Time to drop wrmsrl()/rdmsrl()?

Hi Ingo,

Keeping them around only causes churn now, so probably it is time to drop
them?

I think all of their uses were changed to wrmsrq()/rdmsrq(), but they are
coming back, and with the latest Linux 6.19-rc1 tag, I get:

$git grep -w rdmsrl
arch/x86/events/amd/uncore.c:   rdmsrl(hwc->event_base, new);
arch/x86/include/asm/msr.h:#define rdmsrl(msr, val) rdmsrq(msr, val)
arch/x86/kernel/cpu/resctrl/monitor.c:  rdmsrl(MSR_IA32_QM_CTR, msr_val);
drivers/hv/mshv_vtl_main.c:                             rdmsrl(reg_table[i].msr_addr, *reg64);
drivers/idle/intel_idle.c:      rdmsrl(MSR_PKG_CST_CONFIG_CONTROL, msr_val);
drivers/idle/intel_idle.c:      rdmsrl(MSR_PKG_CST_CONFIG_CONTROL, msr_val);


Thanks!
