Subject: platform/chrome: chromeos_pstore: set user space log size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1c7c51347f2e2ff5920cee1b54c683e2af06bd81;p=linux.git

platform/chrome: chromeos_pstore: set user space log size

On x86 ChromiumOS devices, the pmsg_size is set to 0 (check
/sys/module/ramoops/parameters/pmsg_size): this prevents use of
pstore-pmsg, even if CONFIG_PSTORE_PMSG is enabled. Set pmsg_size
to a value that is consistent with the size used on non-x86 ChromiumOS
devices.
