Subject: [PATCH v2 09/21] memblock: drop memblock_alloc_base()
Date: Mon, 21 Jan 2019 08:03:56 +0000	[thread overview]
Message-ID: <1548057848-15136-10-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>

The memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter and panics if the allocation
fails. Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.

Subject: [PATCH v2 09/21] memblock: drop memblock_alloc_base()
Date: Mon, 21 Jan 2019 10:03:56 +0200	[thread overview]
Message-ID: <1548057848-15136-10-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>

The memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter and panics if the allocation
fails. Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.

Subject: [PATCH v2 09/21] memblock: drop memblock_alloc_base()
Date: Mon, 21 Jan 2019 10:03:56 +0200	[thread overview]
Message-ID: <1548057848-15136-10-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>

The memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter and panics if the allocation
fails. Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.
