2020-10-25treewide: Convert macro and uses of __section(foo) to __section("foo")Joe Perches1-4/+4
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/[email protected]/2-convert_section.pl Signed-off-by: Joe Perches <[email protected]> Reviewed-by: Nick Desaulniers <[email protected]> Reviewed-by: Miguel Ojeda <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2010-08-02x86, setup: reorganize the early console setupYinghai Lu1-135/+1
Separate early_serial_console from tty.c This allows for reuse of early_serial_console.c/string.c/printf.c/cmdline.c in boot/compressed/. -v2: according to hpa, don't include string.c etc -v3: compressed/misc.c must have early_serial_base as static, so move it back to tty.c for setup code Signed-off-by: Yinghai Lu <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: H.

2010-07-14x86, setup: Only set early_serial_base after port is initializedYinghai Lu1-30/+33
putchar is using early_serial_base to check if port is initialized. So we only assign it after early_serial_init() is called, in case we need use VGA to debug early serial console. Also add display for port addr and baud. -v2: update to current tip Acked-by: Pekka Enberg <[email protected]> Signed-off-by: Yinghai Lu <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: H.

2010-07-13x86, setup: Make the setup code also accept console=uart8250Yinghai Lu1-1/+58
Make the boot code also accept the console=uart8250,io,0x2f8,115200n form of early console. Also add back simple_guess_base(), otherwise those simple_strtoull(,,0) are not going to work.

2010-07-12x86, setup: Early-boot serial I/O supportPekka Enberg1-6/+105
This patch adds serial I/O support to the real-mode setup (very early boot) printf(). It's useful for debugging boot code when running Linux under KVM, for example. The actual code was lifted from early printk.

2008-11-25x86: use limited register constraint for setnzSteven Rostedt1-1/+1
Impact: build fix with certain compilers GCC can decide to use %dil when "r" is used, which is not valid for setnz. This bug was brought out by Stephen Rothwell's merging of the branch tracer into linux-next.
