Subject: [PATCH] arm64: Use CONFIG_ARM64_VA_BITS to initialize VA_BITS_ACTUAL
|
||||
|
||||
We can get VA_BITS_ACTUAL from CONFIG_ARM64_VA_BITS by guess.
|
||||
|
||||
Without this patch, we may need to use "--machdep vabits_actual=48" to
|
||||
set the VA_BITS_ACTUAL.

Subject: [PATCH] arm64: deduce the start address of kernel code, based on
|
||||
kernel version
|
||||
|
||||
After kernel commit e2a073dde921 ("arm64: omit [_text, _stext) from
|
||||
permanent kernel mapping"), the range [_text, _stext] is reclaimed. But
|
||||
the current crash code still assumes kernel starting from "_text".
|
||||
|
||||
This change only affects the vmalloced area on arm64 and may result a
|
||||
false in arm64_IS_VMALLOC_ADDR().
|
||||
|
||||
Since vmcore has no extra information about this trival change, it can
|
||||
only be deduced from kernel version, which means ms->kimage_text can not
|
||||
be correctly initialized until kernel_init() finishes. Here on arm64, it
|
||||
can be done at the point machdep_init(POST_GDB). This is fine
|
||||
since there is no access to vmalloced area at this stage.
