PIE flags are added and that causes the build to fail. Adding MK_PIE=no stops bsd.prog.mk from adding PIE specific flags.

When performing buildworld for MIPS with PIE enabled, the build fails with "position-independent code requires '-mabicalls'" message. -mno-abicalls and -fno-pic flags are explicitly set in MIPS ubldr makefile, so to work around this problem, set MK_PIE=no for MIPS ubldr.
