The ioremap() function is intended for mapping MMIO. For RAM, the
memremap() function should be used. Convert calls from ioremap() to
memremap() when re-mapping RAM.This will be used later by SME to control how the encryption mask is
applied to memory mappings, with certain memory locations being mapped
decrypted vs encrypted.Signed-off-by: Tom Lendacky

setup_earlycon() will now match and register the desired earlycon
from the param string (as if 'earlycon=...' had been set on the
command line). Use setup_earlycon() from existing arch call sites
which start an earlycon directly.Acked-by: Rob Herring

efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP
EFI system table and setup an early console for printk output. The
routine uses ioremap/iounmap to setup access to the HCDP/PCDP table
information.The call to ioremap is happening early in the boot process which leads
to a panic on x86_64 systems:panic+0x01ca

HCDP/PCDP table for early console setup.Signed-off-by: Greg Pearson

It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures. ia64 (in common with several
other 64-bit architectures) currently uses unsigned long. Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.Note that userspace will still see __u64 defined as unsigned long. This
is important as it affects C++ name mangling.[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
u64 for start/end rather than unsigned long]Signed-off-by: Matthew Wilcox

Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and
include/asm-x86_64/serial.h. the serial8250_ports need to be probed late in
serial initializing stage. the console_init=>serial8250_console_init=>
register_console=>serial8250_console_setup will return -ENDEV, and console
ttyS0 can not be enabled at that time. need to wait till uart_add_one_port in
drivers/serial/serial_core.c to call register_console to get console ttyS0.
that is too late.Make early_uart to use early_param, so uart console can be used earlier. Make
it to be bootconsole with CON_BOOT flag, so can use console handover feature.
and it will switch to corresponding normal serial console automatically.new command line will be:
console=uart8250,io,0x3f8,9600n8
console=uart8250,mmio,0xff5e0000,115200n8
or
earlycon=uart8250,io,0x3f8,9600n8
earlycon=uart8250,mmio,0xff5e0000,115200n8it will print in very early stage:
Early serial console at I/O port 0x3f8 (options '9600n8')
console [uart0] enabled
later for console it will print:
console handover: boot [uart0] -> real [ttyS0]Signed-off-by:

Almost all users of the table addresses from the EFI system table want
physical addresses. So rather than doing the pa->va->pa conversion, just keep
physical addresses in struct efi.This fixes a DMI bug: the efi structure contained the physical SMBIOS address
on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap()
on a virtual address on ia64.This is essentially the same as an earlier patch by Matt Tolentino:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2
except that this changes all table addresses, not just ACPI addresses.Matt's original patch was backed out because it caused MCAs on HP sx1000
systems. That problem is resolved by the ioremap() attribute checking added
for ia64.Signed-off-by: Bjorn Helgaas

Resend 2 with changes per Bjorn Helgaas comments. Changes from original:
+ Change globals to vga_console_iobase/vga_console_membase and make them
unconditional.
+ Address style-related comments.Patch to extend the PCDP vga setup code to support PCI io/mem translations
for the legacy vga ioport and ram spaces on architectures (e.g. altix) which
need them.Summary of the changes:
drivers/firmware/pcdp.c
drivers/firmware/pcdp.h
-----------------------
+ add declaration for the spec-defined PCI interface struct (pcdp_if_pci)
as well as support macros.+ extend setup_vga_console() to know about pcdp_if_pci and add a couple of
globals to hold the io and mem translation offsets if present.arch/ia64/kernel/setup.c
------------------------
+ tweek early_console_setup() to allow multiple early console setup routines
to be called.include/asm-ia64/vga.h
----------------------
+ make VGA_MAP_MEM vga_console_membase awareSigned-off-by: Mark Maule

The HCDP specs (i.e., PCDP revision < 3) allow zero as a default value for
baud rate and data bits. So if firmware doesn't supply them, let
early_serial_console_init() probe for them rather than telling it the baud
rate is zero.Also, update the URL for the PCDP spec.

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!
