um: remove PAGE_SIZE alignment in linker script causing kernel segfault.
|
||||||
|
|
||||||
|
The linker script cleanup that I did in commit
|
||||||
|
5d150a97f9391f5bcd7ba0d59d7a11c3de3cea80 accidentally introduced an
|
||||||
|
ALIGN(PAGE_SIZE) when converting to use INIT_TEXT_SECTION; Richard
|
||||||
|
Weinberger reported that this causes the kernel to segfault with
|
||||||
|
CONFIG_STATIC_LINK=y.
|
||||||
|
|
||||||
|
I'm not certain why this extra alignment is a problem, but it seems likely
|
||||||
|
it is because previously
|
||||||
|
|
||||||
|
__init_begin = _stext = _text = _sinittext
|
||||||
|
|
||||||
|
and with the extra ALIGN(PAGE_SIZE), _sinittext becomes different from the
|
||||||
|
rest. So there is likely a bug here where something is assuming that
|
||||||
|
_sinittext is the same as one of those other symbols. But reverting the
|
||||||
|
accidental change fixes the regression, so it seems worth committing that
|
||||||
|
now.
