It's not explicitly marked as asmlinkage, but invoked from x86_32
startup code with parameters on stack.

No other architectures define early_printk and none of them are affected
by this change, since defines asmlinkage as empty token.

[PATCH 2/3] x86: coding style fixes to arch/x86/kernel/early_printk.c

Remove two:
ERROR: do not initialise statics to 0 or NULL

This patch is changing the binary output:

da32f5cd8f248970e4809e1005393e95  early_printk.o.before

because the two variables moved to another section. No
change in functionality.

Not necessary to expose it, also fixes sparse warning.

Instead of using magic macros for boot_params access, simply use the

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
