Nexoniarz d437e42b49 LDLS: every MDIO read was RFLAGS; ACPI: an Embedded Controller 
On the TUF A15 Linux's r8169 found its PHY and read its ID as 0x02460246.
mdio-bus keeps the register it has just read in r11 across
preempt_enable(), which on x86 is `decl %gs:__preempt_count; je` to a
call that preserves every register. LDLS gave __preempt_count zeroes, so
the count reached zero and the call was made -- to a logging stub,
whose syscall left RFLAGS (0x246) in r11. __preempt_count now starts at
PREEMPT_ENABLED (x86 keeps NEED_RESCHED inverted), and preempt_schedule
and its notrace twin are a bare ret.

The same laptop reported its battery full and on AC, unplugged. The EC
owns both, and with no EmbeddedControl handler _REG never told the
firmware the EC was usable, so _BST and _PSR answered their fallbacks.
The EC is found by PNP0C09 or the ECDT and served by the ACPI 12.3
byte protocol, installed before _INI. SCI queries are not handled yet.
